Display refers to the physical display unit. Screen refers to everything you see on the monitor's display, such as measurements, alarms, patient data, and so forth. FM30 Whenever a monitors identifier appears to the left of a heading or paragraph, it means that the information applies to that monitor only. Where the information applies to all models, no distinction is made. Avalon CL Avalon CTS Whenever one of these identifiers appear to the left of a heading or paragraph, it means that the information applies to that cableless transducer system. Where the information applies to both systems, no distinction is made. For installation instructions and technical description, see the corresponding Service Guide of the fetal monitors. Confirm Fetal Life Before Using the Monitor Fetal monitoring technology available today is not always able to differentiate a fetal heart rate (FHR) signal source from a maternal heart rate (MHR) source in all situations. Therefore, you should confirm fetal life by independent means before starting to use the fetal monitor, for example, by palpation of fetal movement or auscultation of fetal heart sounds using a fetoscope, stethoscope, or Pinard stethoscope. If you cannot hear the fetal heart sounds, and you cannot confirm fetal movement by palpation, confirm fetal life using obstetric ultrasonography. Continue to confirm that the fetus is the signal source for the FHR during monitoring. Be aware that:
a maternal HR trace can exhibit features that are very similar to those of an FHR trace, even including accelerations and decelerations. Do not rely solely on trace pattern features to identify a fetal source. Fetal Movement Profile (FMP) annotations on a fetal trace alone may not always indicate that the fetus is alive. The body of a deceased fetus can move and cause the monitor to annotate fetal body movements. Here are some examples where the maternal HR can be misidentified as the FHR. When using an ultrasound transducer:
Misidentification may occur when the maternal HR is higher than normal (especially when it is It is possible to pick up maternal signal sources, such as the aorta or other large vessels. over 100 bpm). When using a fetal scalp electrode:
Electrical impulses from the maternal heart can sometimes be transmitted to the fetal monitor through a recently deceased fetus via the spiral scalp electrode cable, appearing to be a fetal signal source. The recorded maternal HR (and any artifact) can be misinterpreted as an FHR (especially when it is over 100 bpm). When Fetal Movement Profile (FMP) is enabled:
FMP annotations in the absence of fetal life may be a result of:
Movement of the deceased fetus during or following maternal movement. Movement of the deceased fetus during or following manual palpation of fetal movement
(especially if the pressure applied is too forceful). 10 1 Introduction Movement of the ultrasound transducer. The ultrasound transducer detecting a maternal movement source, such as the mother coughing. See also Monitoring FHR and FMP Using Ultrasound on page 165 and Monitoring FHR Using DECG on page 199. To reduce the possibility of mistaking the maternal HR for an FHR, it is recommended that you monitor both maternal and fetal heart rates. The monitor's cross-channel verification (CCV) feature can help by automatically detecting when a maternal HR coincides with an FHR. For further details, see Cross-Channel Verification (CCV) on page 159. Introducing the Avalon Family of Fetal Monitors The Avalon family of fetal monitors consists of the Avalon FM20, FM30, FM40, and FM50. While the FM20/FM30 and the FM40/FM50 have different form factors, the method of operation is very similar for all monitors. The Avalon fetal monitors also share transducers, accessories, software, and are compatible with the Avalon CL, and Avalon CTS Fetal Transducer Systems.

Safety Information In this guide:
A warning alerts you to a potential serious outcome, adverse event or safety hazard. Failure to observe a warning may result in death or serious injury to the user or patient. A caution alerts you to where special care is necessary for the safe and effective use of the product. Failure to observe a caution may result in minor or moderate personal injury or damage to the product or other property, and possibly in a remote risk of more serious injury. 13 1 Introduction Electrical Hazards WARNING Electrical shock hazard: Do not open the monitor housing. Refer all servicing to qualified service personnel. Always use the supplied power cord with the earthed mains plug to connect to an earthed AC mains socket. Never adapt the mains plug from the fetal monitor to fit an unearthed AC mains socket. Do not use AC mains extension cords or multiple portable socket-outlets. FM20/FM30 only: The protective earth conductor is required for EMC purposes. It has no protective function against electric shock. Double and/or reinforced insulation protects this device against electric shock. Do not connect any devices that are not supported as part of a system. Any non-medical device placed and operated in the patients vicinity must be powered with an approved isolation transformer that ensures mechanical fixing of the power cords, and covering of any unused power outlets. The fetal/maternal monitor is NOT intended for use during defibrillation, electro-surgery, or MRI. Remove all transducers, sensors, and accessories before performing electro-surgery, defibrillation, or MRI, otherwise harm to the patient or the user can result. Do not touch the charging contacts for the cableless transducers at the Avalon CL base station while you are touching the patient. Leakage currents: If several items of equipment used to monitor a patient are interconnected, the resulting leakage current may exceed allowable limits. Radio Frequency Interference WARNING Short range radio connections are subject to interruption due to interference from other radio sources in the vicinity, including microwaves, bluetooth devices, WLAN devices (802.11b,g,n), and cordless phones. Depending on the strength and duration of the interference, the interruption may occur for an extended period. A loss of connection, due to moving out-of-range, interference, or for other reasons, is indicated with a No Host Monitoring INOP (here the host is the fetal monitor) on the IntelliVue CL NBP or CL SpO2 Pods, or a No Host Monitoring, or cl NBP Disconnect, or cl SpO Disconnect INOP at the fetal monitor. Correct channel configuration is important, refer to the Service Guides and the Configuration Guide for details. To avoid magnetic interference affecting the mode of the pacemaker, ensure that the Avalon CL base station does not come into close contact with implanted pacemakers. This equipment generates, uses, and radiates radio-frequency energy, and if it is not installed and used in accordance with its accompanying documentation, may cause interference to radio communications. Operation of this equipment in a residential area may cause interference, in which case the users must take whatever measures may be required to correct the interference. Do not use cordless/mobile phones or any other portable RF communication system within the patient vicinity, or within a 1.0 m radius of any part of the fetal monitoring system. 14 1 Introduction For paced patients: The radiated SRR power of the CL SpO2, CL NBP Pods, CL F&M Pod, and the CL Wide Range Pod, and other sources of radio-frequency energy, when used in very close proximity of a pacemaker, might be sufficient to interfere with pacemaker performance. Due to shielding effects of the body, internal pacemakers are somewhat less vulnerable than external pacemakers. However, caution should be exercised when monitoring paced patients. In order to minimize the possibility of interference, avoid positioning and wearing the Cableless Measurement Devices in very close proximity to a pacemaker. Consult the pacemaker manufacturer for information on the RF susceptibility of their products. Use Environment WARNING Explosion Hazard:
Do not use in the presence of flammable anesthetics, such as a flammable anesthetic mixture with air, oxygen, nitrous oxide, or in oxygen rich environment. Use of the devices in such an environment may present an explosion hazard. Use only Philips batteries part number M4605A with the FM20 or FM30 with battery option. Use of a different battery may present a risk of fire or explosion. Environmental Specifications:
The performance specifications for the monitors, measurements, and accessories apply only for use within the temperature, humidity, and altitude ranges specified in Environmental Specifications on page 287. Liquid Ingress:
Do not operate the monitor if it is wet. If you spill liquid on the monitor, contact your service personnel, or Philips service engineer. Never immerse the fetal monitor or the CL base station in liquid. You must protect them against water sprays or splashes. Place the fetal monitor and the CL base station where there is no chance of contact with, or falling into water or other liquids. Do not perform underwater monitoring (for example, in a bath or shower) using wired transducers. The CL Fetal & Maternal Pod is not intended for underwater monitoring. The contacts between the CL Fetal & Maternal Pod and the electrode patch have to be kept dry at all times. The CL Fetal
& Maternal Pod mounted on the electrode patch, can be worn underneath a shower, as long as the CL Fetal & Maternal Pod stays mounted. Radio transmissions in the shower may be compromised. Heat Exposure:
Do not dry equipment using heating devices such as heaters, ovens (including microwave ovens), hair dryers, and heating lamps. Do not put equipment or accessories in autoclave (for sterilization). Positioning Equipment:
The device should not be used adjacent to, or stacked with, other equipment unless otherwise specified. 15 1 Introduction Prohibited Environments:
The monitors and their transducers, Pods, and accessories are not intended for use in an MRI environment or in an oxygen-enriched environment (for example, hyperbaric chambers). Alarms WARNING Do not rely exclusively on the audible alarm system for fetal monitoring. Adjustment of alarm volume to a low level or off during monitoring may result in a dangerous situation. Remember that the most reliable method of fetal monitoring combines close personal surveillance with correct operation of monitoring equipment. Alarm systems of the monitor and those of the connected obstetrical information and surveillance system are independent and not synchronized. In INOP only mode, no fetal/maternal patient alarms are enabled or indicated. Accessories WARNING Philips' approval: Use only Philips-approved accessories. Using non-Philips-approved accessories may compromise device functionality and system performance, and cause a potential hazard. Reuse: Never reuse disposable transducers, sensors, accessories, and so forth, that are intended for single use, or single patient use only. Reuse may compromise device functionality and system performance, and cause a potential hazard. Electromagnetic compatibility: The use of accessories, transducers, and cables other than those specified may result in increased electromagnetic emissions or decreased electromagnetic immunity of the device. Damage: Do not use a damaged sensor or one with exposed electrical contacts. Cables and tubing: When connecting devices for acquiring measurements, always position cables and NBP tubing carefully to avoid entanglement or potential strangulation. 16 Security Information Protecting Personal Information 1 Introduction Protecting personal health information is a primary component of a security strategy. Each facility using the monitors must provide the protective means necessary to safeguard personal information consistent with country laws and regulations, and consistent with the facilitys policies for managing this information. Protection can only be realized if you implement a comprehensive, multi-layered strategy (including policies, processes, and technologies) to protect information and systems from external and internal threats. As per its intended use, the patient monitor operates in the patient vicinity and contains personal and sensitive patient data. This also includes the trace print-outs at the monitor. The monitor also includes controls to allow you to adapt the monitor to the patient's care model. To ensure the patient's safety and protect their personal health information, you need a security concept that includes:
Physical security access measures - access to the monitor must be limited to authorized users. It is essential that you consider physical security measures to ensure that unauthorized users cannot gain access. Operational security measures - for example, ensuring that patients are discharged after monitoring in order to remove their data from the monitor. Procedural security measures - for example, assigning only staff with a specific role the right to use the monitors. In addition, any security concept must consider the requirements of local country laws and regulations. Always consider data security aspects of the network topology and configuration when connecting patient monitors to shared networks. Your medical facility is responsible for the security of the network, where sensitive patient data from the monitor may be transferred. When a monitor is returned for repair, disposed of, or removed from your medical facility for other reasons, always ensure that all patient data is removed from the monitor by ending monitoring for the last patient (see Discharging a Patient on page 148). Also select Erase All in the Stored Data Recording menu, to erase all stored data. NOTE Log files generated by the monitors and measurement modules are used for system troubleshooting and do not contain protected health data. About HIPAA Rules If applicable, your facilitys security strategy should include the standards set forth in the Health Insurance Portability and Accountability Act of 1996 (HIPAA), introduced by the United States Department of Health and Human Services. You should consider both the security and the privacy rules and the HITECH Act when designing policies and procedures. For more information, please visit:
http://www.hhs.gov/ocr/privacy/
17 1 Introduction About the EU Directives If applicable, your facilitys security strategy should include the practices set forth in the Directive on the protection of individuals with regard to the processing of personal data and on the free movement of such data (Directive 95/46/EC of the European Parliament and of the Council of 24 October 1995). In addition, your facility should also take into account any additional, more stringent standards put forward by any individual EU countries; that is, Germany, France, and so on.

You may not have all of these features, depending on the fetal monitor configuration purchased. What's New in Release L.3 Avalon CL Fetal & Maternal Pod The Avalon CL Fetal & Maternal Pod is an extension of the Avalon CL solution. The Avalon CL Fetal & Maternal Pod is used together with a single use patch with five abdominal electrodes. Prior to use, the Avalon CL Fetal & Maternal Pod is charged and assigned at the Avalon CL base station. The Avalon CL Fetal & Maternal Pod is used with singleton pregnancies. This solution provides especially benefits to patients with high body mass index (BMI), although it can be used for all patients. The Avalon CL Fetal & Maternal Pod includes the following features:
The Avalon CL Fetal & Maternal Pod measures fetal heart rate (aFHR), maternal heart rate (aHR), and uterine activity (aToco) from electrical signals. The cl F&M Electrode Status window at the monitor gives an overview of the current electrode contact status, when the CL Fetal & Maternal Pod is placed on the electrode patch, and the patch, and the electrodes are applied to the patient's abdominal skin. The window can be opened by selecting the new SmartKey cl F&M Status, or selecting the corresponding function in the main setup menu. The Avalon CL Fetal & Maternal Pod and the CL Wide Range Pod are assigned at the CL base station in the same easy way as the IntelliVue CL Pods. The functions Finder LED and Call Patient work also with the Avalon CL Fetal & Maternal Pod. See Avalon CL Fetal & Maternal Pod on page 21, CL Fetal & Maternal Electrode Patch on page 91, Applying the CL Fetal & Maternal Patch and Pod on page 100, and CL Pod Assignment on page 99. 21 2 What's New Avalon CL Wide Range Pod The Avalon CL Wide Range Pod is an extension of the Avalon CL solution. The Avalon CL Wide Range Pod extends the signal range of the cableless measurements. It transmits the cableless measurement signals via the hospital WLAN/WiFi to the fetal monitors. Wearing the CL Wide Range Pod, the patient can walk freely within the hospital's WLAN/WiFi range during monitoring. Prior to use, the Avalon CL Wide Range Pod is charged and assigned at the Avalon CL base station. A new WLAN symbol is printed on the trace to indicate the use of an assigned and active Avalon CL Wide Range Pod. During monitoring with an active Avalon CL Wide Range Pod, the sound from the fetal heart rate is replaced by an artificial QRS sound (when the patient is monitored with a CL US transducer or CL F&M Pod). See CL Wide Range Pod on page 91. Dawes/Redman Dawes/Redman is a method of fetal monitoring trace interpretation for helping to assess fetal well-being. The algorithm based on the Dawes/Redman criteria uses the parameters fetal heart rate, gestational age, fetal movement, accelerations and decelerations, and long, and short term variability to generate a report. Not available in the USA and territories relying on FDA market clearance. Support of XDS Remote Display The fetal monitor software supports the IntelliVue XDS Remote Display functionality only in combination with IntelliSpace Perinatal revision K or higher. From the user interface of the IntelliSpace Perinatal system, you can access all screen-operable functions of the currently connected fetal monitor. These functions include for example, starting and stopping physiological measurements, changing measurement modes, changing alarm limits, and silencing alarms. New Alarm Behavior of CL Battery Empty INOP The CL <xxx> Battery Empty INOP issued by the CL devices and the fetal monitor has a new alarm behavior:
At the fetal monitor, it is issued now with a cyan INOP alarm and tone. At CL devices (CL transducers and CL Pods), it is issued now with a tone. See Patient Alarms and INOPs on page 129. Using CL Pods with FM20/30 #E25 The CL Pods can now also be used with a battery operated FM20 or FM30 (option #E25). The CL Pods can be assigned and activated. The CL F&M Pod can also be charged. See Using Batteries on page 110. Entering Notes - Type a Note In the menu Enter Note, it is now possible to enter a note manually, instead of selecting one of the pre-configured notes. To enter a note, select the new menu item Type a note. A window with a touch keypad opens. The typed note can be up to 30 characters long. See Typing Notes on page 70. 22 What's New in Release J.3 Avalon CL Transducer System 2 What's New The Avalon CL Transducer System provides cableless monitoring with the Avalon FM20/FM30 and FM40/FM50 with the same functionality and performance as the wired measurement devices (e.g. twin and triplets monitoring). The Avalon CL Transducer System has a straight-forward handling and operating concept. The CL transducers are assigned by simply docking them at the CL base station, no further configuration is necessary. The Avalon CL Transducer System includes the following features:
Cableless monitoring of twins and triplets (see Monitoring Twin FHRs on page 183 and Monitoring Triple FHRs on page 191) Cableless maternal measurement Pods CL SpO2 and CL NBP (see IntelliVue CL Pods on page 92) Maternal pulse from a CL Toco+ MP (Smart Pulse) transducer (see Monitoring Maternal Heart /
Pulse Rate on page 221) A cableless ECG/IUP transducer measuring IUP or fetal/maternal ECG (see Monitoring MECG Wave on page 225 and Monitoring FHR Using DECG on page 199) Watertight cableless transducers that can be used to monitor in water (see Underwater Monitoring on page 108) Patient call that pages an ambulating mother with an audible signal emitted by the worn CL transducers (see Calling Patients on page 93) Out-of-range audible signal emitted by the worn CL transducers to inform an ambulating mother that she has reached the limit of the active signal area-of-reach (see Standard Radio Range of CL Transducers on page 87) A transducer finder LED on all CL transducers to help identify the assigned transducer (see Cableless Transducer LED Indication on page 86) Support For Use of Maternal Cableless Measurement Devices The IntelliVue CL measurement Pods are patient-worn, battery-powered measurement devices for SpO2 and NBP. The devices provide measurement values on the built-in display and communicate them to the fetal monitor using the wireless short range radio (SRR) interface of the Avalon CL base station (see IntelliVue CL Pods on page 92). Maternal Temperature Measurement To measure maternal temperature, the new optional tympanic thermometer (866149) is available for the Avalon fetal monitors (Monitoring Maternal Temperature on page 249). The measurement data is:
documented and printed out at the local recorder, and transmitted to the obstetrical information and surveillance system. displayed as a numeric on the screen. 23 2 What's New Manually Entered Maternal Temperature Measurements Manually measured temperatures can be entered at the fetal monitor. They are displayed as a numeric on screen, and are printed out on the recorder trace (Monitoring Maternal Temperature on page 249). SpO2 Recordings and Transmissions SpO2 annotation on local recorder You can now configure the interval for printing the SpO2 numeric values on the recorder trace. With the new configuration setting Record on Trace, you can set the interval to 1 or 5 minutes. SpO2 transmission to an obstetrical information and surveillance system You can now configure the interval for transmitting the SpO2 numeric values to an obstetrical information and surveillance system. With the new configuration setting Send to OB Sys, you can set the interval to 1 or 5 minutes. New Design for the User Interface The user interface for the fetal monitors has been redesigned to bring the presented information into the foreground, letting the structural elements such as keys and frames retreat into the background. Additionally special regard was given to making the "look and feel" similar to that of standard software products (see Operating and Navigating on page 38). New SmartKeys The Start ECG SmartKey and menu item is renamed to Record ECG. With the Call Patient SmartKey, you can now page patients who are ambulating wearing Avalon CL transducers. With the Tele Info SmartKey, you can call up the Tele Info window on the fetal monitor display. In the Tele Info window, you can control and view the status of the cableless transducers from the connected Avalon CL base station. With the Enter Temp SmartKey, a pop-up window opens showing a numeric pad for entering manually measured maternal temperature values. With the NBP Modes SmartKey, you can access the NBP Mode selection and setup, and can directly start and stop a measurement. With the QuickAdmit SmartKey, you can quick admit a patient to the monitor. All new SmartKeys are optional, and have to be configured in Configuration Mode for use (see SmartKeys on page 42). Coincidence INOP Tone When the cross-channel verification detects that the signal of the maternal heart rate coincides with the fetal heart rate, the Coincidence INOP is now issued with a tone at the fetal monitor. The Coincidence INOP tone has a configurable delay see Cross-Channel Verification (CCV) on page 159. 24 2 What's New Increased Internal Back-up Memory The internal back-up memory is now able to store traces and data from at least the last 3.5 hours with the software revision J.3, and minimum 7 hours with the new mainboard hardware revision A 00.18
(see Manually Recording Stored Data on page 258 and Recovering Data on page 257). Dual System Interface Support If the fetal monitor is connected via a LAN connection to OB TraceVue/IntelliSpace Perinatal, the RS232 interface can be used independently to connect e.g. an EMR system on read-only basis. The system connected to the RS232 interface in this case cannot alter any data (such as ADT data, or the date and time setting), or interfere with functions of the monitor, but is able to read output data. The obstetrical information and surveillance system connected via LAN has priority. USB Interface An optional USB interface allows the use of bar code readers and input devices such as a keyboard, or mouse (see Getting to Know Your Avalon FM20/FM30/Bottom on page 32 and Getting to Know Your Avalon FM40/FM50/Rear on page 33). Flexible Nurse Call Interface An optional Flexible Nurse Call interface allows the connection of a nurse call device to the fetal monitors (see Getting to Know Your Avalon FM20/FM30/Bottom on page 32 and Getting to Know Your Avalon FM40/FM50/Rear on page 33). DHCP Support The DHCP support offers an alternative to BOOTP. DHCP (Dynamic Host Configuration Protocol) enables the fetal monitors to request an IP address (internet protocol address) from the connected network (OB TraceVue/IntelliSpace Perinatal) automatically. Data Export Support You can now export measurement values from the monitor to other devices via the LAN interface, or with the optional MIB RS232 interface (see Getting to Know Your Avalon FM20/FM30/Bottom on page 32 and Getting to Know Your Avalon FM40/FM50/Rear on page 33). NBP Configurable Measurement Sequence Up to four measurement cycles can be set up which will run consecutively. For each cycle, you can set the number of measurements and the interval between them. By setting the last cycle to run continuously, you can have regular measurements continue after the sequence has run (see Enabling Sequence Mode and Setting Up the Sequence on page 240. Alarms Enhancements In addition to the standard cyan INOPs, some INOPs can now be configured as red or yellow INOPs to provide a severity indication (ECG Leads Off, Cuff Overpress, Cuff NotDeflated, Battery Empty, No Pulse) (see Alarms on page 117). 25 2 What's New Alarm Reminder In Configuration Mode, you can set now an Alarm Reminder. The Alarm Reminder emits an audible reminder of alarm conditions that remain active after the alarm is acknowledged. This reminder may take the form of a repetition of the alarm tone for a limited time, or an unlimited repetition of the alarm tone (this is the same as a new alarm). The interval between silencing the alarm and sounding the reminder tone can be set to one, two, or three minutes (see Alarm Reminder on page 122). Auto Free In Configuration Mode, you can now set an Auto Free setting which discharges a patient automatically when the fetal monitor has been powered off, or is in standby mode for a set time. Only the demographic patient data is deleted, the trace data is not affected. 26 3 3Basic Operation This chapter gives you an overview of the monitor and its functions. It tells you how to perform tasks that are common to all measurements (such as entering data, switching on a measurement, changing some monitor settings, and setting up the recorder). The alarms section gives an overview of alarms. The remaining sections tell you how to perform individual measurements, and how to care for and maintain the equipment. 27 3 Basic Operation Supported Measurements Different measurements for the same physiological parameter may have a different appearance on the trace, due to: variability (HR), averaging, delay, amplitude, or artifacts. Before interpreting the trace, regard the fetal monitor setup and transducers used. The following Fetal measurements are supported:

Disabling Touchscreen Operation 1 2 To temporarily disable the touchscreen operation of the monitor, press and hold the Main Screen permanent key for about three seconds. A red padlock will blink on the Main Screen permanent key. Press and hold the Main Screen permanent key again for about three seconds to re-enable the touchscreen operation. Operating Modes Select the Main Setup menu. Select Operating Modes and select a mode. When you switch on the monitor, it starts up in Monitoring Mode. To change to a different mode:
1 2 Your monitor has four operating modes. Some are passcode protected. Mode Description Password Protected no yes Monitoring Mode Demo Mode The Monitoring Mode is the normal operating mode to monitor patients. You can change elements such as alarm limits. When you discharge the patient, these elements return to their default values. You cannot select or change grayed out items. These items are for your information only. To change these items, switch to the Configuration Mode. The Demo Mode is used for demonstration and training purposes. Do not change into Demo Mode during monitoring. When transducers are connected to the monitor and the recorder is on, a demo trace is recorded. But the demo trace is not transmitted when the fetal monitor is connected via RS232 to an information and surveillance system such as OB TraceVue/IntelliSpace Perinatal. 44 3 Basic Operation Mode Description Configuration Mode Service Mode The Configuration Mode is for personnel trained in configuration tasks. You can change and store the default values and patient profiles permanently in the Configuration Mode. These tasks are described in the Configuration Guide. During installation, the fetal monitor is configured for use in your environment. This configuration defines the default settings you work with when you switch on the fetal monitor. The Service Mode is for trained and authorized service personnel only. Password Protected yes yes A field displayed at the fetal monitor screen indicates if the monitor is in Demonstration Mode, Configuration Mode, or Service Mode. To change to a different mode, select this field. Automatic Screen Layouts Your monitor's preconfigured screen layouts define how measurement information is arranged on the screen. The monitor automatically applies the correct screen layout for the measurements you are monitoring. No user action is required. Connecting or disconnecting transducers, or activating or deactivating a cableless measurement, results in an automatic adjustment of the screen layout. When a measurement is off, its numerics are removed from the monitor's screen. The monitor stops acquiring data and generating alarms for this measurement. If you disconnect a transducer while it is performing a measurement, the monitor issues a disconnect INOP (and in the case of SpO2, replaces the measurement numeric with a question mark). Settings This section describes the various settings available on the monitor. Active Settings What the monitor displays, and the way it operates, is controlled by its settings. They determine sound volume settings, recorder settings, high and low alarm limits and so forth. The "active settings" are the current settings the monitor uses, including any adjustments made by the last user. Active settings are not permanent, but are retained after a loss of mains power. There are also two preconfigured default settings:
User Default Factory Default 45 3 Basic Operation User Default The User Defaults are a complete configuration stored in the monitor's long-term memory. You can store the active settings, modified to your preference, in the User Defaults (in Configuration Mode). In Monitoring Mode, you can load the User Defaults settings to return to your preferred settings:
1 Select the Defaults SmartKey. 2 Select Confirm in the dialog box to load the User Defaults. Factory Default The Factory Defaults is a complete configuration predefined at the factory. You cannot modify it. In Configuration Mode, you can load the Factory Defaults as the active settings. CAUTION This resets all settings to factory defined values, but be aware that some values will differ from those with which the fetal monitor was originally shipped from the factory (recorder speed and paper scale type will need to be corrected, for instance). After loading the Factory Defaults, check the settings, and if necessary, change them to the settings you normally use. You can use the Factory Defaults as the basis for producing your User Defaults. See the Configuration Guide for details. Global Settings General monitor configuration settings are stored in the Global Settings. These include settings for line frequency, QRS type, and whether the monitor is automatically reset to the User Defaults after a power interruption of more than one minute. You can change the Global Settings in Configuration Mode. Changing Measurement Settings Each measurement has a setup menu in which you can adjust all of its settings. You can enter a setup menu:
1 with the measurement numeric - select the measurement numeric on the screen to enter its setup menu. For example, to enter the Setup FHR1 menu, select the FHR1 (fetal heart rate 1) numeric. 2 with the Main Setup SmartKey - if you want to set up a measurement when the measurement is switched off, use the Main Setup SmartKey and select Measurements. Then select the measurement name from the pop-up list. With this SmartKey you can access any setup menu in the monitor. This guide always describes the entry method using the measurement's setup menu. You can use the method you prefer. 46 Changing Monitor Settings To change monitor settings such as brightness, or touch tone volume:
1 Enter the Main Setup menu. 3 Basic Operation 2 Select the setting you want to change, or select User Interface to enter a sub menu where you can change user interface settings. Adjusting the Screen Brightness 1 Enter the Main Setup menu. 2 3 4 Select User Interface. Select Brightness. Select the appropriate setting for the screen brightness. 10 is the brightest, 1 is the least bright. Optimum is suitable for most situations. Adjusting Audio Volume Here you can adjust the audio volume for Alarm Volume, QRS Volume, and Timer Volume. To adjust an audio volume:
1 Enter the Main Setup menu. 2 3 Select User Interface. Select Audio Volumes, then select one of the volume types, and select an audio level. 10 is the loudest and 1 is the quietest. Selecting zero switches the volume off. Setting the Date and Time The current date and time is displayed in its own element in the information line of the monitor screen. 1 Select the date and time screen element from the monitor's information line to enter the Date, Time menu. Select, in turn, the Year, Month, Day, Hour (in 24 hour format), and Minute, as necessary. Select Store Date, Time to change the date and time. 2 3 WARNING Do not change the date and time setting, if the fetal monitor is connected to a Philips OB TraceVue/
IntelliSpace Perinatal system. The monitor uses the OB TraceVue/IntelliSpace Perinatal system date and time, including daylight saving time changes. As long as the fetal monitor is connected to the OB TraceVue/IntelliSpace Perinatal system via the LAN-setup (locomotive symbol displayed on the monitor's screen), the option to change the date and time settings at the fetal monitor are disabled, this is not valid for RS232 connections, or the connection to other systems. 47 3 Basic Operation When disconnected from AC power, the monitor retains the date and time setting for at least two months. If the monitor is off longer than two months, and the operating system detects that the date and time settings are invalid, the monitor initiates a "cold" start and sets the date to 1 Jan 1997 and the time to 00:00. Checking Your Monitor Revision 1 2 Select Main Setup, Revisions to open the Monitor Revision menu. From the Monitor Revision menu, select the monitor component for which you need revision information. Preparing to Monitor Confirm fetal life before you begin fetal monitoring. Familiarize yourself with the basic operation principles before you start to monitor. CAUTION Check the fetal monitors housing for damage before you start to monitor as part of your safety precautions. After you switch on the monitor:
1 Check that you have the correct patient cables and transducers plugged in for the measurement you want to monitor. If you use an Avalon CL or Avalon CTS system, check if the cableless transducers are ready and charged (apparent by either a lit up green or yellow LED indicator). 2 3 Admit your patient to the monitor (see Admitting a Patient on page 147). 4 Check that the alarm limits, alarm and fetal heart rate volumes, patient category, and so forth, are appropriate for your patient. Change the settings if necessary. 5 Refer to the appropriate measurement section for details of how to perform the measurements you require. Start recording. 6 There is no special emergency access for the Avalon Fetal monitors. For all clinical use cases according the Intended Use, the monitors are taken into operation by connecting them to AC mains and by switching them on. Switching On: FM20/FM30 1 Connect the monitor to AC mains and switch the monitor on. The green power-on LED lights up. The monitor performs a self-test as it starts up. Selftest: OK, the serial number, and revisions for the software and firmware are printed on the fetal trace paper (if recorder Auto Start is configured to On). The monitor display comes on. There is a start-up tone from the loudspeaker. Battery Option If this option has been chosen, the green power-on LED on both the external power supply and the battery LED indicator will light up. 48 3 Basic Operation Switching On: FM40/FM50 1 Connect the monitor to AC mains. 2 The green LED lights up. Press the On/Standby switch. The monitor performs a self-test as it starts up. Selftest: OK, the serial number, and revisions for the software and firmware are printed on the fetal trace paper (if recorder Auto Start is configured to On). The monitor display comes on. There is a start-up tone from the loudspeaker. Adjusting the Display Angle (FM20/FM30) You can tilt the display on the FM20 and FM30 to one of five different positions, or you can fold it completely down. The tilt/fold mechanism works on a one-way ratchet system. You hear a click as each of the five positions is reached. The screen can be folded back down only after tilting the display forwards as far as it will go. To tilt the display from the folded position:
1 Unlock the display by releasing the catch. 2 Lift the display forward. You will hear a click as the first position engages. If you want to tilt the display further, lift the display further forward until you reach the desired angle. 49 3 Basic Operation 3 To fold the display, pull the display forwards as far as it will go. 4 Then push the display all the way back until it clicks shut. If your monitor is wall-mounted, the display should be folded flat. Fastening Belts and Transducers You can use more than one belt if, for example, you are monitoring uterine activity and FHR simultaneously. There are two basic ways to fasten belts and transducers:
Velcro belts together with the butterfly belt clip. Belts with button fixings. What You Need Toco MP or CL Toco+ MP transducer Ultrasound transducer Ultrasound gel Transducer belt (and optional butterfly belt clip, if applicable) 50 3 Basic Operation Using Belts with Button Fixings 1 2 3 Place the transducer belt across the bed, so that the fixing button will face away from the mother when it is fastened. Lie the patient on the bed and arrange the belt around her until it is tight but still comfortable. Fasten the belt by pushing the fixing button through the overlapping section of the belt. Ensure that the fixing button and the loose ends of the belt are at the patient's side. 4 When you have positioned a transducer satisfactorily, you can attach it to the belt by pushing the belt button on the transducer through one of the holes in the belt. 51 3 Basic Operation 5 Alternatively, attach the butterfly belt clip to the transducer belt button and use this to attach the transducer to the belt. The clip allows you to slide the transducer for easy repositioning. Using Belt with Velcro Fixings Insert one end of the belt between the belt guides on one side of the butterfly belt clip, and secure with the velcro fixing. Insert the other end of the belt between the belt guides on the other side of the butterfly belt clip, adjust for the correct tension, then secure with the velcro fixing. 1 Velcro fixing 2 Belt guides 3 Velcro fixing WARNING When connecting devices for acquiring measurements, always position cables and NBP tubing carefully to avoid entanglement or potential strangulation. 52 3 Basic Operation Repositioning Transducers A patient possibly wears transducers for long periods without interruption. In rare cases, skin irritations may occur if a transducer is attached to one location for a longer period. To ensure there are no adverse effects on the patient's skin, inspect the transducer application site at least every three hours. If the skin quality changes, move the transducer to another site. The ultrasound transducer is often repositioned to follow the fetal heart as part of the normal monitoring process, but this is not so for the Toco transducer. Therefore, remember to check its application site (between contractions) at least every three hours. To reduce the risk of skin irritations, do not allow a cleaning or disinfecting agent to remain on the transducer. Follow all instructions that accompany the specific cleaning and disinfecting agents you are using. Remove agent residues with a cloth dampened in water before applying a transducer to a patient. See Care and Cleaning on page 261 for further information, and a list of approved agents. Connecting a Transducer to the Monitor SpO2 socket 1 2 Noninvasive blood pressure socket 3 Fetal sensor sockets You can plug a fetal transducer, an ECG/IUP patient module, an Avalon CL or Avalon CTS Cableless Fetal Transducer System interface cable (red connector), or an external event marker into any of the four fetal sensor sockets marked by the fetal symbol, or "Fetal Sensors" (depending on geography). For measuring maternal SpO2, connect the sensor to the socket marked with the SpO2 symbol or "SpO2" (depending on geography). For maternal noninvasive blood pressure, connect the cuff to the socket marked with the NBP symbol or "NBP" (depending on geography). 53 3 Basic Operation For the FM20 and FM30, you can connect an Avalon CL or Avalon CTS Cableless Fetal Transducer system interface cable (red connector) to one of the fetal sensor sockets at the left side of the monitor. For the FM40 and FM50, you can connect an Avalon CL or Avalon CTS Cableless Fetal Transducer System interface cable (black connector) to one of the two dedicated black sockets marked "Tele" at the rear of the monitor, as an alternative to using one of the fetal sensor sockets (red connector) at the front. 1 Interface cable to Avalon CL and Avalon CTS Cableless Fetal Transducer System. 2 Connect the black connector to one of the two black sockets (marked
"Tele") on the rear of the monitor. What You See on the Monitor When you connect a transducer or sensor, the measurement numeric appears on the screen. FM20/FM30 FM40/FM50 Fetal heart rate measurements are labeled in the order in which you plug in the transducers for those measurements. It does not matter which fetal sensor socket you use, as the monitor allocates a channel automatically. For instance, when monitoring triplets, the first transducer you connect is automatically allocated a channel, and the measurement is labeled FHR1, the second FHR2, and the third FHR3. See also chapters Monitoring Twin FHRs on page 183 and Monitoring Triple FHRs on page 191. When you touch a measurement numeric on the screen, the setup menu for that measurement opens. The fetal sensor socket to which the transducer for this measurement is connected is identified by the transducer position indicator in the setup menu header. 54 3 Basic Operation The blue finder LED on a wired fetal transducer lights up when you touch the measurement on the screen, allowing you to identify the corresponding transducer. 1 finder LED The white finder LED on a cableless fetal transducer lights up when you touch the measurement on the screen, allowing you to identify the corresponding transducer. 1 finder LED cableless transducer The recorder prints an annotation showing the date, time, recorder speed, and Monitoring Mode. It repeats this every 10 minutes. Start Recording Checking/Setting Paper Scale You can check the paper Scale Type (US for USA, or Internat'l for other geographies) in the Fetal Recorder menu. In Monitoring Mode, you can see these settings (grayed out), but you cannot change them. They can be changed in Configuration Mode, see the Configuration Guide. NOTE Check if the scale type of the paper and the settings in the fetal monitor match. 55 3 Basic Operation Paper Guide FM40/FM50 The recorder in the FM40 and FM50 features a transparent paper guide which:
facilitates correct alignment of the paper, both during loading and while the recorder is running. See Loading Paper FM40/FM50 on page 65. incorporates a tear-off edge, which not only allows you to tear off the trace paper where you like
(not necessarily at a fold), but also helps to avoid paper misalignment while doing so (see Tearing Off the Paper on page 61). is removable (see Removing the Paper Guide: FM40/FM50 on page 269). Switching the Recorder On and Off In addition to the normal recording of real-time traces, you will sometimes see a trace recovery printout from the monitor's internal backup memory at high speed when the recorder is started. For details, see Recovering Traces on Paper on page 257. For an explanation of the various symbols that can appear on the trace recording, see Recorder Specifications on page 308. To switch the recorder on, select in Main Setup the menu item Fetal Recorder, or press one of the SmartKeys: Start/ Stop or Start Recordng. The "recorder on" status indicator is displayed in the bottom right-hand corner of the screen when you switch on the recorder. The paper advances quickly for 2 cm and then returns to the set speed. Whenever the recorder is switched on, a trace header is printed vertically on the trace paper, containing the following:
Selftest: OK: confirmation that the monitor's self-test completed successfully, and that it is ready to use the software revision and firmware revision the serial number the time the date patient name and medical record number (if entered) the recorder speed 56 3 Basic Operation 1 Fetal heart rate label 2 Uterine activity label the time the date trace identification symbols the recorder speed The current monitoring modes (if any transducers are connected to the monitor) are printed. Whenever a transducer's mode is changed, the following are printed:
The monitor prints the time, date, recorder speed, and monitoring modes in the trace header when first switched on, in a periodic time stamp every ten minutes after, and if the monitoring modes change. The time stamp begins with the symbol shown below. The data is reprinted in the header if the time and date are locally adjusted, or if an obstetrical information and surveillance system is connected that readjusts the time and date automatically. 57 3 Basic Operation 1 Time stamp printed every ten minutes The trace records maternal parameters also. When measuring noninvasive blood pressure, the annotation is made at the end of the measurement. If the noninvasive blood pressure measurement repetition time is short, the noninvasive blood pressure numeric may not always be printed. The recording of notes (see Entering Notes on page 69) or time/date information may be interrupted by connecting, or unplugging a transducer, or by a change in measurement-related setting
(for example, artifact suppression, Toco sensitivity, or alarm settings). A new patient admission or a change to the paper scale setting stops all annotations, and prompts a new vertical trace header to be printed. To switch off the recorder:
1 Either select Start/Stop from the Fetal Recorder menu. 2 Or press one of the SmartKeys (depending on configuration): fetal recorder Start/ Stop or Stop Recordng. If your recorder is configured with Confirmed Stop on (a Configuration Mode setting), you will need to confirm that you want to stop the recorder, before it will stop. When the recorder is off, the "recorder off" status indicator is displayed in the bottom right-hand corner of the screen: When the Paper Save Mode is set to Off the paper symbol shows an x mark, and when Paper Save Mode is On the icon shows a paper trace icon. 58 Recording Elements A variety of information can appear on the recorder trace. Here is a sample trace with some of the most common elements and their meaning. Each trace header contains the last name and first name, the patient ID, patient date of birth, the current date and time, patient's bed label, and the gestational age of the pregnancy. 3 Basic Operation FMP - Fetal Movement Profile 1 Name, patient ID, date of birth, current date and time 2 Recorder speed 3 Gestational age and patient bed label 4 5 Other measurements for the patient such as temperature, arterial oxygen saturation, and pulse 6 Entered notes such as patient repositioned, or MD notified, or others 7 Time stamp 8 Trace separation 9 Recorder speed 10 Maternal ECG 11 Direct ECG 12 Coincidence of heart rate detected 13 HR with Alarms Off symbol 14 Alarm Limits 15 dFHR2 (second fetal heart rate from DECG) 16 FHR1 (first fetal heart rate) 59 3 Basic Operation Caution The trace contains sensitive personal data. For information how to protect personal information, see Protecting Personal Information on page 17. Choosing Recorder Speed You can choose a recorder speed of 1, 2, or 3 centimeters per minute (cm/min). The default setting is 3 cm/min. The ACOG technical bulletin on FHR monitoring states that "accurate pattern recognition is difficult if not impossible at 1 cm/min and that 1 cm/min is only recommended for more economic screening. When FHR abnormalities arise, the faster recorder speeds will enhance FHR pattern recognition". Additionally, because a change in recorder speed results in a change in the appearance of an FHR trace, you are advised to ensure ALL monitors in your institution are set to the same speed. To set the recorder speed (in Configuration Mode), see the Configuration Guide. Advancing the Paper You can advance the paper automatically to the next fold by pressing the Paper Advance SmartKey at any time except during a stored data recording. This is also possible using the Fetal Recorder menu. Marking an Event You can record significant events on the trace paper (for example, when pain medication is administered or when the mother changes position). The mother can use the remote event marker to mark events herself. You connect the remote event marker to any free fetal sensor socket. To mark an event on the trace paper, you can:
1 Either select the Set Marker SmartKey. 2 Or press the button on the optional remote event marker (989803143411). The remote event marker is connected to the monitor via any fetal transducer socket. 60 A small arrow is printed on the heart rate scale on the trace paper. 3 Basic Operation This reflects exactly when the marker button was first pressed; keeping the button pressed has no influence on the annotation. Tearing Off the Paper CAUTION Never pull on the paper to advance it, as this can cause misalignment of the paper. Always tear off the paper along the perforation. FM40/FM50 The recorder's paper guide incorporates a tear-off edge, allowing you to tear off the trace paper cleanly where you like (not necessarily at a fold). When you are not using the paper guide, always tear off the paper along the perforation. To tear off the trace paper after monitoring using the paper guide:
1 If the recorder is running (the "recorder on" status indicator is displayed), turn off the recorder by selecting the fetal recorder Start/ Stop SmartKey or the Stop Recordng SmartKey. 2 Tear off the paper as shown in the picture. To ensure a clean tear, always tear in an upwards motion, as indicated by the arrows. You can start tearing from the left or right (right-handed user 61 3 Basic Operation shown). You may want to use both hands to guarantee that the paper is not misaligned during the tear off. 3 If you wish to tear off the paper at a fold, select the Paper Advance SmartKey, wait for the paper to stop, then tear it off. FM20/FM30 The FM20/FM30 does not have a paper guide. The procedure is the same as described for the FM40/
FM50 with the exception that you should advance the paper to a perforation. If you wish to tear off the paper at a perforation, select the Paper Advance SmartKey, wait for the paper to stop, then tear it off. Paper-Out Indication Each pack of paper has 150 pages. The monitor issues a paper-out warning in the status line at the bottom of the screen, when there are five pages to go. If you switch on the recorder or press the Paper Advance key when there are fewer than five pages remaining, it may take two pages before the alarm is activated. Load a new pack in time. If the recorder runs out of paper, an audible paper-out alarm is sounded, if so configured. See Loading Paper FM40/FM50 on page 65, and Loading Paper FM20/FM30 on page 62 to learn how to reload paper. Fetal traces continue to be recorded into the monitor's backup memory, and can be retrieved and printed completely if new paper is loaded within one hour, when the Bridge Paperout setting is enabled in Configuration Mode. See Recovering Traces on Paper on page 257 for further information. Loading Paper FM20/FM30 CAUTION Using recorder paper that is not approved by Philips can result in accelerated paper fading and can damage the thermal line printhead. This type of damage is not covered by warranty. 62 FM20/FM30 To load a pack of paper:

It is held in the closed position by a small protrusion on each side of the holder. A - Protrusion holds paper guide in closed position. 66 3 Basic Operation 6 Prepare to place the new pack of paper in the tray with the bottom side down. The bottom side is indicated by the word STOP printed on the final page of the new pack. 7 Unfold the top page of the pack and position the uterine activity scale on the right. 8 Slide the pack into the tray. 9 Feed the paper evenly through the paper guide. Do not close the paper guide yet. 67 3 Basic Operation 10 Close the paper drawer. 11 Now close the paper guide. 12 Press the recorder Start/ Stop SmartKey or the Start Recordng SmartKey to switch on the recorder. Annotations of trace information are printed on the trace paper (see Switching the Recorder On and Off on page 56 for details). 68 3 Basic Operation Entering Notes Your monitor has a set of 15 factory pre-configured notes (see below). It is possible to edit these notes in Configuration Mode (see the Configuration Guide). The maximum length of one single note is 30 characters. To enter a note:
1 Select the Enter Notes SmartKey to open the Enter Note menu. 2 3 Scroll if necessary, then select the note you wish to enter. A confirmation dialog box opens:
Select Confirm to enter the note. The note is then shown in the status line of the display, and is annotated on the fetal trace if the fetal recorder is on. 4 By default, notes are printed lengthwise in the direction of the trace, in the space between the FHR grid and the uterine activity grid. If you prefer, you can configure the recorder to print across the trace. You can change this in Configuration Mode. Patient Repositioned Vaginal Examination Left Lateral Ambulating Tocolytic Given The following are the pre-configured notes from which to choose:
1 2 3 MD Notified 4 Sitting 5 On Back 6 7 8 9 Membranes Ruptured 10 Amniotomy 11 Amniotic Fluid Clear 12 Amniotic Fluid Not Clear 13 Oxytocin 14 Urinary Catheter 15 Micro Blood Analysis Up to two notes can be printed directly, and the monitor can temporarily store up to a further two notes, and these are printed after the first two have been printed. Any further notes are discarded. For example, if you enter six notes in quick succession, the first two notes you entered are printed right away, the next two are stored in memory and then printed when the first two have been printed, and the last two are discarded. If the printing of two notes happens to coincide with the regular printing of the time stamp that takes place once every ten minutes, the time stamp is delayed until the notes have finished printing. 69 3 Basic Operation Typing Notes Other than the pre-configured notes selectable in the Enter Note menu, a note can be typed in manually. To type a note:
1 Select the Enter Notes SmartKey to open the Enter Note menu. Select Type a note and a window with a touch keypad opens. 2 3 Type the note and select Enter. The typed note can be up to 30 characters long. The note is shown in the status line of the display, and is annotated on the fetal trace if the fetal recorder is on. NOTE The typed note remains in the window until it is deleted by using the backspace button of the keyboard. Signal Quality During monitoring, if the fetal heart rate signal quality fluctuates, and becomes poor, it does not necessarily mean that the transducer needs repositioning. The fluctuation may be caused by fetal movement. Allow time for the signal to stabilize before deciding whether to reposition the transducer
(ultrasound), or apply a new electrode (ECG). For the best trace quality, the signal quality indicator should be full, indicating good signal quality, even though it may be possible to make traces at a lower signal quality level. After Monitoring Wired and cableless transducers 1 Discharge the patient. 2 Remove the transducer from the patient and, using a soft tissue, remove any gel from it. Then clean the transducers. 3 Dock CL transducers to the base station so they can recharge. 4 Tear off the paper at the fold. To avoid misalignment of the recorder mechanism, NEVER pull on the paper to advance it, or try to tear it other than at a fold (unless using the paper guide with the FM40/FM50). Switch off the monitor. 5 NOTE If an Avalon CL base station is connected to your FM20/30 monitor, do not turn off the monitor if you need to recharge the batteries of the CL transducers. They can only be recharged if the FM20/30 monitor is on. If an Avalon CL base station is connected to an FM40/50 at the Telemetry ports in the rear, the batteries of the CL transducers can be recharged while the monitor is not switched on. If you disconnect a base station from a fetal monitor when the CL transducers are not fully charged, the base station starts beeping. If you want to still disconnect it, confirm your choice by pressing the Standby key of the base station, and the beeping stops. 70 Switching the Monitor to the Standby Screen 3 Basic Operation To switch the monitor to the Standby screen:
Either 1 Select the Monitor Standby SmartKey. Or 1 Enter the Main Setup menu using the SmartKey. 2 3 Select Monitor Standby. Pressing any key or selecting any field on the screen will resume monitoring. Disconnecting from Power FM20/30 To disconnect the monitor from AC power, switch the monitor off using the On/Off switch located on the right side of the device, or unplug the power cord from the AC mains socket. FM20/FM30 with Battery Option and FM40/FM50 The On/Standby button does not disconnect the monitor from the AC power source. To disconnect, unplug the power cord from the AC mains socket. Note that if the power cord is unplugged from the AC mains socket before the monitor is put into Standby, a beeper is activated. The beeper warns you if the monitor is accidentally disconnected from AC mains. External Power Supply for the Avalon CL Base Station To disconnect, unplug the power supply from the AC mains socket. Note that if the power supply is unplugged from the AC mains socket before all CL devices are fully charged, a beep is issued. To confirm the disconnection from power, and to silence the beep, press the On/Standby button of the CL base station. Power On/Power Off Behavior The general rules determining the behavior of the fetal monitors when connected to, or disconnected from power are as follows:
A fetal monitor that was switched on prior to a temporary power loss, switches on again when power is restored. A fetal monitor that was switched off prior to a temporary power loss, remains off when power is restored. When AC mains power is lost, a battery powered monitor (FM20/30) continues to run without interruption on battery power. 71 3 Basic Operation Monitoring After a Power Failure A fetal monitor that was switched on prior to a temporary power loss, switches on again when power is restored. A fetal monitor that was switched off prior to a temporary power loss, remains off when power is restored. If the fetal monitor is without power for less than one minute, monitoring will resume with all active settings unchanged. If the fetal monitor is without power for more than one minute, the behavior depends on your configuration. If Automat. Default is set to Yes, the default profile will be loaded when power is restored. If Automat. Default is set to No, all active settings are retained, if power is restored within 48 hours. The Automat. Default setting is made in Configuration Mode. Troubleshooting Problem Light or no trace Possible Causes Wrong paper Dirty printhead FM20/30 only: Paper misaligned due to drawer not being correctly shut Bad paper feed or wrong paper INOP messages always indicate equipment problems End of paper noted when pack not finished Check Paper INOP is displayed FetRec Equip Malf INOP is displayed Paper End INOP is displayed Wrong Paper Scale INOP is displayed Solutions Use recommended paper Clean printhead, see Cleaning the Print Head on page 273 Shut the drawer fully, pushing evenly with both hands Check paper feed and use recommended paper See Patient Alarms and INOPs on page 129 72 4 4Cableless Monitoring Avalon CL Transducer System The Avalon CL Fetal Transducer System lets you monitor the patient continuously with cableless transducers during the antepartum period, labor, and delivery. You can monitor the fetal heart rate (FHR):
Using noninvasive CL Ultrasound transducers Invasively, using the CL ECG/IUP transducer or CL Toco+ MP transducer with a fetal scalp electrode Invasively, using the CL ECG/IUP transducer or CL Toco+MP with an IUP catheter Noninvasively, with the CL F&M Pod The uterine activity can be monitored using:
Externally, using the CL Toco+MP transducer Externally, using the CL F&M Pod The fetal and maternal parameters are measured and transmitted via radio frequency from the CL transducers and CL Pods to the CL base station, eliminating the need for patient cables. With the Avalon CL Transducer System, you can monitor a single fetus, twins, and triplets. The Avalon fetal monitor (FM20-FM50) connected to the CL base station displays and records the parameters. All the CL transducers and the CL F&M Pod are watertight. The IntelliVue CL Pods should not be immersed in water. You can continuously monitor patients in a bath or shower using the CL Toco+MP and the CL Ultrasound transducers, the CL F&M Pod should not be used during a bath. 73 4 Cableless Monitoring Basics of Cableless Systems Avalon CL Transducer System Avalon CTS Transducer System Assigning Cableless Devices The cableless devices of the Avalon CL are assigned by simply docking them at the base station connected to the patients fetal monitor. See the Avalon CTS Instructions for Use for the assignment of the CTS transducers. Activating Cableless Devices The CL devices of the Avalon CL are activated by picking them up from the base station. If the CL devices are activated, a corresponding symbol is displayed on the fetal monitor screen next to the numeric of the measurement. See the Avalon CTS Instructions for Use for the activation of the CTS transducers. Deactivating Cableless Devices The CL devices of the Avalon CL are deactivated by redocking them at a base station. To deactivate all cableless devices at once, press the Standby key of the Avalon CL base station. See the Avalon CTS Instructions for Use for the deactivation of the CTS transducers. Unassigning Cableless Devices The CL devices of the Avalon CL are unassigned by manually removing them in the corresponding setup menu from the group of assigned cableless devices, or by unassigning them directly in the Tele Info window. See the Avalon CTS Instructions for Use for the unassignment of the CTS transducers. 74 4 Cableless Monitoring Twins and Triplets Support Twins and Triplets Avalon CL Transducer System and CL transducers Singletons only Avalon CTS System Avalon CL Transducer System with CL Fetal & Maternal Pod Configuration of Cableless Systems You have to configure the radio channels of the Avalon CL and Avalon CTS transducer system for communication to work, and not to interfere with any other telemetry devices. The configuration of a connected Avalon CL system is done in Configuration Mode or Service Mode of the fetal monitor. Service Mode functions can be used to identify channel assignment conflicts in the hospital environment. The configuration should be carried out by authorized and qualified service personnel, either by the hospital's biomedical department, or by Philips Support. For a detailed description of the configuration see the Avalon CL Service Guide and the Fetal Monitor Configuration Guide. For details regarding the configuration of a connected Avalon CTS system see the Avalon CTS Service Guide. Fetal Movement Profile When using an Avalon CL or Avalon CTS you should be aware that monitoring FMP is not recommended when the mother is likely to move, and you should disable Fetal Movement Profile
(FMP) on the fetal monitor (Fetal Movement Off) if the mother is walking. Maternal movements are likely to create artifact in the FMP output. See also Switching FMP On and Off on page 171, the sections Cableless Monitoring - Important Considerations on page 167, and Fetal Movement Profile on page 170. 75 4 Cableless Monitoring Getting to Know Your Avalon CL Front Transducer docking slots 1 2 On/Standby button with LED 3 Device label 4 LED for optional cableless Pods 5 Docking slot for cableless Pods WARNING To avoid magnetic interference affecting the mode of the pacemaker, ensure that the Avalon CL base station does not come into close contact with implanted pacemakers. This equipment generates, uses, and radiates radio-frequency energy, and if it is not installed and used in accordance with its accompanying documentation, may cause interference to radio communications. Operation of this equipment in a residential area may cause interference, in which case you must take whatever measures may be required to correct the interference. 76 Docking Slots for Cableless Transducers The Avalon CL base station has three docking slots to hold the CL transducers. The transducers are charged while docked. The base station has a built-in radio interface with an integrated antenna to communicate with the transducers. 4 Cableless Monitoring On/Standby Button Pressing the On/Standby button switches the Avalon CL base station between the two modes On and Standby. 1 On/Standby button If you switch the base station to On, the LED button lights up green. The base station is ready for use. When the transducers are picked up from their docking slot, the base station sets up the radio communication to the CL transducer automatically. Wired transducers connected to the fetal monitor are disabled, and the antenna symbol for the CL transducer is displayed on the screen of the fetal monitor. If you switch the base station to Standby, the LED button turns off. The base station is now in Standby mode. No radio communication occurs, any existing radio communication is stopped. If the LED of the On/Standby button turns red, it indicates a technical problem has occurred that needs your attention. Check your monitor for a possible related INOP message. 77 4 Cableless Monitoring Docking Slot for Cableless Measurement Pods The Avalon CL base station has one docking slot to hold a CL F&M Pod or an IntelliVue CL Pod. The CL Pod is charged while docked. The LED under the docking slot indicates the battery status of the CL Pod. The base station has a built-in short range radio interface with an integrated antenna to communicate with the CL Pod. 1 Docking slot for CL Pods WARNING Short range radio connections are subject to interruption due to interference from other radio sources in the vicinity, including microwaves, bluetooth devices, WLAN devices (802.11b,g,n), and cordless phones. Depending on the strength and duration of the interference, the interruption may occur for an extended period. A loss of connection, due to moving out-of-range, interference, or for other reasons, is indicated with a No Host Monitoring INOP (here the host is the fetal monitor) on the NBP or SpO2 Pods, or a cl NBP Disconnect or cl SpO Disconnect INOP at the fetal monitor. Correct channel configuration is important, see the Configuration Guide for details. Audio Signal CL Base Station The Avalon CL base station has two audio signals:
If the base station issues a descending tone sequence, the attempt to set up radio communication to a CL transducer or CL Pod has failed. The base station issues a permanent beeping tone if it is disconnected from a fetal monitor, or if the FM20 or FM30 monitor is switched off, and the base station has transducers or a Pod currently docked that need to be recharged. Alarming is only available at the Avalon Fetal Monitor, not at the Cableless Measurement Devices, see the Instructions of Use for the IntelliVue Cableless Measurements. 78 Rear and Bottom 4 Cableless Monitoring 1 Name plate 1 Manufacturer label 2 Cable reel 79 4 Cableless Monitoring Connection Options The fetal monitors FM20/FM30 and FM40/FM50 are compatible with the Avalon CL and Avalon CTS Transducer Systems. Regard the following points for cableless monitoring:
You can connect one Avalon CL base station with a red connector to an FM20/FM30 or an FM40/FM50 (fetal socket), or one Avalon CL base station with a black connector to an FM40/
FM50 (telemetry socket). You can connect two Avalon CL base stations with black connectors to an FM40/FM50
(telemetry sockets) 80 You cannot connect two Avalon CL base stations to an FM40/FM50, if one Avalon CL base station has a red connector, and the other Avalon CL base station has a black connector. 4 Cableless Monitoring You can connect one Avalon CTS system to an FM20/FM30 or FM40/FM50 at a time (either fetal or telemetry socket). 81 4 Cableless Monitoring You cannot connect an Avalon CTS and an Avalon CL at the same time to the same fetal monitor. Monitoring a multiple pregnancy using cableless transducers is supported by the Avalon CL system only. Using a mixture of wired and cableless fetal transducers is not supported. You can use either wired or cableless fetal transducers. If you cannot get sufficient signal quality using Avalon CTS transducers, switch to wired transducers. 82 4 Cableless Monitoring Connecting Two CL Base Stations to an FM40/50 Monitor Two base stations can be connected to an FM 40/50 fetal monitor at the rear black telemetry ports. At both base stations CL transducers and CL Pods can be assigned, activated, and redocked for charging. The base stations work as one extended system together. Pressing the Standby key of either base station, puts both base stations in Standby mode. The Tele Info window shows both base stations in operation. External Power Supply (Option K60) In combination with the optional external AC power supply an Avalon CL base station serves only as a charging station for Avalon CL transducers and IntelliVue CL Pods, and all radio communications are disabled. The On/Standby button of the base station lights up white in this operation mode. The charging indication of the LEDs of the docked CL transducers and the IntelliVue CL Pods remain the same as described in the sections Cableless Transducer LED Indication on page 86 and Battery Status LED for CL Pods on page 93. When a transducer is picked up from the base station after charging, it needs to be activated for monitoring by docking it on a CL base station connected to the patient's fetal monitor. 83 4 Cableless Monitoring Cableless Transducers The cableless Avalon CL transducers have a built-in radio interface with an on-board, integrated antenna. The fetal monitor connected to the Avalon CL base station can control the transducer using radio communication. The CL transducer transmits measured values, alarms, and status information to the fetal monitor. The CL transducers are assigned by simply docking them at the Avalon CL base station. If they are picked up from their docking slot at the base station, they are automatically activated. CAUTION To ensure the correct assignment of CL transducers to the fetal monitor in use, always dock them at the base station connected to that fetal monitor before use. This is particularly important when you add an additional CL transducer that was previously docked at another base station. NOTE Avoid dropping the transducers. 1 Transducer finder LED - lights up on the transducer providing the measurement source. 2 CL Toco+ MP transducers

The connector cap is designed to cover the connector, not to protect it from water. (The connector itself is water-proof and may be immersed in water). 85 4 Cableless Monitoring Cableless Transducer LED Indication The cableless transducers have a multi-color LED that indicates the status of the transducer with specific colors. This LED remains visible when the transducer is correctly attached to the transducer belt (Philips standard belt). 1 LED LED Status White White one short blink Green Yellow Red Cyan Meaning The LED lights up to identify the transducer among other transducers, and to easily verify the correct transducer assignment (transducer finder). The transducer finder LED is controlled by the fetal monitor. Press the numerics to identify the corresponding transducer. The LED also lights up when the mother is paged with the Call Patient SmartKey. The LED shortly lights up to indicate that the transducer successfully opened a radio communication with the base station and that it is ready to use. The LED lights up green when the transducer is fully charged and docked at the base station. The LED lights up yellow when the transducer is charging and docked at the base station. The LED flashes red when the transducer is out of battery and has to be recharged. When a docked transducer performs an update, the LED will blink fast red for about 1 minute. In this case, do not remove the transducer until the LED lights up green or yellow again. The LED lights up cyan to indicate a technical problem that needs your attention. Check your fetal monitor for a related INOP. 86 Audio Signal CL Transducers 4 Cableless Monitoring The Avalon CL transducers have three audio signals:
If an ascending tone sequence is played three times, the transducer was triggered by the fetal monitor to page the patient wearing it, or to locate a not docked transducer. If the CL transducer's battery is empty, the transducer issues three beeps in intervals. An INOP tone indicates that the transducer has detected a technical problem (INOP). Check your fetal monitor for a related INOP message. Standard Radio Range of CL Transducers The CL transducers have an operating range around the base station of at least 100 m/300 ft in the line of sight. Obstructions such as walls, metal doors, elevators, and other environment structures can lead to signal loss. The CL symbol indicator and the Tele Info window on the monitor's display (see Screen Elements on page 39 and Tele Info Window on page 94) provide information on the status of the signal strength. When a patient is approaching the end of range, the US sound is replaced by an artificial QRS sound
(like DECG), and the DECG and MECG waves are no longer displayed on the monitor. Out of Range If the patient walks out-of-range, the CL transducer LED lights up cyan and every 16 seconds a two-
tone audio signal is emitted. At the monitor the INOP e.g. cl US Disconnect is issued. Inform the patient to return to the CL base station, when a CL transducer starts beeping. Radiated Transmission Power The Avalon CL transducers provide all the benefits and flexibility of cableless operation, but do so with an effective radiated transmission power significantly less than that of a typical remote controlled childs toy or mobile phone. Extended Range Radio Using the optional CL Wide Range Pod extends the radio range of the CL transducers and the CL Pods to the local WLAN infrastructure. If the CL Wide Range Pod is active, the US sound is replaced by an artificial QRS sound (like DECG), and the DECG and MECG waves are no longer displayed on the fetal monitor. Numerics, alarms, and traces are shown at the fetal monitor as usual. See also CL Wide Range Pod on page 91. 87 4 Cableless Monitoring Using CL Transducers with a Belt Clip The Avalon CL transducers can also be used with an optional belt clip to be ordered separately
(989803184851). 1 Avalon CL belt clip 88 4 Cableless Monitoring CL Pods CL Fetal & Maternal Pod The CL F&M Pod provides measurement values for FHR, Toco, and HR. It communicates them to the fetal monitor using short range radio (SRR). It is controlled via SRR from the Avalon CL base station and the connected fetal monitor. The CL F&M Pod is assigned by docking it at the Avalon CL base station. Before monitoring, the CL F&M Pod is mounted on a single-use electrode patch, and held in place by integrated magnets. When the CL F&M Pod is active, the wired transducers connected to the fetal monitor are disabled. CL F&M Pod CL F&M Patch WARNING The CL Fetal & Maternal Pod has been validated with a gestational age of >36 weeks with patients in labor. It is only intended for singleton pregnancies. If the measurement signals are not good or in any way suspicious, use other means of monitoring (CL transducers or wired transducers). 89 4 Cableless Monitoring CL Fetal & Maternal Pod LED Indication The CL F&M Pod has a multi-color LED that indicates the status of the CL F&M Pod with specific colors. 1 LED LED Status White White, one short blink Green Yellow Red Cyan Meaning The LED lights up to identify the CL Pod, and to easily verify the correct assignment (finder). The finder LED is controlled by the fetal monitor. Select the numerics to identify the corresponding CL Pod. The LED also lights up when the mother is paged with the Call Patient SmartKey. The LED briefly lights up to indicate that the CL Pod successfully opened a radio communication with the base station and that it is ready to use. The LED lights up green when the CL Pod is fully charged and docked at the base station. The LED lights up yellow when the CL Pod is charging and docked at the base station. The LED flashes red when the CL Pod's battery is empty, and has to be recharged. The LED lights up cyan to indicate a technical problem that needs your attention. Check your fetal monitor for a related INOP. Audio Signal CL Fetal & Maternal Pod The Avalon CL F&M Pod has three audio signals:
If an ascending tone sequence is played three times, the CL F&M Pod was triggered by the fetal monitor to page the patient wearing it, or to locate a not docked CL F&M Pod. If three beeps are issued at intervals, the CL F&M Pod's battery is empty. An INOP tone indicates that the CL F&M Pod has detected a technical problem (INOP). Check your fetal monitor for a related INOP message. 90 4 Cableless Monitoring CL Fetal & Maternal Electrode Patch The single-use disposable adhesive electrode patch holds the CL F&M Pod at the intended application site on the abdomen of the patient. The electrode patch has five adhesive electrodes. The CL F&M Pod is held in place during monitoring with magnetic contacts, and a connector. The electrode patch and the CL F&M Pod can only be used together and within the Avalon Cableless Transducer System solution for monitoring. CAUTION The electrode patch is single-patient use only, do not reuse the electrode patch on another patient to avoid possible cross-infection. CL Wide Range Pod The Avalon CL Wide Range Pod is a battery-powered auxiliary network device that converts the SRR and OB radio technology of Avalon CL transducers and the CL Pods into WLAN technology. This allows data from the measurement devices to be transmitted to a fetal monitor while the patient is ambulating. The Avalon CL Wide Range Pod is a mobile device which can be worn by the patient or by an attending caregiver. The display on the CL Wide Range Pod shows only technical data that may be useful for troubleshooting system problems. CL Wide Range Pod 91 4 Cableless Monitoring IntelliVue CL Pods The two IntelliVue CL Pods provide measurement values for SpO2 and NBP on the built-in display, and communicate them to the fetal monitor using short range radio (SRR). They are controlled with SRR from the Avalon CL base station and the connected fetal monitor. The maternal measurement pods are assigned by docking them at the Avalon CL base station. CL NBP Pod CL SpO2 Pod The CL SpO2 Pod and the CL NBP Pod have an LCD display and three keys for basic operation e.g. to assign the device to a patient:
Integrated LCD display 1 2 Hardkeys 3 Measurement identifier For further details, see the IntelliVue Cableless Measurements Instructions for Use. 92 4 Cableless Monitoring Battery Status LED for CL Pods The CL Pods do not have their own battery status LED, but a small battery gauge on their display. On the Avalon CL base station, the battery status LED for the CL Pods is located directly under the docking slot. 1 Battery status LED for CL Pods The battery status LED shows five different states:
Status Green Yellow Yellow blinking Cyan Meaning The docked CL Pod is fully charged. The docked CL Pod is charging. The communication is established with the docked CL Pod. Indicates that the docked CL Pod or the charging slot has a technical problem that needs your attention. Check your fetal monitor for a related INOP message. The battery status LED is off, when no CL Pod is docked. Off Audio Signal CL Pods The CL Pods have audio signals to let you know when a battery has to be recharged. If a CL Pod's battery is empty, the CL Pod issues three beeps at intervals. Calling Patients To call a patient currently not near the fetal monitor and base station, select the SmartKey Call Patient at the fetal monitor. The base station will then select one transducer, or the CL F&M Pod if it is assigned and active, to emit the tone sequence to notify the patient. Inform the ambulating patient, if the cableless device is issuing any beeping sounds, to return to the room with the fetal monitor. 93 4 Cableless Monitoring Telemetry Tele Info Window The Tele Info window of the fetal monitors allows you to manage the Avalon CL or CTS system. Below is an exemplary view of the Tele Info window. Your window may differ depending on the status of the connected system. To open the Tele Info window, you can:
1 Configure a Tele Info SmartKey to open the window, 2 3 select the CL symbol on the main screen, or select the Main Setup and then Tele Info. 1 CL transducer symbol assigned with the parameter labels 2 Cableless measurement symbol and equipment ID 3 Base station symbol with docking indication (the white slot indicates a charging transducer) 4 Key Remove 5 Key Find 6 Key Battery Report (in Service Mode) 7 CL symbol 8 Remaining battery time 9 Out of battery symbol 10 Indication of radio signal quality 94 4 Cableless Monitoring Cableless Status Indication When the monitor recognizes a connected Avalon CL or Avalon CTS interface cable (red or black connector), it confirms the recognition with the following status indicators displayed in the lower right-hand corner of the screen:
Avalon CTS Indicator Description Avalon CTS interface cable is connected to the monitor, but the Avalon CTS base station is not connected to the interface cable, or it is disconnected from AC mains, or is in Standby mode. Avalon CTS interface cable is connected to the monitor, Avalon CTS base station is connected, powered on, and cableless transducers are ready to use, but no cableless transducers are currently active (all are still docked at the base station). Avalon CTS interface cable is connected to the monitor, Avalon CTS base station is connected, powered on, and at least one cableless transducer is active and assigned. Avalon CL Indicator Avalon CL A base station is connected to the monitor, but the base station is in Standby mode. A base station is connected to the monitor, but the base station is in Standby mode. The CL Wide Range Pod is activated and trying to connect to the monitor. A base station is connected to the monitor, but the base station is in Standby mode. The CL Wide Range Pod is activated and connected to the monitor. A base station is connected to the monitor but no cableless transducers and no cableless Pods are currently active. All are still docked at the base station, or the base station holds no transducers. A base station is connected to the monitor but no cableless transducers and no cableless Pods

The CL Wide Range Pod is activated and connected to the monitor. A base station is connected to the monitor, it is on, and minimum one assigned cableless transducer or cableless Pod is active. 95 4 Cableless Monitoring Indicator Avalon CL A base station is connected to the monitor, it is on, and minimum one assigned cableless transducer or cableless Pod is active. The CL Wide Range Pod is activated and trying to connect to the monitor. A base station is connected to the monitor, it is on, and minimum one assigned cableless transducer or cableless Pod is active. The CL Wide Range Pod is activated and connected to the monitor. A CL transducer has moved away from the base station and is approaching the limit of the area of reach (min. 100 m/300 ft in line of sight). The US sound is replaced by an artificial QRS sound
(like DECG). The DECG and MECG waves are no longer displayed. A CL transducer has moved away from the base station and is approaching the limit of the area of reach (ca. min. 100 m/300 ft in line of sight). The US sound is replaced by an artificial QRS sound
(like DECG). The DECG and MECG waves are no longer displayed. The CL Wide Range Pod is activated and trying to connect to the monitor. NOTE A CL transducer is considered still active, even if it has an INOP condition (e.g. cl US Disconnect), until it is either deactivated by docking it at the base station, or until it is manually removed from the Tele Info window. Pop-up Keys Pop-Up key Remove Find Function Selecting the Remove key deactivates and unassigns the selected active transducer or CL Pod and removes it from the list. This key is disabled if no active device is selected. Selecting the Find key pages the selected active CL transducer. This key is disabled if no active device is selected. Messages The fetal monitor issues messages to certain user interactions. For example, if the CL SpO2 Pod is picked up from the base station to activate it, the monitor displays the message cl SpO Added and the equipment label of the CL Pod. 96 Use Priority When Combining Cableless and Wired Measurements 4 Cableless Monitoring CL Transducers versus wired transducers CL transducers have priority over wired transducers. If an Avalon CL or Avalon CTS base station is connected to the fetal monitor, and both wired and CL transducers are connected to the monitor, all the wired transducers are disabled whenever one CL transducer is active. To switch back to using wired transducers, switch the base station to Standby mode, or redock all CL transducers at the base station, and continue monitoring with the wired transducers. CL NBP and CL SpO2 versus fetal monitor built-in NBP and SpO2 measurements CL NBP and CL SpO2 have priority over the built-in NBP and SpO2 measurements. If a CL NBP or CL SpO2 Pod is activated, the corresponding built-in measurement of the fetal monitor is deactivated. To switch back to the built-in measurements, switch the base station to Standby mode, or redock the CL Pods at the base station. CL F&M Pod versus wired transducers The CL F&M Pod has priority over wired transducers. If a CL F&M Pod is active, all the wired transducers are disabled. To switch back to using wired transducers, switch the base station to Standby mode, or redock the CL F&M Pod at the base station. About RF Signal Quality If you cannot get sufficient ultrasound signal quality using the Avalon CTS base station, try repositioning the transducers, or switch to wired transducers. Using an Avalon CL base station you should get a better signal by reducing the distance between the CL transducer and the base station. Signal transmission can be disturbed if:
the patient is out of range of the receiving area. there is interference from another, possibly stronger, RF signal (a broadcasting station, for instance). the patient is near material that absorbs electromagnetic waves (for example, metal-reinforced concrete, elevator doors) or the base station is in an enclosed metal rack. 97 4 Cableless Monitoring CL Transducer Assignment The CL transducers are assigned by simply docking them at the Avalon CL base station connected to the patients fetal monitor. Since twins and triplets can be monitored with the Avalon CL base station, it can be delivered with up to six CL transducers: one CL Toco+ MP, three CL US, and two CL ECG/IUP transducers. Up to four CL transducer can be assigned at one time to the Avalon CL base station. Four assigned CL transducers enable monitoring combinations such as 1 CL Toco+ MP transducer + 3 CL US transducers for monitoring triplets externally, or 1 CL Toco+ MP transducer + 2 CL US transducer +
1 CL ECG/IUP transducer for monitoring twins. Three CL transducers can be docked and charged at the Avalon CL base station at a time. If a fourth transducer should be assigned to the Avalon CL base station:
1 Remove first the three docked CL transducers from the base station and place them on the patient. 2 Then dock the remaining fourth transducer at the base station and wait until the LED of the fourth transducer signals that it has communication with the base station. Place the fourth CL transducer on the patient and check on the fetal monitor in the Tele Info window if the base station and the monitor have communication with all four transducers, and if their numerics are displayed on the screen of the fetal monitor. 3 CL Transducer Unassignment The cableless transducer needs to be unassigned:
before being used with another base station on another patient to allow cleaning before docking it back onto the base station (e.g. to replace it with a fully charged transducer of the same type) Select Remove from the open setup menu. There are three methods to do this:
1 Open the setup menu of the measurement e.g. FHR1 by selecting the numeric on the screen. 2 3 A confirmation window opens with the prompt Please Confirm and Device will be removed. 4 or 1 Open the Tele Info window. 2 Select the Confirm pop-up key. A message confirms cl US has been removed. Select the symbol of the cableless transducer you want to unassign, and select Remove from the pop-up menu. Select Confirm the pop-up key. A message confirms cl US has been removed. 3 A confirmation window opens with the prompt Please Confirm and Device will be removed. 4 or 1 Redock the CL transducer at the base station. 2 3 Remove the CL transducer; it is now unassigned. Switch the base station to stand-by. 98 4 Cableless Monitoring NOTE When a CL transducer is unassigned, all the measurements from this transducer are no longer monitored; e.g. if you unassign a CL Toco+MP transducer, the Toco measurement, maternal Pulse, or possibly also MECG or DECG are no longer monitored. CL Pod Assignment Select Remove from the open setup menu. before assigning them to another base station or to another patient to allow cleaning, before docking them back onto the base station The CL Pods are assigned by simply docking them at the Avalon CL base station connected to the patients fetal monitor.

Select the Confirm pop-up key. A message confirms <cl Measurement> has been removed. Select the Confirm pop-up key. A message confirms <cl Measurement> has been removed. Select the symbol of the CL Pod, and select Remove from the pop-up menu. Switch the base station to stand-by. To unassign a IntelliVue CL Pod using its user interface, see the Cableless Measurement Instructions for Use. NOTE If you unassign a CL Pod, all the measurements from it are no longer monitored, or are monitored by a connected lesser prioritized sensor. 99 4 Cableless Monitoring Preparing to Monitor Cablelessly When monitoring cablelessly with the FM20/30/40/40 monitors, most of the same procedures apply as described in Preparing to Monitor on page 48. Additions and deviations applying to cableless devices and existing procedures are described here. CL Transducers 1 2 To monitor cablelessly with the CL transducers, assign them at the base station as described in CL Transducer Assignment on page 98. Place the CL transducers and the belt on the patient described in Fastening Belts and Transducers on page 50. 3 Check the measurements on the monitor, and if necessary, move the CL transducers until you have a good signal for all measurements. IntelliVue CL Pods 1 2 To monitor cablelessly with the IntelliVue CL Pods, assign them at the base station as described in CL Pod Assignment on page 99. Put the CL Pods in their cradles and place them on the patient as described in the IntelliVue Cableless Measurements Instructions for Use. Applying the CL Fetal & Maternal Patch and Pod WARNING Do not use the CL Fetal & Maternal Pod and electrode patch for monitoring if:
The skin on the abdomen of the patient has established erythema, lesions, infection, inflammation, or any kind of injuries at the applications site The patient has a history of skin irritation, allergies, or hypersensitivity to adhesives The patient carries multiple fetuses The gestational age is less than 36 completed weeks. The measurement method is also only validated with patients in labor. CAUTION During handling, avoid close contact of the CL Fetal & Maternal Pod or the electrode patch to an implanted pacemaker or defibrillator. 100 4 Cableless Monitoring At the Mother's Side 1 Have a new single-use electrode patch ready, and make sure that the pouch is still intact. Check the expiration date that is printed on the pouch. 2 Clean the application area on the abdomen of the patient. Use mild soap to wash any cream, oil, or gel from the abdomen. Make sure to thoroughly wipe the area dry afterwards, ideally using paper towels. 3 Take the electrode patch from its pouch. 4 Study the electrode patch Instructions for Use showing the correct placement of the electrode patch on the abdomen of the patient. 5 Remove the cover from the adhesive area under the central area of the patch. (Do not remove the cover from any of the five surrounding electrodes yet). 6 Verify the correct orientation of the patch. The Philips/Monica printed top electrode must point 7 8 to the patients chest. Place the central adhesive area of the patch over the patients umbilicus as shown in the patch Instructions for Use. Then press it down. For patients with a displaced umbilicus:
Where the umbilicus has been displaced downwards, position the center of the patch along the midline, where it intersects the horizontal line passing over the iliac crests. Alternatively, estimate the mid-point between the fundus and symphysis pubis. For very obese patients or patients with a large panniculus:
An alternative strategy is to position the patch along the midline such that the edge of the top electrode is placed 10-12 cm (4-5 in) below the fundus. Lift up one of the four electrodes. Identify the small area of the skin where you will place the center of the electrode. 9 Use one piece of abrasive ECG skin preparation paper to prepare the patient's skin. Make three horizontal and three vertical strokes with the skin preparation paper. Focus the strokes on the small area of the skin where the conductive center of the electrode will be placed. Make deliberate but gentle strokes, lifting the finger after each stroke. CAUTION Do not use too much pressure with the abrasive skin preparation paper to avoid skin injury. incorrect correct 10 Remove the protective cover from the electrode. Place the electrode on the prepared skin. Press it down firmly, but avoid pressing the central gel area of electrode. 11 Repeat the steps for the skin preparation and electrode placement for the other three electrodes. 101 4 Cableless Monitoring 12 For the last remaining electrode attached to the long flexible cable, identify the small area of skin to prepare, so that the center of this reference electrode will be positioned on the midline, approximately 6 cm (2.4 in) above the rim of the symphysis pubis. For patients with a displaced umbilicus, very obese patients, or patients with a large panniculus:
Place the electrode on top of the panniculus approximating to the point 6 cm (2.4 in) vertically from the symphysis pubis. If during monitoring the aFHR signal quality is poor, reposition the electrode lower down on the abdomen to maximize the FHR signal, and consider placing the electrode under the panniculus just below the turn. 13 Prepare the skin like for the first four electrodes. 14 Remove the protective cover from the electrode. Then place the electrode on the prepared skin and press it down firmly, but avoid pressing the central gel area of electrode. 15 Assign a CL F&M Pod at the base station as described in CL Pod Assignment on page 99. 16 Place the CL F&M Pod on the electrode patch. 1 CL F&M Pod and electrode patch centered on the umbilicus Placement of electrode 6 cm (2.4 in) above the rim of the symphysis pubis 2 102 4 Cableless Monitoring At the Monitor After you have placed the CL F&M Pod on the electrode patch, the cl F&M Electrode Status window opens at the monitor. In the cl F&M Electrode Status window, the electrodes and their skin contact status are shown. The skin contact status indicates, whether the skin preparation at each electrode site was successful. 1 There are three methods to reopen a closed cl F&M Electrode Status window. Select:
The clF&M Status SmartKey (configurable) cl F&M Status in the setup menu of one of the CL F&M parameters (for example, Setup aFHR1) cl F&M Status from the Main Setup menu Electrode Status Description What to Do The skin contact status is good. Further skin preparation may be required. When a good skin contact status is indicated for all five electrodes, the cl F&M Electrode Status window closes, and the measurement starts automatically. 1 Carefully remove the electrode from the skin. 2 Dry the skin. 3 Repeat the skin preparation procedure. 4 If the contact status cannot be improved, you can choose to skip the electrode status check by selecting the Skip Check, Start Measurement button in the cl F&M Electrode Status window. Measurement accuracy should not be affected, but fetal heart rate detection may be less sensitive. 103 4 Cableless Monitoring Electrode Status Description Further skin preparation is required. Electrode status is unknown. What to Do 1 Carefully remove the electrode from the skin. 2 Dry the skin. 3 Repeat the skin preparation procedure. 4 It is not recommended to skip the electrode status check, if bad skin contact quality is persistently indicated for one or more electrodes. This status may be shown temporarily, or in case of a patch malfunction, combined with an INOP message. NOTE If you have to repeat the skin preparation, or fix a loose electrode, ensure that enough wet gel remains in the conductive middle of the electrode during the reapplication of the electrode. Add additional fixation (any type of medical grade tape) to the pad in case the adhesive is compromised. If you cannot get a good measurement signal quality, use an alternative monitoring method. The electrode patch can remain applied for up to 48 hours. Remove the electrode patch, if there are signs of skin irritation. If you have to replace an electrode patch:
Gently remove the electrode patch from the abdomen of the patient. Wipe the abdomen dry thoroughly. Apply a new patch over exactly the same location. In this case, no further skin preparation is required. Monitoring with the CL F&M Pod and electrode patch can continue when the patient takes a shower. However, ensure that the CL F&M Pod remains on the electrode patch all the time, to keep the contacts of the electrode patch dry. The achievable maximum wireless operating range may be compromised when monitoring under a shower. The CL Fetal & Maternal Pod is not intended for underwater monitoring, for example in a bathtub. CAUTION Do not reuse a patch on another patient due to the risk of cross contamination. 104 4 Cableless Monitoring After Monitoring 1 After monitoring is done, remove the CL F&M Pod from the electrode patch. 2 Clean and disinfect the CL F&M Pod, see Care and Cleaning on page 261. 3 Dock the CL F&M Pod back at the base station. 4 Gently remove the electrode patch and the electrodes from the abdomen of the patient. 5 Dispose of the electrode patch. 6 Remove the residuals of the adhesive from the patient's skin. CL Wide Range Pod The CL Wide Range Pod extends the signal range for the cableless measurement devices worn by the ambulating patient. 1 Assign the CL Wide Range Pod at the base station as described in CL Pod Assignment on page 99. 2 Activate the CL Wide Range Pod by taking it off the base station. The CL Wide Range Pod connects itself over WLAN and LAN with the fetal monitor. As soon as the connection to the monitor is established, the CL Wide Range Pod takes over from the base station, and sends the signals from the cableless devices to the monitor. The connection status of the CL Wide Range Pod is shown on the monitor, see Cableless Status Indication on page 95. 3 Hand the CL Wide Range Pod to the patient to carry with her, or optionally wearing it using the Mobile CL Transmitter Cradle (989803168881). The CL Wide Range Pod should be worn with its rear side facing the body. CL Wide Range Pod carried in hand, or CL Wide Range Pod worn with the belt clip (supporting loop and belt clip part of the optional Mobile CL Transmitter Cradle). 4 While the CL Wide Range Pod is active, cableless devices can still be assigned or unassigned at the base station dynamically to the patient. To hand the signal transfer back from the CL Wide Range Pod to the base station, redock the CL Wide Range Pod at the base station. 105 4 Cableless Monitoring Battery Lifetime Management The lifetime of a Lithium Ion battery depends on the frequency and duration of use. CL Transducers Battery replacement is recommended after 500 charge-discharge cycles, or if the battery is older than 4 years whatever is reached first. If the battery of a cableless transducer has aged and an exchange of the battery is highly recommended, a prompt message is displayed at the fetal monitor for ca. 60 seconds. The prompt is repeated whenever the Tele Info window is opened until the battery is replaced. The CL transducer battery allows for 10 hours of continuous operation. Depending on the transducer type the following messages are displayed:
cl US battery has aged. Replacement strongly recommended cl Toco battery has aged. Replacement strongly recommended cl ECG/IUP batt has aged. Replacement strongly recommended If you are getting this message, contact your service personnel so they can replace the CL transducer's battery. CL F&M Pod Pod replacement is recommended after 500 charge-discharge cycles, or if the battery is older than 4 years whatever is reached first. If the battery of a CL F&M Pod has aged and an exchange of the Pod is highly recommended, a prompt message is displayed at the fetal monitor for ca. 60 seconds. The prompt is repeated whenever the Tele Info window is opened. The CL F&M battery allows for 16 hours of continuous operation. The following message is displayed:
cl F&M battery has aged. Replacement strongly recommended If you are getting this message, contact your service personnel so they can replace the CL F&M Pod. CL Wide Range Pod Battery replacement is recommended after 500 charge-discharge cycles, or if the battery is older than 4 years whatever is reached first. If the battery of a CL Wide Range Pod has aged and an exchange of the battery is highly recommended, a prompt message is displayed at the fetal monitor for ca. 60 seconds. The prompt is repeated whenever the Tele Info window is opened until the battery is replaced. The CL Wide Range Pod battery allows for 4 hours of continuous operation The following message is displayed:
cl WRP battery has aged. Replacement strongly recommended CL NBP and CL SpO2 Pods For battery charge-discharge cycles specification of the IntelliVue CL Pods (NBP and SpO2), refer to the Service Guide of the Cableless Measurements. Charge Cycle The age of a lithium ion battery begins at the date of manufacture. The lithium batteries are designed for frequent recharging. A complete charging cycle is only reached and counted, when all recharging periods equal a 100% charge. 106 4 Cableless Monitoring The date of manufacture and number of charge-discharge cycles can be printed out in a battery report. Patient Transport Within the Hospital During transport, the patient wearing the CL transducers can be transferred from one fetal monitor to another fetal monitor. 1 To stop monitoring, discharge the patient at the fetal monitor. Do not switch the CL base station to Standby. Note: If you switch the CL base station to Standby after the discharge, the CL transducers only hold the assignment to the CL base station for 1 minute. 2 Disconnect the CL base station from the fetal monitor. 3 The CL transducers hold the assignment to the CL base station for 30 minutes. Transport the patient wearing the CL transducers with the disconnected CL base station to another fetal monitor. 4 Connect the CL base station to the other fetal monitor. The fetal monitors need to have the same software revisions, and the correct time and date settings. 5 Manually admit the patient to the fetal monitor, unless the patient is transferred to the new fetal monitor with the OB TraceVue/IntelliSpace Perinatal system. 6 Resume monitoring. Once the base station and the transducer are connected and assigned to the new monitor, the previous monitor can be switched off or to Standby. 107 4 Cableless Monitoring Underwater Monitoring Only the battery-operated CL transducers of the Avalon CL and Avalon CTS systems can be used to monitor under water. You can use them to monitor patients in a bathtub or shower. This does not apply to the IntelliVue CL SpO2, CL NBP, and the CL Wide Range Pod, do not immerse the CL Pods into water. The CL F&M Pod can be worn within the shower, if the Pod is securely placed on the electrode patch, so that the contacts cannot get wet. Radio transmission range of the CL F&M Pod may be reduced under a shower. Cableless transmission distances are shorter when monitoring under water. A metal bathtub is likely to further reduce the operating range. WARNING Never immerse the base station in liquid. You must protect it against water sprays or splashes. Place the base station where there is no chance of contact with water, or falling into water or other liquids. CAUTION Avoid the use of pulsating water jets in the bath or shower while monitoring, as these can be misinterpreted as an incorrect (or totally artificial) heart rate. Toco Baseline drift: When using transducers under warm water, the temperature increase causes a significant baseline change due to internal pressure increase. The depth under water at which the Toco transducer is used also has an effect on the Toco baseline, as the water pressure increases with depth. After immersion, allow one to two minutes for the pressure to stabilize, then adjust the Toco baseline
(between contractions), and check it frequently. When using the transducers underwater, the radio transmission range is reduced, and signal loss may occur. Water-proof belts like M1562B are recommended for the cableless transducers when monitoring in water. 108 5 5FM20/30 Battery Option You can switch between battery-powered and mains-powered (AC) operation without interrupting monitoring. The monitor is connected to the AC mains power via the external power supply. NOTE The battery option is not available for the FM40/FM50. External Power Supply M8023A The external power supply M8023A (option #E25) allows you to operate the fetal monitor from an AC (alternating current) power source of 100 V to 240 V (10%) and 50/60 Hz (5%). If this option is used, then the M8023A (option #E25) power supply is included for FM20/30. 109 5 FM20/30 Battery Option 1 AC power cord, connected to AC mains socket 2 Measurement Link (MSL) cable, supplies the power to the monitor for operation and for battery 3 charging Power-on LED, the green light is on when the external power supply is connected to the AC mains WARNING Always use the supplied power cord with the earthed mains plug to connect the external power supply M8023A (option #E25) to an earthed AC mains socket. Never adapt the mains plug from the power supply to fit an unearthed AC mains socket. Do not use AC mains extension cords or multiple portable socket-outlets. If a multiple portable socket-outlet without an approved isolation transformer is used, the interruption of its protective earthing may result in enclosure leakage currents equal to the sum of the individual earth leakage currents, so exceeding allowable limits. Do not connect any devices that are not supported as part of a system. Any non-medical device placed and operated in the patients vicinity must be powered with an approved isolation transformer that ensures mechanical fixing of the power cords and covering of any unused power outlets. Using Batteries The Lithium Ion batteries used in your monitor store a large amount of energy in a small package. This allows reliable battery-operated monitoring, but also requires care in use and handling of the batteries. Follow the instructions in this chapter and see the Service Guide for further details. Battery Power Indicators The battery LED and battery status information on the main screen, in combination with INOP messages and prompts, help you keep track of the battery power status. The indicators always show the remaining capacity in relation to the battery's actual maximum capacity, which may lessen as the battery ages. You can see the actual capacity in the Battery Status window. 110 Battery LED The possible battery LED status on the right side of the monitor is described in the table below. 5 FM20/30 Battery Option Battery LED Colors Green Yellow Red, flashing If the monitor is connected to mains power, this means Battery power is >90%
Battery charging (battery power
< 90%) Red, flashes intermittently Battery or charger malfunction If the monitor is running on battery power, this means Less than 10 minutes power remaining Battery malfunction Battery Status on the Main Screen Battery status information is permanently displayed on all screens. It shows the status of the battery, with the battery power remaining, with an estimate of the monitoring time this represents. Battery power gauge: This shows the remaining battery power. It is divided into sections, each representing 20% of the total power. If three sections are filled, as in this example, this indicates that 60% battery power remains. If no data is available from the battery, a question mark is shown in the gauge. Monitoring Time Available: Below the battery power gauge a time is displayed. This is the estimated monitoring time available with the current battery power. Note that this time fluctuates depending on the system load (the display brightness, the recorder configuration, and how many measurements you carry out). 111 5 FM20/30 Battery Option Battery malfunction symbols: Normal battery function is indicated by the battery power gauge, together with the remaining operating time, on the main screen. You are informed of problems or changes in the status of the battery by the battery status/malfunction indicator. This consists of a blank battery gauge containing a "!" symbol. If the symbol is red, this indicates a critical situation. You can check the specific cause of the problem by looking at the symbol(s) displayed in the Battery Status window. Battery Status Indicator Battery Malfunction Indicator Alternates with the battery gauge on the main screen. Check in the Battery Status window to see which status symbol is displayed to identify the cause. The red exclamation mark flashes. Critical battery situation or malfunction. Check in the Battery Status window to see which malfunction indicator is displayed, or refer to the INOP, to identify the cause. Battery Status Window 1 To access the Battery Status window and its associated pop-up keys, select the battery status information on the screen, or select Main Setup, Battery. Capacity, remaining tells you how much power is left in the battery. Capacity, fullCharge tells you how much power the battery can hold when fully charged. TimeToEmpty tells you approximately how long you can continue to use the monitor without an AC connection. The time span fluctuates depending on the system load (the display brightness and how many measurements you carry out), and the remaining capacity of the battery. TimeToFull is shown in place of TimeToEmpty if the monitor is connected to a power supply, and tells you how much time is left until the battery is charged to 90%. If >10 hr is shown here, the battery may not charge completely when the monitor is in use. Battery status/malfunction symbols: If a problem is detected with the battery, an INOP may be issued, and the following symbols are displayed in the Battery Status window, where they may be accompanied by a status message providing more details. 112 5 FM20/30 Battery Option Symbols indicating critical situations are colored red. Battery Status Symbols Battery Malfunction Symbols Battery is empty
(Red) incompatible battery Battery not charging as the temperature is above or below the specified range Battery requires maintenance Charging stopped to protect the battery
(Red) battery malfunction
(Red) battery has no power left
(Red) battery temperature too high
(Red) battery is missing, insert battery Checking Battery Charge To check the charge status of a battery, refer to the battery power gauge on the screen, or open the Battery Status window. When Battery Lifetime is Expired When the battery is aged, either after 3 years from manufacturing date or after 500 charge-discharge cycles, it is recommended to replace the battery. To remind you of this, a message will appear in the Battery Status window. This message will only be displayed at the appropriate time when the date and time on the monitor is correct. Optimizing Battery Performance The performance of rechargeable batteries may deteriorate over time. Battery maintenance as recommended here can help to slow down this process. Display Brightness Setting 1 In the Main Setup menu, select User Interface, Brightness, then Optimum. This selects a level of brightness suitable for most monitoring locations that uses less battery power than brighter settings. 2 Ensure that the current level of brightness is suitable for your monitoring location. 113 5 FM20/30 Battery Option Charging the Battery To charge the battery:
1 Connect the monitor to the external power supply (M8023A). 2 Charge the battery until it is full, the battery LED is green, and the battery power gauge is filled. During high load of the monitor (usage of multiple measurements) the battery may not charge. To remedy this:
Internal temperature conditions can also cause the battery to not charge. This is necessary to protect the battery from damage and does not indicate a malfunction. Keep the monitor at room temperature and move it away from heat sources or out of direct sunlight. The battery will resume charging when the temperature is within range again. The battery will charge more quickly if the monitor is switched off. reduce the load by removing measurements reduce the screen brightness or stop the recorder Conditioning the Battery You must condition the battery when the "battery requires maintenance" symbol shows on the screen. Do not interrupt the charge or discharge cycle during conditioning. CAUTION Condition the battery with a monitor not currently in use. The monitor switches off automatically when there is no battery power left. To condition the battery:
1 Charge the battery until it is completely full. Open the Battery Status window and check that the Batt fully charged message is displayed. 2 Disconnect the monitor from mains power, and let the monitor run until there is no battery power left and the monitor switches itself off. 3 Reconnect the monitor to mains power and charge the battery until it is full for use or charge to 50% for storage. 114 Battery Safety Information 5 FM20/30 Battery Option WARNING Use only Philips batteries part number M4605A. Use of a different battery may present a risk of fire or explosion. Do not open batteries, or dispose of them in fire, or cause them to short circuit. They may ignite, explode, leak, or heat up, causing personal injury. If battery leakage should occur, avoid contact with skin. Refer to qualified and authorized service personnel. Dispose of used batteries promptly and in an environmentally responsible manner. Do not dispose of the battery in normal waste containers. Consult your hospital administrator to find out about local arrangements. Do not expose batteries to liquids. Do not crush, drop, or puncture batteries - mechanical abuse can lead to internal damage and internal short circuits which may not be visible externally. If a battery has been dropped or banged against a hard surface, whether damage is visible externally or not:
Keep batteries out of the reach of children. discontinue use dispose of the battery in accordance with the disposal instructions above. CAUTION Do not disassemble, heat above 100C (212F) or incinerate the batteries, to avoid the risk of fire and burns. Keep batteries out of the reach of children and in their original package until you are ready to use them. If battery leakage should occur, use caution in removing the battery. Avoid contact with skin. Refer to qualified and authorized service personnel. Do not install or use pre-damaged batteries. Storing the Battery WARNING Remove the battery from the monitor when it is not used for a longer period of time, to avoid potential damage caused by battery leakage. Batteries should be charged to a maximum of 50% for storage. The battery will discharge over time if it is stored inside the monitor without AC power connection. The reported values for "remaining capacity" and "runtime" will become less accurate when the battery is stored in this way for a longer period of time (that is, several weeks). 115 5 FM20/30 Battery Option Cableless Monitoring with FM20/30 Battery Option The CL Pods can be used with the FM20/30 with battery option #E25. The CL Pods can be assigned and activated, but will not be charged. The only exception to this is the CL F&M Pod, which can also be charged. The charging time of the CL transducers can take up to 6 hours if they are charged from an FM20/30 with battery option. If you charge the CL transducers at an FM20/30 with battery option, be sure to remove all wired transducers from the fetal monitor. Leaving them connected to the fetal monitor can cause the CL transducers not to charge at all. Patient Transport Within the Hospital The FM20 and FM30 fetal monitor with battery option offer the possibility of continuous monitoring of a patient, while she is transported within the hospital. 1 Unplug the MSL connector at the fetal monitor. Or, in case an external power supply is mounted on a rollstand, unplug it from the AC Mains. The fetal monitor is now operating on battery power. 2 Move the patient with the fetal monitor (on a cart) to the new location. 3 Reconnect the MSL connector at the fetal monitor or the external power supply to the AC Mains. 116 6Alarms 6 The alarm information here applies to all measurements. Measurement-specific alarm information is contained in the sections on individual measurements. The fetal monitor has two different types of alarm: patient alarms and INOPs. Patient Alarms Patient alarms are red and yellow alarms. A red alarm indicates high priority, such as a potentially life threatening situation (for example, SpO2 below the desaturation alarm limit). A yellow alarm indicates a lower priority alarm (for example, a fetal heart rate alarm limit violation). INOPs INOPs are technical alarms. They indicate that the monitor cannot measure and therefore not detect critical conditions reliably. If an INOP interrupts monitoring and alarm detection (for example, MECG Leads Off), the monitor places a question mark in place of the measurement numeric and sounds an audible tone. INOPs without this tone indicate that there may be a problem with the reliability of the data, but that monitoring is not interrupted. INOPs are cyan by default. The following INOPs can also be configured as red or yellow INOPs to provide a severity indication:
Alarm Delays There is a delay between a physiological event at the measurement site and the corresponding alarm indication at the monitor. This delay has two components:
The general measurement delay time is the time between the occurrence of the ECG Leads Off Battery Empty (FM20/30, CL devices) Cuff Overpress Cuff NotDeflated No Pulse physiological event and when this event is represented by the displayed numerical values. This delay depends on the algorithmic processing and on the measurement dependent averaging time. 117 6 Alarms The time between the displayed numerical values exceeding an alarm limit and the alarm indication on the monitor. This delay is the sum of the alarm delay configured for the specific measurement plus the system alarm delay. The system alarm delay is the processing time the system needs for any alarm on the monitor to be indicated after the measurement has triggered the alarm. See the performance specifications in Specifications and Standards Compliance on page 287 for the system alarm delay specification. Multiple Alarms If more than one alarm is active, the alarm messages are shown in the alarm status area in succession. An arrow symbol next to the alarm message informs you that more than one message is active. The monitor sounds an audible indicator for the highest priority alarm. If more than one alarm condition is active in the same measurement, the monitor announces the most severe alarm condition first. WARNING Alarm systems of the monitor and those of the connected obstetrical information and surveillance system are independent and not synchronized. Alarming is only available at the Avalon fetal monitor, not at the Cableless Measurement Devices, see the Instructions for Use for the IntelliVue Cableless Measurements. If configured so, SpO No Pulse will only be displayed in yellow or red (instead of cyan), when no other Pulse source is valid and is displayed instead of the Pulse from SpO2. Alarm Mode You can configure the alarm mode for your fetal monitor. There are two possible modes:
All: alarms and INOPs are enabled, with all audible and visual indicators active. INOP only: only INOPs are enabled, with audible and visual indication active. WARNING In INOP only mode, no fetal/maternal patient alarms are enabled or indicated. The alarm status area for yellow and red alarms shows the INOP only indication in conjunction with the
"Alarms Off" symbol. No individual measurement alarm limits or alarm off symbols are displayed. No fetal/maternal patient alarm settings are available in the setup menus. Nurse Call Systems If configured to do so, red, yellow, and cyan alarms are indicated on a nurse call system which is connected to the optional nurse call relay. 118 Visual Alarm Indicators 6 Alarms Alarm message: An alarm message appears in the alarm status area on the second line at the top of the screen indicating the source of the alarm. If more than one measurement is in an alarm condition, the message changes every two seconds, and has an arrow at the side. The background color of the alarm message matches the alarm priority: red for red alarms and red INOPs, yellow for yellow alarms and yellow INOPs, and cyan for INOPs. The asterisk symbols (*) beside the alarm message match the alarm priority: *** for red alarms, and ** for yellow alarms. INOPs are displayed without asterisks, but a red INOP has !!! three exclamation marks, and a yellow INOP has !! two exclamation marks before it. Depending on how your monitor is configured, it may display alarm limit violation messages:
in text form, for example ** FHR1 Low or in numeric form, for example **FHR1 94<110, where the second number shows the currently set alarm limit, and the first number shows the value at which that alarm limit was violated by the widest margin. Flashing numeric: The numeric of the measurement in alarm flashes. Bright alarm limits: If the alarm was triggered by an alarm limit violation, the corresponding alarm limit on the monitor screen is shown more brightly. Audible Alarm Indicators The audible alarm indicators configured for your fetal monitor depend on which alarm standard applies in your hospital. Audible alarm indicator patterns are repeated until you acknowledge the alarm by switching it off or pausing it, or until the alarm condition ceases (if audible alarm indication is set to non-latching). WARNING Do not rely exclusively on the audible alarm system for fetal monitoring. Adjustment of alarm volume to a low level or off during monitoring may result in a dangerous situation. Remember that the most reliable method of fetal monitoring combines close personal surveillance with correct operation of monitoring equipment. Alarm Tone Configuration The audible alarm indicators of your monitor are configurable. In the monitor's Configuration Mode, you can:
increase the alarm volume of unacknowledged alarms at regular intervals change the interval between alarm sounds (ISO/IEC Standard alarms only) change the base volume of the red and yellow alarm tones and the INOP tones change the alarm sound to suit the different alarm standards valid in different countries 119 6 Alarms Standard Philips Alarms Red alarms and red INOPs: a high pitched sound is repeated once a second. Two-star yellow alarms and yellow INOPs: a lower pitched sound is repeated every two seconds. One-star yellow alarms (short yellow alarms): the audible indicator is the same as for yellow alarms, but of shorter duration. Standard INOPs: an INOP tone is repeated every two seconds. ISO/IEC Standard Audible Alarms Red alarms and red INOPs: a high pitched tone is repeated five times, followed by a configurable pause. Two-star yellow alarms and yellow INOPs: a lower pitched tone is repeated three times, followed by a configurable pause. One-star yellow alarms (short yellow alarms): the audible indicator is the same as for yellow alarms, but of shorter duration. Standard INOPs: a lower pitched tone is repeated twice, followed by a pause. Changing the Alarm Tone Volume The alarm volume symbol at the top right of the monitor screen gives you an indication of the current volume. To change the volume:
1 Select the volume symbol. 2 The volume scale pops up. 1 Alarm Volume 3 Select the required volume from the volume scale. When the alarm volume is set to zero (Off), the alarm volume symbol shows this symbol:
If you switch the alarm volume off, you will not get any audible indication of alarm conditions. 120 Minimum Volume for Severe Yellow or Red INOPs 6 Alarms Severe yellow or red INOPs require action to ensure the well-being of the patient. Therefore the minimum volume for the INOP tone is set to at least alarm volume 8, irrespective of the current alarm volume setting. The INOP tone will sound even if the monitor alarm volume is set to zero. The severe INOPs for which this applies are:
INOP Battery Empty Factory Default cyan INOP tone severe (fetal monitor with battery option) severe (CL transducers and Pods) severe severe Battery Empty Cuff Overpress Cuff NotDeflated cyan cyan cyan Power Loss Tone FM20/30 with Battery Option, FM40/50 When power is lost - no power is available from the AC power source or from the battery - a beeper will sound. The tone can be silenced by pressing the On/Standby button. Acknowledging Alarms To acknowledge all active alarms and INOPs, select the Silence key. This switches off the audible alarm indicators. A checkmark beside the alarm message indicates that the alarm has been acknowledged. If the condition that triggered the alarm is still present after the alarm has been acknowledged, the alarm message stays on the screen with a checkmark symbol beside it. If the alarm condition is no longer present, all alarm indicators stop and the alarm is reset. Switching off the alarms for the measurement in alarm, or switching off the measurement itself, also stops alarm indication. Acknowledging Disconnect INOPs Acknowledging an INOP that results from a disconnected transducer, switches off the associated measurement. 121 6 Alarms Alarm Reminder If Alarm Reminder is configured on for your monitor, you will get an audible reminder of alarm conditions that remain active after you have acknowledged the alarm. This reminder may take the form of a repetition of the alarm tone for a limited time, or an unlimited repetition of the alarm tone (this is the same as a new alarm). Alarm Reminder is available only for yellow and red alarms and INOPs and not for standard cyan INOPs. In Configuration Mode, you can set the interval between silencing the alarm and sounding the reminder tone to one, two, or three minutes. Pausing or Switching Off Alarms Select Main Setup, Alarms, Alarm Settings. If you want to temporarily prevent alarms from sounding, for example while you are moving a patient, you can pause alarms. Depending on your fetal monitor configuration, alarms are paused for one, two, or three minutes, or infinitely. To view the alarm pause setting chosen for your unit:
1 2 Check the Alarms Off setting. This setting can be changed in Configuration Mode. There are some settings made in Configuration Mode that can affect the availability of the pause alarms functionality. The Pause Alarms/Alarms Off SmartKey can be removed from the screen to avoid unintentional switching off of alarms. In this case you can only pause alarms or switch alarms off permanently in the Alarms menu, under Main Setup. The Pause Alarms/Alarms Off SmartKey can be configured to pause or switch off red and yellow alarms, yellow alarms only, or not to function at all. If it is configured not to function, you cannot pause alarms or switch alarms off permanently at all. When the alarms off priority is set to Yellow Only, the Pause Alarms/Alarms Off key becomes the Pause Yellow/Yellow Al. Off. To Pause All Alarms If you have configured alarms to be paused for one, two, or three minutes, the SmartKey is labeled Pause Alarms. Select the Pause Alarms SmartKey to pause all alarms. Or 1 2 3 Select Main Setup. Select Alarms. Select Pause Alarms. 122 To Switch All Alarms Off You can switch alarms off permanently if your monitor is configured to allow infinite alarms pause, and the SmartKey is labeled Alarms Off. Select the Alarms Off SmartKey. 6 Alarms Or 1 2 3 Select Main Setup. Select Alarms. Select Alarms Off. While Alarms are Paused or Off When red alarms are paused or off:
In the alarm field, the monitor displays the message Al. Paused x:yy or Alarms Off, together with the alarms paused symbol or the alarms off symbol. When yellow alarms are paused or off:
In the alarm field, the monitor displays the message YellowPaused x:yy or Yellow Alarms Off, together with the alarms paused symbol or the alarms off symbol. For red and yellow alarms:
Alarms Paused Alarms Off INOP messages are shown but no INOP tones are sounded. No alarms are sounded and no alarm messages are shown. The only exceptions are the INOPs Cuff NotDeflated, Cuff Overpress, and Battery Empty from the FM20/30 monitor with battery option. These INOPs switch all alarms back on again, so that an INOP tone can be sounded. You must remove the INOP condition first, before you can switch off or pause the alarms again. Restarting Paused Alarms To manually switch on alarm indication again after a pause, select the SmartKey Pause Alarms (or Alarms Off) again. Alarm indication starts again automatically after the pause period expires. If the monitor is configured to stay paused infinitely, you must select Alarms Off again to restart alarm indication. 123 6 Alarms Extending the Alarm Pause Time If your monitor has the function extended alarm pause enabled, you can extend the alarm pause time. Use this to prevent alarms being indicated, for example, while you are washing a patient or carrying out a procedure. Only extend the alarm pause time when you are sure that clinical personnel are available to monitor the patient's condition closely. To extend the alarm pause time to five or 10 minutes:
1 2 Select one of the alarm fields. This calls up the Alarm Messages window. Select either the pop-up key PauseAl. 5 min or the pop-up key PauseAl. 10 min. Each time you select one of these pop-up keys, the Alarm Pause Time is reset to five or 10 minutes. To Switch Individual Measurement Alarms On or Off This applies to alarm mode All. Select the measurement numeric to enter its setup menu. Select Alarms to switch between On and Off. 1 2 The alarms off symbol is shown beside the measurement numeric. Alarm Limits The alarm limits you set determine the conditions that trigger yellow and red limit alarms. WARNING Be aware that the monitors in your care area may each have different alarm settings, to suit different scenarios. Always check that the alarm settings are appropriate before you start monitoring. Viewing Individual Alarm Limits (Alarm Mode "All" Only) 1 Alarm Limits You can usually see the alarm limits set for each measurement next to the measurement numeric on the main screen. 124 If your monitor is not configured to show the alarm limits next to the numeric, you can see them in the related measurement setup menu. Select the measurement numeric to enter the menu and check the limits. Changing Alarm Limits 6 Alarms To change individual measurement alarm limits using the measurement's setup menu:
1 In the measurement's setup menu, select the alarm limit you want to change. This calls up a list of available values for the alarm limit. Select a value from the list to adjust the alarm limit. 2 CAUTION Set the alarm limits to a meaningful value for the individual patient. Setting the alarm limits to a too high or too low value may render the alarm function useless. Extreme Alarm Limits for Heart Rate and Maternal Pulse The extreme rate alarms, Extreme Tachy and Extreme Brady, generated by the active alarm source, either HR or Pulse, are set in Configuration Mode by adding a set value (the value) to the high and low alarm limits. 1 Extreme Brady Limit 2 Low Limit 3 High Limit 4 Extreme Tachy Limit 5 Extreme Brady 6 Extreme Tachy You need to know which value has been configured for your monitor. Changing the high and low alarm limits automatically changes the extreme alarm limits within the allowed range. To see the extreme rate alarms set for your monitor, in the Setup ECG menu, see the menu items ExtrTachy and ExtrBrady. 125 6 Alarms Reviewing Alarms To review the currently active alarms and INOPs, select any of the alarm status areas on the fetal monitor screen. The Alarm Messages window pops up. All alarms and INOPs are erased from the monitor's alarm history when you discharge a patient, or if you leave the Demonstration Mode. Alarm Messages Window The Alarm Messages window shows all the currently active alarms and INOPs in chronological order, beginning at the top with the most recent. INOPs are shown on the left hand side, and alarms are shown on the right hand side. Any active red alarms are shown first, followed by yellow alarms. Acknowledged alarms or INOPs are shown with the checkmark symbol. The Alarm Messages window pop-up keys appear when the window is opened. Selecting the Review Alarms pop-up key opens the Review Alarms window. Review Alarms Window 1 2 3 4 5 Alarms On SpO No Pulse Alarms Silenced
** FHR1 High
** SpO Low The Review Alarms window contains a list of up to 300 of the most recent alarms and INOPs with date and time information. If configured to do so, each alarm is shown with the alarm limit active when the alarm was triggered and the maximum value measured beyond this limit. The Review Alarms window also shows any changes made to the Alarms On/Off or Alarms Silenced status. Only the main alarms On/Off transitions are logged in the alarm history, and On/Off alarm transitions for individual measurements are not logged. The information in the Review Alarms window is deleted when a patient is discharged. The Review Alarms window pop-up keys appear when the window is opened. Selecting the Active Alarms pop-up key opens the Alarm Messages window. Latching Alarms The alarm latching setting for your monitor defines how the alarm indicators behave when you do not acknowledge them. When alarms are set to non-latching, their indicators end when the alarm condition ends. Switching alarm latching on means that visual and/or audible alarm indications are still displayed or announced by the monitor after the alarm condition ends. The indication lasts until you acknowledge the alarm. 126 Viewing the Alarm Latching Settings 6 Alarms In the monitor's Main Setup menu, select Alarms. Select Alarm Settings, and see the Visual Latching and Audible Latching settings. To see the alarm latching setting for your monitor:
1 2 This setting can be changed in Configuration Mode. You should be aware of the settings chosen for your unit. There are three possible choices each for visual and audible latching: Red & Yellow, Red Only, and Off. The audible latching configuration can never be configured to a higher level than that configured for the visual latching. In other words, the audible latching setting is always the same level, or lower, than the visual latching setting. For example, if visual latching is configured to Red Only, then audible latching can only be set to Red Only or Off. The following table shows the possible combinations for latching settings:
Possible Combinations for Alarm Latching Settings Visual Latching Setting Red & Yellow Red & Yellow Red & Yellow Red Only Red Only Off Audible Latching Setting Red & Yellow Red Only Off Red Only Off Off Alarm Latching Behavior Alarm Condition Acknowledgment Alarm has not been acknowledged Alarm has been acknowledged Presence Alarm condition still present Alarm condition no longer present Alarm condition still present Alarm condition no longer present Red and Yellow Measurement Alarms Non-latching alarms Visual and audible Alarm tone on Alarm message Flashing numerics All audible and visual alarm indicators automatically stop Alarm tone off Audible alarm reminder (if configured) Alarm message Flashing numerics Audible and visual alarm indicators automatically stop latching Alarm tone on Alarm message Flashing numerics Alarm tone on Alarm message Flashing numerics Alarm tone off Audible alarm reminder

(if configured) Alarm message Flashing numerics Audible and visual alarm indicators automatically stop Audible and visual alarm indicators automatically stop All INOPs except the "unplugged" INOPs are non-latching. 127 6 Alarms Testing Alarms Set the alarm limits. When you switch the fetal monitor on, a self test is started. You should hear a single tone. This indicates that the audible alarm indicators are functioning correctly. For further testing of individual measurement alarms, perform the measurement on yourself (for example SpO2 or NBP) or use a simulator. Adjust alarm limits and check that appropriate alarm behavior is observed. To test the functioning of visible and audible alarms, do the following:
1 Enable the alarm (Alarm Mode needs to be set to All, see the Configuration Guide). 2 3 Measure or simulate the parameter that is out of range, or signal loss. 4 Verify that the visible and audible alarms are working. As an example, to test the FHR alarms:
1 Connect the US transducer to a fetal sensor socket. 2 Enable the FHR alarming (see Turning Alarms On or Off on page 197). Set the high alarm limit and delay to 150 bpm and 60 seconds respectively, and the low alarm limit and delay to 110 bpm and 60 seconds respectively (see Changing Alarm Limits on page 197). 1 Generate a fetal heart rate of approximately 180 bpm (3 beats per second) for more than one minute. 2 Verify the functioning of the visible and audible alarms. Alarm Behavior at Power On If the monitor is switched off for longer than one minute and then switched on again, or after a loss of power lasting longer than one minute, the monitor can be configured to restore either the alarm settings from the monitor's User Defaults, or the most recently used alarm settings. When a patient is discharged, the User Defaults of the monitor are always restored independent of the setting. After any of these situations, ensure that the alarm settings are appropriate for your patient. If power is lost for less than one minute, the alarm settings prior to the power loss are restored. If AlarmsOffAtStart is enabled in Configuration Mode alarms will be initially paused or off the next time the monitor is switched on, depending on a set of related configuration settings, see the Configuration Guide. 128 7 7Patient Alarms and INOPs This chapter lists alarms and technical alarms (INOPs) for the fetal monitors irrespective of their priority. Alarm Messages Fetal alarms are identified by either "FHR", "dFHR", or aFHR. All other alarms without these identifiers refer to maternal parameters.

What to do There is a problem with the SpO2 hardware. Contact your service personnel. Check the sensor placement. Try another adapter cable and sensor. If the INOP persists, contact your service personnel. The update period of displayed values is extended due to a noninvasive blood pressure measurement on the same limb, or an excessively noisy signal. Accuracy may be compromised due to very low perfusion. Stimulate circulation at sensor site. If INOP persists, change the measurement site. Check the perfusion at measurement site. If necessary, stimulate circulation or change measurement site. If the INOP is due to noninvasive blood pressure measurement on the same limb, wait until the measurement is finished. Ensure the SpO2 sensor is connected. If the INOP persists, try another adapter cable and sensor. If you silence this INOP, the measurement will be switched off. Excessive patient movement or electrical interference is causing irregular pulse patterns. Try to reduce patient movement, or to relieve the cable strain on the sensor. The signal condition of the SpO2 measurement is poor and measurement accuracy may be compromised. The detectable pulsations of the SpO2 signal are outside the specified pulse rate range. SpO2 is analyzing the patient signal to derive Pulse, and SpO2 values. Please wait until the search analysis is complete. The SpO2 sensor or adapter cable is faulty. Try another adapter cable and sensor. If the INOP persists, contact your service personnel. The SpO2 sensor is not properly applied to the patient. Apply the sensor following the instructions supplied by the manufacturer. The connected sensor or adapter cable is not supported by the SpO2 measurement. Use only specified sensors and cables. 144 7 Patient Alarms and INOPs INOP Message SpO Upgrade SpOInterference Indication Monitor: display only Numeric unavailable Monitor: INOP tone Numeric is replaced by a -?-

146 What to do If this INOP appears and an INOP tone sounds, check the Cableless Measurement Device and patient settings before you resume making measurements. If the settings are unexpected, there may be a problem with the Cableless Measurement Device software. Contact your service personnel. If this INOP is acknowledged at the Cableless Measurement Device, it is cleared. If it is silenced remotely, only the tone is cleared. The CL SpO2 Pod has lost the SRR connection to the monitor. The CL SpO2 Pod is not in its cradle. The temperature of the battery in the CL SpO2 Pod is too high. Remove the CL SpO2 Pod from the patient and contact service personnel. The battery in the CL SpO2 Pod has reached the end of its useful life. It can no longer be charged. Contact your service personnel to replace the battery. What to do The thermometer requires calibration. Contact your service personnel. The thermometer firmware is not supported by the monitor software. The thermometer or the interface board is defective. Check the thermometer on another monitor - if the same INOP occurs, replace the thermometer. If not, connect another thermometer to this monitor. If the problem persists, the interface board has a problem. Contact your service personnel. The ambient temperature is out of range. If the ambient temperature is within the valid range, check the thermometer. Try picking up a new probe cover. If the problem persists replace the thermometer and contact your service personnel. The measured temperature is out of range. If the temperature is within the valid range, check with another thermometer. 8 8Admitting and Discharging The fetal monitor can store basic patient demographic information used to identify patients. Admit/Discharge on the Monitor This section describes how you admit and discharge patients when using the monitor as a stand-alone device (that is, when not used with an obstetrical information and surveillance system such as OB TraceVue/IntelliSpace Perinatal). Admitting a Patient The fetal monitor displays physiological data as soon as a patient is connected. This lets you monitor a patient who is not yet admitted. It is however important to admit patients properly so that you can identify your patient on recordings. Use the Patient Demographics window and its associated pop-up keys to admit and discharge patients. To admit a patient:
1 Select the patient name field or select the Patient Demogr. SmartKey to open the Patient Demographics window. 2 Clear any previous patient data by selecting Dischrge Patient and then Confirm. If you do not discharge the previous patient, you will not be able to distinguish data from the previous and current patients on the recording. Select Admit Patient. 3 4 Enter the patient information: select each field and use the on-screen keyboard. Last Name: Enter the patient's last name (family name), for example Doe. First Name: Enter the patient's first name, for example Jane. If a conventional keyboard is connected to the monitor, you can use this to enter patient information:
MRN: Enter the patient's medical record number (MRN), for example 12345678. Depending on your configuration this field may be labeled differently e.g. Record ID, Lifetime ID, Account Number, Serial Number, or SSN. Gestational Age: Enter the gestational age of the pregnancy. Enter one numeric for the week
(0-50) and one numeric for the day (0-6). 5 Date of Birth: Enter the patient's date of birth. Select Confirm. The patient status changes to admitted. If the recorder is running, the recorder stops and immediately restarts to annotate the new patient data. 147 8 Admitting and Discharging Quick Admitting a Patient Use Quick Admit to quickly admit a patient using only a limited set of demographic data. 1 2 Enter the required data (ID fields or last name depending on configuration) with the keyboard or a Select the Quick Admit SmartKey. barcode scanner. Select Enter. In the confirmation window, select Confirm to stop monitoring for the previous patient. 3 4 Complete the rest of the demographic details as soon as possible to fully identify the patient on the network, on the monitor, and on printed reports. To complete the details, open the Patient Demographics window and complete all required fields. Editing Patient Information To edit the patient information after a patient has been admitted, select the patient name field on the main screen of the fetal monitor to open the Patient Demographics window, and enter the required changes. Discharging a Patient You should always perform a discharge even if your previous patient was not admitted. A discharge:
clears the information in the Patient Demographics window. resets all monitor settings to the settings defined in the User Defaults. advances the paper automatically if the recorder is running. stops the fetal recorder. When a patient is discharged from the monitor, all patient demographic data is deleted (trace data is not affected). Depending on your configuration, monitoring for a patient may end automatically when the fetal monitor has been powered off, or is in Standby mode for a set time. To discharge a patient:
1 Select the patient name field to display the Patient Demographics window and associated pop-up keys. Select the pop-up key for Dischrge Patient. Select Confirm to discharge the patient. 2 3 CAUTION In order to ensure that the settings are reset to User Defaults for a new patient, always discharge the previous patient from the fetal monitor. NOTE In order to ensure a continuous record, it is recommended to discharge the patient at the monitor before performing a new patient admission in OB TraceVue/IntelliSpace Perinatal. 148 8 Admitting and Discharging New Patient Check after a specified power-off period after a specified standby period The fetal monitor can be configured to ask you in certain situations:
whether a new patient is now being monitored. The pop-up window is entitled Is this a New Patient?. The monitor offers a Yes key, to discharge the previous patient and begin monitoring a new patient, and a No key, to continue monitoring with the current patient data and settings. The time periods for the two conditions can be configured independently. OB TraceVue/IntelliSpace Perinatal When the monitor is connected to an OB TraceVue/IntelliSpace Perinatal system over a LAN connection, it has the control over patient demographic data. All patient and location-related data visible on the monitor is set, overwritten, or updated by the OB TraceVue/IntelliSpace Perinatal system. In the Patient Demographics window, a padlock symbol before the patient identification fields indicates the locked state. The locked state prevents the reuse of the monitor for another patient, until the current patient is discharged, and the monitor is freed through the OB TraceVue/IntelliSpace Perinatal system. Locked fields remain locked when system connectivity is lost, until the monitor is freed by discharging the patient. See the OB TraceVue/IntelliSpace Perinatal Instructions for Use for details. Transferring a Patient When you are transferring a patient from one bed to another, both the monitor from which you are transferring her and the monitor to which you are transferring her must be switched on and connected to the OB TraceVue/IntelliSpace Perinatal network during the patient transfer. 149 8 Admitting and Discharging OB TraceVue/IntelliSpace Perinatal via RS232 In contrast to a LAN connection, when the monitor is connected to an OB TraceVue/IntelliSpace Perinatal system over an RS232 connection, the OB TraceVue/IntelliSpace Perinatal system does not have full control over the monitor's patient admission and discharge functions. Depending on how OB TraceVue/IntelliSpace Perinatal is configured, either the Last Name, First Name, and the bed label, or just the bed label alone, are taken from the OB TraceVue/IntelliSpace Perinatal system. See the OB TraceVue/IntelliSpace Perinatal Instructions for Use for details. 150 9 9Non-Stress Test Timer The non-stress test (NST) timer shows the elapsed time for the non-stress test. The timer counts up to the time you set for the NST. Setting NST Autostart/Autostop You can set the recorder so that it starts automatically (NST Autostart) when the NST timer is started, and stops automatically (NST Autostop) when the NST is complete (when the set run time has elapsed). As default, NST Autostart is On, and NST Autostop is Off. Viewing the NST Timer You can configure the timer notification symbol, (the NST label), a progress bar and the elapsed time to be displayed in the top left-hand corner of the screen. By default, the NST timer is not displayed on the screen. Alternatively, you can view the timer in the Timers window. To open the Timers window:
Either Or Access the NST pop-up keys (see Accessing the NST Setup Pop-up Keys on page 152), and Press the Timer SmartKey. press the Timers key. Timer Expiry Notification When the timer expires, the color changes from blue to green, you hear a single tone, and a message appears in the status line on the main screen. The volume of the tone can be set in Configuration Mode. 151 9 Non-Stress Test Timer Accessing the NST Setup Pop-up Keys You control and set up the NST timer (for example, start, stop, or clear the timer, and set the run time) using a selection of pop-up keys that you access via any one of three possible routes:
Via the Timer SmartKey (Route 1) Via the Main Setup SmartKey (Route 2) Via the NST display area at the top left-hand corner of the screen (Route 3). When you touch the NST display area, the NST pop-up keys become available at the bottom of the screen. Via the Timer SmartKey (Route 1) Press the Timer SmartKey. The Timers window opens, and the pop-up keys for controlling/setting up the NST timer appear (see Pop-up Keys for NST Timer Setup on page 152). Via the Main Setup SmartKey (Route 2) 1 Enter the Main Setup menu using the SmartKey. 2 Select NST to enter the Setup NST menu. At the same time, the pop-up keys for setting up the NST timer appear (see Pop-up Keys for NST Timer Setup on page 152). Via the NST Display Area (Route 3) Select the NST display area at the top left-hand corner of the screen (when so configured). The pop-up keys for controlling/setting up the NST timer become available at the bottom of the screen (see Pop-
up Keys for NST Timer Setup on page 152). Pop-up Keys for NST Timer Setup Pop-Up Keys Start Stop Setup NST Selecting this pop-up key lets you:
Start the timer. Stop the timer, allowing either restarting after a pause (Start) or clearing (Clear key). Enter the Setup NST menu. From here you can set the run time. Timer Return to the Timers window. Comments This pop-up key is not available with Route 2, as the Setup NST menu is already open. This pop-up key is not available with Route 1, as the Timers window is already open. Runtime The run time can be set from 10 to 60 minutes. See the Configuration Guide for details how to set the run time. Run Time The run time can be set from 10 to 60 minutes. See the Configuration Guide for details how to set the run time. 152 10 10Non-Stress Test Report It is generally accepted that a non stress test (NST) allows you to assess fetal well-being. The monitor's NST report process uses fetal ultrasound (but not DECG) heart rate traces and the Maternal Toco trace to generate a printed report when criteria are met and it is an indication of the fetal well-being. The American term Non Stress Test (NST) is used for antepartum testing. The interpretation algorithm and rule set are equivalent to those implemented in OB TraceVue Revision G.xx or IntelliSpace Perinatal Revision H.xx and higher, and are based on the 2008 NICHD guidelines. An NST report is a diagnostic aid, but it does not replace the clinicians judgment. The interpretation and the appropriate clinical response remain with the clinician. A fetus normally produces characteristic heart rate patterns. Average baseline variability and acceleration of the FHR in response to fetal movement are considered reassuring signs. This test does not take into account any form of external fetal stimulation. For every active ultrasound fetal heart rate measurement, one NST report can reside in the monitors memory. The reports are cleared when you discharge a patient and when you start a new NST report. When the NST Report option is available and the NST Report feature is "on", the NST status for all available ultrasound fetal heart rate measurements are displayed on the screen. The minimum displayed information is:
NST identification (by FHR number: 1, 2, 3) Current NST status (by color: inverse for "not started yet", white for "running", yellow for
"stopped", green for "finished") Setting Up an NST Report To set up NST Report functionality:
1 Enter the Main Setup menu and select the NST Report. 2 Or select the NST Report SmartKey. 3 Press the Setup pop-up key. 153 10 Non-Stress Test Report Set your configuration options. 4 Select from:
NST Analysis choose from On or Off. This switches the report feature on or off. This is linked to the NST timer. Both must be set to On for the NST report to function. Report Recording choose from:
Manual - press the Record Report pop-up key to trigger a manual request. After Recorder Stop - report is recorded as soon as recorder becomes idle. Immediately - if a realtime recording is running, the monitor pauses it. The recording is continued after the report has been recorded. Average short term variability (STV) value is documented in [bpm] and [ms] if STV is configured as part of the NST Report. This parameter is not considered as reassuring criteria. NST Report Status Window The NST Report window displays a detailed overview of the current NST status for any available ultrasound fetal heart rate measurement. You can see:
NST Status - whether it is ready, ongoing, or the time and date at which it was stopped, or at which it was finished. Baseline - the average baseline value. Short Term Variability - the current short term variability (STV) value. FHR Availability - current statistical FHR availability value. Sinusoidal - the current status of sinusoidal rhythm detection. Elapsed time - the time that has elapsed since the NST began. Accelerations - the number of FHR accelerations detected so far. Variability - the average variability value. Decelerations - the number of FHR decelerations detected so far. For criteria not yet met, a white arrow symbol marks the overall status on the top line, and also appears against every criterion not yet met. A yellow symbol indicates detection of severe or prolonged decelerations. The pop-up keys let you perform the following actions:
FHR1, FHR2, FHR3 - switch to the window showing the current NST status for the fetal heart rate. Record Report - print the NST Report on paper. Record Trace - record the trace episode that belongs to the current report. Depending on device usage, the trace recording might be incomplete. Setup - open the Setup NST Report window. 154 Example NST Report 10 Non-Stress Test Report Field Report Title, with FHR label and date Product Information Patient Information Start time, end time, Elapsed time, configured runtime Overall one-line NST result summary Title Result Accelerations Result: Contractions Result: Baseline and Variability Statistics: FHR availability Result: Decelerations Field Content NST Report for FHR1 on 12 Oct. 2009 Product DE53102345 G.01.70, OB A.04.24, Toco DE52401090, FHR1 DE00002345 A.05.26 Rogers, Alice Age: 27 Gestational Age: Week 34, Day 5 Time: 11:34 12:06 Elapsed time: 32 min Run time: 20 min NST Criteria*: not met Trace Interpretation Summary Accelerations: 2 at: 11:59 12:02 Contractions: 3 at: 11:57 12:00 12:04 Baseline: 125 bpm (Range: 118-129 bpm) Variability: 23 bpm (Range: 20-24 bpm) FHR available: 95%

(*) Interpretation criteria based on guideline "NICHD 2008, v01"
User-defined criteria for CTG tracing:
moderate baseline variability (6-25 bpm) Additional criteria:
no severe or prolonged decelerations no sinusoidal pattern in reporting period Guideline/Criteria Information 156 NST Criteria 10 Non-Stress Test Report The patient is monitored for a user-definable period of time (10-60 minutes in steps of 5 minutes). The test is considered reassuring when the following criteria are met:
The fetal heart rate is valid at least 90% (this is configurable) of the specified time span. The FHR features a user-defined minimum number of accelerations. The FHR features a user-defined maximum number of tolerated decelerations, and does not include severe or prolonged decelerations, which are never tolerated. The average baseline fetal heart rate lies within the user-defined limits for low heart rate and high heart rate over the whole time span. The FHR exhibits a moderate variability (user-defined) for the specified time span. An NST Report is generated when the reassuring criteria are met the first time in the current monitoring phase. When performing NST with twins or triplets, a separate NST Report is generated for each fetus. After the reassurance criteria have been met, the clinician can print the NST Report and then turn the fetal monitor off, or may continue fetal monitoring and print the report at any time. Non-Reassuring Report If the reassurance criteria are not met when the test has run for 90 minutes, or if you stop anytime during the 90 minute period, then the test is stopped, and a report is generated stating the reassurance criteria have not been met. Nonreactive NST Test If a nonreactive test occurs, and you then use acoustic stimulation, you must exercise caution in interpreting the resulting traces, as artificial stimulation is not taken into account when calculating test results. 157 10 Non-Stress Test Report 158 11 11Cross-Channel Verification
(CCV) The cross-channel verification helps to reduce the possibility of misidentification of the maternal heart rate for the fetal heart rate. It does this by comparing the measured fetal heart rate to the maternal heart rate. If there are multiple fetal rates, they are also compared with each other and the maternal heart rate. Misidentification of Heart Rates FHR detection by the monitor may not always indicate that the fetus is alive. Confirm fetal life before monitoring, and continue to confirm that the fetus is the signal source for the recorded fetal heart rate
(see Confirm Fetal Life Before Using the Monitor on page 10). To reduce the possibility of mistaking the maternal HR or pulse for FHR, or FHR1 for FHR2 or FHR3, it is recommended that you monitor both maternal HR/pulse and the heart rates of all fetuses
(see Monitoring FHR and FMP Using Ultrasound on page 165, Monitoring Twin FHRs on page 183, Monitoring Triple FHRs on page 191, and Monitoring Maternal Heart / Pulse Rate on page 221). Here are some examples where the maternal HR can be misidentified as the FHR, or one FHR for another FHR (twins/triplets). When using an ultrasound transducer:
It is possible to pick up maternal signal sources, such as the maternal heart, aorta, or other large vessels. Especially if the recorded maternal HR, and any other artifact is over 100 bpm. It is possible to pick up the same fetal heart rate simultaneously with multiple transducers. NOTE When an ultrasound transducer is connected to the monitor, but not applied to the patient, the measurement may generate unexpected intermittent FHR readings. 159 11 Cross-Channel Verification (CCV) When Fetal Movement Profile (FMP) is enabled:
The FMP annotations on a fetal trace alone may not always indicate that the fetus is alive. For example, FMP annotations in the absence of fetal life may be a result of:
Movement of the deceased fetus during or following maternal movement. Movement of the deceased fetus during or following manual palpation of fetal position (especially if the pressure applied is too forceful). Movement of the ultrasound transducer. When using a scalp electrode (DECG):
Electrical impulses from the maternal heart can be transmitted to the fetal monitor through a recently deceased fetus via the spiral scalp electrode, appearing to be a fetal signal source. Cross-Channel Verification Functionality The cross-channel verification functionality (CCV) of the fetal monitors compares all monitored heart rates (maternal and fetal), and indicates automatically whether any two channels are picking up the same signal, or monitoring similar values. If the fetal monitor detects that any channels have the same or similar values, the Coincidence INOP is issued with an INOP tone that can have a configurable delay. In addition, yellow question marks appear next to the numerics on the touchscreen that have the same or similar values. On the recording trace there is also a question mark from the point where recorded traces continuously overlap. Visual Aids for CCV Detection Coincidence INOP appears on the screen of the fetal monitor. Question mark appears on the screen of the fetal monitor next to the numerics that show the same or similar values. Question mark recorded on the trace from the point where two measured values coincide. 160 Overview of Cross-Channel Comparisons 11 Cross-Channel Verification (CCV) Measurements from Transducers Measurement FHR (US) dFHR (DECG) aFHR (abdom.

* dFHR and aFHR always replace one of the fetal channels (1,2, or 3) and cannot be compared to the channel it replaces. If you monitor for example twins with two ultrasound transducers, you see the numerics FHR1 and FHR2 at the monitor. If you decide to replace the ultrasound transducer for FHR2 with a fetal scalp electrode, the dFHR numeric is then shown as dFHR2. 161 11 Cross-Channel Verification (CCV) Coincidence Examples Coincidence of Maternal Pulse and FHR When the maternal pulse and FHR are being monitored, and the measured values are very similar or the same, the coincidence question mark is displayed on the monitors screen above both of the corresponding numerics (in this case maternal pulse and FHR). Often the signal loss or coincidence happens because the fetal or maternal movement displaced the ultrasound transducer, and a repositioning of the transducer is necessary. Coincidence INOP 1 2 Coincidence question mark above FHR1 3 Coincidence question mark above pulse from Toco MP Pulse Delay SpO2 pulse rate traces have an averaging calculation of approximately 10 seconds and an overall delay of approximately 12 seconds (depending on recorder speed). This differs from a non-averaged beat-to-
beat MECG heart rate trace or an ultrasound heart rate trace calculation (having switched to the maternal HR) with no significant delay. Note that Maternal Pulse from Toco has an averaging of 4 seconds and an overall delay of between 6 and 8 seconds. 162 11 Cross-Channel Verification (CCV) The coincidence question mark is also printed on the trace paper next to the corresponding FHR and maternal pulse. 1 2 Printed coincidence question mark on trace Fetal heart rate trace from Ultrasound 3 Maternal pulse trace from SpO2 Coincidence of Twins/Triplets FHRs When both FHR1 and FHR2 are being monitored, and the measured values are very similar or the same, the coincidence question mark is displayed on the monitors screen above both of the corresponding numerics (in this case FHR1 and FHR2). Coincidence INOP 1 2 Coincidence question mark above FHR1 3 Coincidence question mark above FHR2 163 11 Cross-Channel Verification (CCV) The coincidence question mark is also printed on the trace paper next to FHR1 and FHR2. 1 2 Printed coincidence question mark on trace FHR1 and FHR2 traces Recommended Actions for Coincidence INOP 1 Confirm fetal life by palpation of fetal movement or auscultation of fetal heart sounds using a fetoscope, stethoscope, or Pinard stethoscope. 2 Manual determination of the maternal pulse and comparison with the fetal heart rate sound signals from the loudspeaker. 3 Reposition the transducer, or ensure that the fetal scalp electrode is placed correctly, until you receive a clear signal and the monitor is no longer issuing the Coincidence INOP. In case of difficulties deriving a stable maternal pulse reading using the Toco MP or CL Toco+ MP transducer, use SpO2 or the CL SpO2 Pod instead. In case of similar problems with the pulse measurement from SpO2, use MECG instead. Reasons to switch the method for deriving a maternal pulse or heart rate include: motion artifacts, arrhythmia, and individual differences in pulse signal quality on the abdominal skin (via Toco MP). If you cannot hear the fetal heart sounds, and you cannot confirm fetal movement by palpation, confirm fetal life using obstetric ultrasonography. 4 5 164 12 12Monitoring FHR and FMP Using Ultrasound To monitor a single FHR externally, you use an ultrasound transducer attached to a belt around the mother's abdomen. The ultrasound transducer directs a low-energy ultrasound beam towards the fetal heart and detects the reflected signal. Your monitor can also detect fetal movements and print the fetal movement profile (FMP) on the trace. Monitoring using ultrasound is recommended from the 25th week of gestation for non-stress testing or routine fetal monitoring. WARNING Performing ultrasound imaging or Doppler flow measurements together with ultrasound fetal monitoring may cause false FHR readings, and the trace recording may deteriorate. Technical Description Fetal monitors use the ultrasound Doppler method for externally monitoring the fetal heart rate. Using the Doppler method, the transducer (in transmitter mode) sends sound waves into the body which are then reflected by different tissues. These reflections (Doppler echoes) are picked up by the transducer
(in listening mode). These Doppler echoes are amplified and sent to the monitors speaker through which the fetal heart signal can be heard. In parallel the Doppler echoes are processed through an autocorrelation algorithm to determine the fetal heart rate (FHR). The FHR is displayed on the monitors numeric display and on the recorded trace. Properly representing the fetal heart rate using a device that derives heartbeats from motion is a formidable task and the limitations of the technology will be discussed shortly. Basic fetal cardiac physiology may contribute to difficulties in obtaining a reliable ultrasound signal. A heart rate pattern of a fetus is capable of extraordinary variation, ranging from a stable pattern with minimal variation while the fetus is asleep to robust accelerations of 40-60 bpm above baseline rate over a few seconds, or exaggerated variability when the fetus is active. Decelerations of the rate 60-80 bpm below baseline may develop even more abruptly than the accelerations. Beat-to-beat arrhythmias may further exaggerate the amount of variability and can be seen at the bottom of variable decelerations, or in the presence of fetal breathing movements which also tend to lower the fetal heart rate. The recognition of these normal variations in fetal heart rate patterns will greatly assist in the separation of genuine fetal information from the artifact. 165 12 Monitoring FHR and FMP Using Ultrasound Limitations of the Technology All tissues moving towards or away from the transducer generate Doppler echoes. Therefore, the resulting signal that is provided to the monitors speaker, and for further fetal heart signal processing, can contain components of the beating fetal heart wall or valves, fetal movements, fetal breathing or hiccup, maternal movements such as breathing or position changes, and pulsating maternal arteries. The fetal heart signal processing uses an autocorrelation algorithm to obtain periodic events such as heart beats. If the signal is erratic such as from a fetal arrhythmia, the ultrasound device may have trouble tracking the abrupt changes, and may misrepresent the true FHR pattern. Signals such as those from moving fetal limbs are usually very strong, thereby masking the fetal heart signal. During prolonged movements where the fetal heart signal is masked, the FHR appears blank on the numeric display and as a gap on the recorded trace. Fetal position changes, maternal position changes, or uterine contractions can move the fetal heart partly or fully out of the ultrasound beam resulting in signal loss, or even picking up Doppler echoes from pulsating maternal arteries. In these cases a maternal heart rate or sometimes even a rate resulting from the mixture of fetal and maternal signals may be displayed on the monitors numeric display and on the recorded trace. In contrast to the timely well-defined R-peak of an ECG signal obtained with a fetal scalp electrode, the ultrasound Doppler signal from a fetal heart consists of multiple components from atria (diastole), ventricles (systole), valves, and pulsating arteries. These components vary depending on fetal and transducer position and angle, and are further modulated by factors such as fetal or maternal breathing. These effects may produce what is called artifact. Optimal transducer positioning therefore is key to minimizing these effects and thereby minimizing artifact. Misidentification of Maternal HR as FHR FHR detection by the monitor may not always indicate that the fetus is alive. Confirm fetal life before monitoring, and continue to confirm that the fetus is the signal source for the recorded heart rate (see Confirm Fetal Life Before Using the Monitor on page 10 and Cross-Channel Verification (CCV) on page 159). What You Need Toco MP or CL Toco+ MP transducer Ultrasound transducer Ultrasound gel Transducer belt (and optional butterfly belt clip, if applicable) 166 Cableless Monitoring - Important Considerations 12 Monitoring FHR and FMP Using Ultrasound When using an Avalon CL or Avalon CTS Fetal Transducer system with your monitor, note the following:
Refer to Cableless Status Indication on page 95 for general rules regarding the use of cableless transducers from an Avalon CL or Avalon CTS Cableless Fetal Transducer system. CAUTION Never use ultrasound transducers connected to more than one fetal monitor on the same patient. When using an Avalon CL or Avalon CTS you should be aware that FMP is not recommended when the mother is likely to move, and you should disable Fetal Movement Profile (FMP) on the fetal monitor (Fetal Movement Off) if the mother is walking. See also Fetal Movement Profile on page 170. With the Avalon CL Transducer System, you can monitor twins and triplets with cableless transducers. The Avalon CTS System does not have this option. The wireless symbol appears next to the measurement label, indicating that the measurement is being made by a cableless transducer. FHR1 1 2 Toco parameter 167 12 Monitoring FHR and FMP Using Ultrasound WARNING During ambulant FHR monitoring, the chance of losing the signal or detecting the maternal heart rate is higher than during stationary monitoring. The frequency of the patient's walk may be detected, and mistaken for an FHR signal. Check the mothers pulse periodically during monitoring and compare this with the FHR signal. Beware of mistaking a doubled maternal heart rate for FHR. If a fetus is dead, there is a risk that the maternal heart rate is monitored and misinterpreted as the fetal heart rate. Therefore, the simultaneous monitoring of maternal heart rate (preferably, the maternal ECG) and the fetal heart rate is encouraged. Do not interpret maternal movements as fetal movements. Artifacts: FMP artifacts are generated during fetal heart rate searching by changing the transducer position, therefore the fetal monitors enable the FMP only after detecting a valid heart rate signal for several seconds. FMP is not recommended when the mother is likely to move, and you should disable Fetal Movement Profile (FMP) at the fetal monitor (Fetal Movement Off) if the mother is walking. Gaps in maternal heart rate detection can occur:
if the transducer is not correctly positioned. due to the pulsation of uterine blood vessels. if the fetus moves. Preparing to Monitor Prepare for ultrasound monitoring using the list below. The standard procedures in use in your facility determine the sequence of actions. 1 Determine fetal position. 2 3 4 Connect the transducer to a free socket. The signal quality indicator for the heart rate initially Fasten the belt around the patient. Switch on the monitor and the recorder. displays an invalid signal. 5 Apply a thin layer of ultrasound gel to the underside of the transducer. CAUTION Using ultrasound gel not approved by Philips may reduce signal quality and may damage the transducer. This type of damage is not covered by warranty. 1 Place the transducer on the abdomen, if possible over the fetal back or below the level of the umbilicus in a full-term pregnancy of cephalic presentation, or above the level of the umbilicus in a full-term pregnancy of breech presentation. Work the transducer in a circular motion to ensure the gel layer makes good contact. 2 When the transducer is connected correctly and you receive a good signal, the signal quality indicator should be filled out. If an inadequate signal is produced, the signal quality indicator will indicate a poor signal, and no numeric will appear on the screen. 168 12 Monitoring FHR and FMP Using Ultrasound 3 Adjust the audio volume of the monitor's loudspeaker to a clearly audible level, while moving the transducer over the abdomen. When you have a good signal, secure the transducer in position below the belt. WARNING Periodically compare the mother's pulse with the signal coming from the monitor's loudspeaker to ensure that you are monitoring fetal heart rate. Do not mistake a doubled or elevated maternal HR for FHR. The ultrasound transducer may warm slightly (less than 1C/1.8F above ambient temperature) when applied to the patient. When not applied, the transducer can reach a maximum temperature of 44C/
112.2F at an air temperature of 40C/104F. Selecting Fetal Heart Sound You can listen to the fetal heart sound from one ultrasound transducer at a time. When the fetal heart sound is selected for an FHR channel, you see the audio source symbol next to the FHR numeric label for that channel. FHR1 1 2 Audio source symbol To select the audio source for an FHR channel:
1 Enter the Setup FHR1 menu for the channel you want to hear (FHR1 used as an example). 2 Press Select Audio. It may take a few seconds for the audio source symbol to appear. 169 12 Monitoring FHR and FMP Using Ultrasound Changing the Fetal Heart Sound Volume The FHR volume symbol at the top right of the Fetal Heart Sound Volume window gives you an indication of the current volume. To change the volume:
1 Select the volume symbol. The volume scale pops up. 2 Select the required volume from the volume scale. 1 Fetal Heart Sound Volume Fetal Movement Profile The Fetal Movement Profile (FMP) parameter detects fetal movements with an ultrasound transducer connected to the monitor. Only the fetus monitored on the FHR1 channel is monitored for FMP. Once you have enabled FMP (see Switching FMP On and Off on page 171), it is triggered automatically whenever:
You connect an ultrasound transducer. A patient is discharged. When FMP is enabled, the ultrasound transducer detects most fetal body movements. Eye movements are not detected, and movement of the feet and hands may not be detected. Positioning or repositioning of the transducer is recorded as fetal movement. Maternal movement, excessive fetal breathing, or fetal hiccups may also be recorded as fetal movement (also in case of fetal demise or during the second stage of labor). You can mark these artifacts on the trace paper using either the remote event marker, or the event marker key as described in Marking an Event on page 60. FMP should be interpreted with care, or disabled when the patient is ambulating or during the second stage of labor. Ignore these movements when you interpret the FMP. When monitoring twins or triplets, only the fetus monitored on the FHR1 channel is monitored for movement, but be aware that movements recorded for FHR1 may also be caused by movement of the second or third fetus. The fetal movement profile (FMP) appears as "activity blocks" along the top of the Toco scale, the length of each block showing the duration of the activity. 170 12 Monitoring FHR and FMP Using Ultrasound FMP Statistics FMP statistics are printed every ten minutes. 1 2 A B C FMP enabled FMP started here Indication of current fetal movement The FMP statistics are presented as two percentage figures:
The first figure shows the percentage of detected fetal movements in the previous ten minutes. The second figure shows the percentage of detected fetal movements since the start of recording. To mark the start of the FMP statistic, FMP is printed on the paper with an arrow. The FMP detection activates after about half a minute of steady heart rate signals (signal indicator half-
full, or full) to minimize transducer positioning artifact. You will notice this deliberate delay:
When a new patient is admitted. A patient discharge restarts the FMP statistics from zero. When you connect an ultrasound transducer. Switching FMP On and Off You can switch FMP on and off from any FHR channel. For example, to set it from the FHR1 channel:
1 Enter the Setup FHR1 menu. 2 3 Return to the main screen. Select Fetal Movement to switch between On and Off. 171 12 Monitoring FHR and FMP Using Ultrasound Troubleshooting Problem Erratic trace Erratic display Possible Causes Fetal arrhythmia Obese patient Transducer position not optimal Belt loose Too much gel Very active fetus Insufficient gel Signal quality indicator is continuously poor Transducer position not optimal FHR less than 50 bpm (and the FHR is audible) Questionable FHR Recording maternal HR by mistake Recording periodic signals when the transducer is not applied to the patient Recorded FHR appears to be suspiciously higher, or suspiciously lower, than real FHR. In very rare cases, half- or double-counting of the FHR can occur. Solutions Consider monitoring FHR using DECG after the rupture of membranes. Reposition transducer until signal quality indicator shows a good signal (at least half-full). Tighten belt Remove excess
-
Use enough gel to ensure the transducer makes good contact with the mother's skin. Reposition transducer until signal quality indicator shows a good signal (at least half-full). If membranes are ruptured, using a fetal scalp electrode (FM30 and FM50 only) allows measurement of FHR down to 30 bpm. Reposition transducer Confirm fetal life Disconnect all NON-USED ultrasound transducers, as continuous, regular mechanical, or electromagnetic influences can result in an artificial trace. If you have reason to question the validity of the recorded FHR, always verify FHR by independent means (by auscultation, for example). Measure maternal pulse by independent means. FHR not recorded FHR is less than 50 bpm or over 240 bpm If membranes are ruptured, using a fetal scalp electrode (FM30 and FM50 only) allows measurement of FHR down to 30 bpm. If FHR is outside of the specified range, verify FHR by independent means. FHR1 Equip Malf or FHR2 Equip Malf or FHR3 Equip Malf INOP displayed.

If you suspect the transducer is malfunctioning Test the transducer. page 129. 172 12 Monitoring FHR and FMP Using Ultrasound Testing Ultrasound Transducers If any of the following tests fail, repeat the test using another transducer. If the second transducer passes the tests, confirming that the first transducer is defective, contact your service personnel. If the second transducer also fails the tests, contact your service personnel. To test an ultrasound transducer:
1 Switch on the monitor and the recorder. 2 Connect the transducer to the fetal 3 4 monitor. Select the fetal heart sound for this channel. Increase the loudspeaker volume to an audible level. 5 Holding the transducer in one hand, move your other hand repeatedly towards and then away from the surface. 6 Check that a noise is heard from the loudspeaker. You can test all ultrasound transducers, including the cableless ones, as described above. Additional Information Artifact in Fetal Heart Rate Measurement How to detect it and reduce its occurrence using the Avalon Fetal Monitor The ultrasound derived FHR measurement technique in Avalon fetal monitors, like all other ultrasound fetal monitors FHR measurement techniques, has limitations that can lead to misrepresentation of the fetal heart rate pattern and potential misinterpretation of the fetal condition. An incorrect interpretation of the trace may lead to either unnecessary interventions, or to failure to detect fetal distress, and the need for intervention. Thus, the on-going evaluation of the recorded trace requires regular confirmation that the trace represents the true FHR. Specific situations requiring such confirmation include the following:
After starting a measurement or changing a transducer After maternal position changes, for example during pushing with contractions When the tracing shows abrupt changes in baseline rate, variability, or pattern (decelerations to accelerations) especially in the second stage of labor When the baseline maternal heart rate is within about 15 bpm of the FHR 173 12 Monitoring FHR and FMP Using Ultrasound When you are unable to determine a baseline rate, and variability occurs between consecutive contractions There are several ways to verify the source and/or accuracy of the recorded fetal heart rate pattern. These include:
Verification of the FHR with:
An obstetric stethoscope Ultrasound imaging A fetal scalp electrode Verification of the maternal heart rate:
Using pulse oximetry - for a maternal heart rate pattern displayed simultaneously with the FHR
(Cross-Channel Verification (CCV) feature) Using Maternal ECG - for a maternal heart rate pattern displayed simultaneously with the FHR
(CCV feature) Manual determination of the maternal pulse Whenever possible measure the maternal pulse rate to make use of the monitors Cross-Channel Verification (CCV) feature, especially during the second stage of labor, or when the maternal pulse is elevated over 100 bpm. The Avalon fetal monitor provides a Toco MP or CL Toco+ MP transducer for maternal pulse detection and the creation of a maternal heart rate pattern plotted on the same recorder as the FHR pattern. In case of difficulties deriving a stable maternal pulse reading using the Toco MP or CL Toco+ MP transducer, use SpO2 or MECG instead. When either of these parameters is utilized, the monitor will automatically and continuously perform a CCV of the maternal heart rate pattern against the FHR pattern displayed on the monitor. If the patterns and rates are similar, the CCV provides an alarm that both rates are probably from the same source (i.e., they both represent the maternal heart rate pattern and the fetus is not being monitored). Repositioning the ultrasound transducer will usually correct this, but it may be necessary to apply a fetal scalp electrode. Advising the mother to temporarily cease pushing during contractions may help to more rapidly resolve any uncertainty in this situation. Doubling: The autocorrelation algorithm can display a doubled fetal or maternal heart rate if the duration of diastole and systole are similar to each other, and if the heart rate is below 120 bpm. Doubling, usually brief, is accompanied by an abrupt switch of the trace to double the baseline value. Halving: With fetal tachycardia (above 180 bpm) and some interference from breathing or maternal arteries the autocorrelation algorithm may only recognize every second beat resulting in a halved rate for a limited time. If the actual FHR is above the maximum limit of the monitor (240 bpm), the algorithm will also half-count. Halving is accompanied by an abrupt switch of the trace to exactly half the prior baseline value. This switch may simulate an FHR deceleration and be referred to by clinicians as a false deceleration. Switching to maternal heart rate (also referred to as "Maternal Insertion"): The fetal heart can move partly or fully out of the ultrasound beam and the autocorrelation algorithm may then pick up and display the maternal heart rate. Depending on the signal mix in the ultrasound signal, switching to the maternal heart rate may mimic several conditions with the potential for erroneous interpretation and response as follows:
The switch to the maternal heart rate may simulate an FHR deceleration (i.e., a decrease of the fetal heart rate, and be referred to by clinicians as a false deceleration). 174 12 Monitoring FHR and FMP Using Ultrasound The maternal heart rate may simulate a normal fetal heart rate pattern (i.e., it may mask an FHR deceleration or fetal demise). Especially during pushing with contractions in the second stage of labor, the maternal heart rate may increase to the point where it may equal or exceed the fetal rate. Here the maternal trace may mimic a normal fetal trace while the fetus may be having decelerations or fetal demise has occurred. This change from fetal to maternal heart rate pattern may not be at all obvious unless CCV is used and represents the most dangerous pitfall of all the artifacts because fetal distress may go unrecognized. The maternal heart rate may simulate an FHR acceleration, which is an increase of the fetal heart rate. During expulsive efforts, the maternal heart rate normally accelerates and may be at or above the normal FHR range. The FHR may display gradual appearing decelerations. Generally, the false decelerations described above are abrupt. Rarely, combinations of noisy/erratic signal associated with changes in maternal and/or fetal rate or movement will produce more gradual appearing false decelerations but these are usually short-lived with an abrupt return to an obviously stable FHR baseline. Noisy/Erratic signals: With mixed or weak signals the tracing may reveal very brief episodes of erratic recorded traces. These represent the autocorrelation algorithm finding brief sequences of apparent and persistent heartbeats amidst a mixed or weak signal. These erratic recorded traces are commonplace, especially in association with fetal or maternal movement. During prolonged periods of such noisy/erratic signals, the fetus is not being adequately monitored. Drop out: With mixed or weak signals there may be no heart rate tracing at all. These episodes reflect that if the algorithm does not find an apparent and persistent heartbeat amidst a mixed or weak signal, it will not print a heart rate on the tracing. Brief episodes of drop out are commonplace, especially in association with fetal or maternal movement. During prolonged periods of drop out, the fetus is not being adequately monitored. Multiple Fetuses With multiple fetuses, the potential to experience these artifacts is increased. Positioning of the transducer is even more critical. Ultrasound scanning should be used to help with positioning of individual transducers. See also Monitoring Twin FHRs on page 183 and Monitoring Triple FHRs on page 191. 175 12 Monitoring FHR and FMP Using Ultrasound Obtaining a Good Heart Signal To successfully position the ultrasound transducer, first determine the fetal position using palpation. Position the transducer over the strongest audible fetal heart sound from the monitors speaker and wait at least six seconds after each transducer adjustment to verify a good signal quality displayed on the Signal Quality Indicator and a consistent FHR numeric display. Having determined the position that provides a strong fetal signal, fix the transducer on the abdomen with the belt. If the quality of the signal or the appearance of the heart rate trace from the ultrasound transducer is questionable, the transducer should be repositioned as described above. Alternatively, the use of an ultrasound scanner will greatly facilitate the determination of the optimal site for the ultrasound heart rate transducer. Factors during the second stage of labor that may influence the quality of the FHR tracing obtained with ultrasound include:
Uterine contractions Changing contour of the maternal abdomen Maternal body movement - positioning Maternal expulsive efforts - pushing Maternal tachycardia/accelerations with contractions Delayed return of the fetal heart rate from a deceleration Descent of the fetus in the birth canal Rotation of the fetus in the birth canal In some cases during the second stage of labor, a good and reliable ultrasound FHR signal may not be obtainable, and the use of a fetal scalp electrode must be considered (fetal ECG). Fetal decelerations, Fetal tachycardia Heart Rate Sound The heart rate sound emitted by the device is a representation of movement that, in most cases, permits accurate auscultation of the FHR corresponding to the FHR displayed on the monitor and rate pattern depicted on the trace recording. On occasion, the user may hear an FHR that differs from the FHR display and the recorded trace. This may occur in situations where the fetal heart moves partly out of the transducer ultrasound beam. In these cases, the user may hear the FHR emitted from the monitors speaker, even though another periodic signal (usually the maternal heart rate) has become stronger. The autocorrelation algorithm will display the stronger maternal heart rate, despite the persistence of a weaker fetal signal. These occurrences are usually very brief and, if persistent, can be addressed by repositioning the transducer. 176 12 Monitoring FHR and FMP Using Ultrasound Signal Quality Indicator The signal quality on the Avalon fetal monitor is indicated by a triangle on the touchscreen that is displayed in one of three ways:
1 Completely filled triangle, indicating good signal quality (good/full). 2 Half-filled triangle, indicating limited signal quality. This condition may indicate a weak or ambiguous signal. If this status persists, reposition the transducer (acceptable/medium). 3 Empty triangle, indicating insufficient signal quality. No FHR is displayed on the monitors numeric display or the recorded trace. If this status persists, reposition the transducer (poor/no signal). Examples of Artifacts When monitoring the maternal ECG, a beat-to-beat maternal heart rate trace is printed alongside the FHR recorded trace. When monitoring the maternal SpO2 derived pulse rate, a filtered and averaged heart rate trace is printed. Following are recorded trace examples of complaints received regarding inaccurate output from the Avalon monitors. Scaling is 3 cm/min and 30 bpm/cm. Double-Counting Baseline Rate Baseline Variability Accelerations Decelerations 120 Moderate Present Not apparent 177 12 Monitoring FHR and FMP Using Ultrasound Double-Counting Contractions Artifact Comment Remediation Half-Counting Excessive, coupling, hypertonus Double-Counting Reassuring tracing. The excessive uterine activity should prompt discontinuation of any oxytocic agent. The true fetal rate can be confirmed by auscultation or by fetal scalp electrode. Baseline Rate Baseline Variability Accelerations Decelerations Contractions Artifact Comment Remediation 120 Moderate Present Not apparent Minimal Half-counting, noise, drop out Reassuring tracing. The half-count at 4-5 minutes into the tracing may simulate a fetal deceleration, but the abruptness and the lack of any compensatory changes when the normal rate returns suggests that this is half-counting. Insertion of the maternal heart rate
(see below) may produce a similar pattern. Note also very brief episodes of half-counting, maternal insertion, and signal dropout. Auscultation or the application of a direct scalp electrode, if feasible, will reveal the true fetal heart rate. 178 12 Monitoring FHR and FMP Using Ultrasound Maternal-Switching (Maternal Insertion) Baseline Rate Baseline Variability Accelerations Decelerations Contractions Artifact Comment Remediation 170 - Tachycardia Moderate Unable to determine Absent Absent Maternal insertion, noise The fetus has an elevated baseline rate of about 170 bpm with minimal to moderate variability. The ability to assess fetal status is limited because about half of the tracing displays the maternal heart rate. The application of a maternal transducer (ECG or pulse oximeter) will likely resolve any possible confusion with the tracing. Repositioning the transducer may produce a more reliable tracing. Consideration must also be given to applying a fetal scalp electrode. Noisy/Erratic Signal and Dropout Baseline Rate Baseline Variability Accelerations Decelerations Contractions Artifact 140 Moderate Present Absent Minimal Noisy signal, drop-out 179 12 Monitoring FHR and FMP Using Ultrasound Noisy/Erratic Signal and Dropout Comment Remediation Reassuring tracing. Note that there is episodic drop out of the signal with discontinuity of the fetal tracing. Either improving the position of the transducer or the application of a fetal scalp electrode will reduce the amount of artifact in the tracing.

The Avalon CL Transducer system provides the option to monitor twins with cableless transducers. The Avalon CTS system and the CL F&M Pod do not have this option. FM30/50 Twin FHRs are monitored throughout labor and delivery. After rupture of the membranes, you can monitor one twin externally using ultrasound, and the other internally using DECG. Refer to the appropriate preceding chapters for contraindications, and more information about the available measurement methods. FHR detection by the monitor does not always indicate that the fetuses are alive. Confirm fetal life before monitoring, and continue to confirm that the fetuses are the signal source for the recorded fetal heart rates. See Confirm Fetal Life Before Using the Monitor on page 10 and Cross-Channel Verification (CCV) on page 159. Important Considerations When monitoring:
Ensure that you are recording two different fetal heart rates. The cross-channel verification feature alerts you if the two heart rates coincide (if both transducers are recording the same FHR). If this happens, check the trace and if necessary, reposition an ultrasound transducer to detect the second FHR correctly. Fetal heart rate measurements are labeled in the order in which you plug in the transducers for those measurements. It does not matter which fetal sensor socket you use, as the monitor allocates a channel automatically. For instance, the first transducer you connect is automatically allocated a channel, and the measurement is labeled FHR1, the second is labeled FHR2, and so on. If you need to disconnect the transducers measuring the FHR temporarily, with the intention to continue monitoring after the temporary break (for example, if the mother needs to go to the bathroom), it is important that you reconnect the transducers in the same order as you originally connected them to make sure that the measurement labels remain consistent. Upon discharge of the patient all connected transducers are reset from left to right. Example: Only one transducer is still connected to the monitor, it was labeled FHR2 while monitoring the previous discharged patient; it is now reset to FHR1. The transducer finder LED lets you identify at a glance which transducer is monitoring which heart rate channel. 183 13 Monitoring Twin FHRs The fetal sensor socket to which a transducer is connected is identified by the transducer position indicator in the setup menu header:
FM20/FM30 FM40/FM50 The trace recorded for FHR1 is thicker (darker) than that recorded for FHR2. This ensures that the two heart rates are easily distinguishable. The thickness of the recorded trace can be changed in Configuration Mode. Remember that only one fetal heartbeat can be heard from the loudspeaker at a time. The audio source symbol shows you which fetus you are listening to. To hear the other fetal heartbeat, select the fetal heart rate sound for this channel (see Selecting Fetal Heart Sound on page 169). Monitor maternal pulse, especially during later stages of labor, to avoid mistaking maternal heart rate for FHR. Make sure that you are recording the best possible signals by referring to the signal quality indicators and repositioning the transducers if necessary. For the Avalon CL transducer system, see Cableless Monitoring - Important Considerations on page 167. Monitoring Twins Externally To monitor twin FHRs externally, you need two ultrasound transducers. Follow the procedures described in Monitoring FHR and FMP Using Ultrasound on page 165. The transducer finder LED lets you identify at a glance which transducer is monitoring which FHR channel, and lights when you select the FHR numeric field on the screen. 184 Example of the screen showing ultrasound monitoring of twin FHRs:
13 Monitoring Twin FHRs FHR 1 1 2 Toco parameter 3 FHR 2 Monitoring Twins Internally FM30/50 Monitor one twin using the procedures described in Monitoring FHR and FMP Using Ultrasound on page 165. Monitor the second twin using the procedures described in Monitoring FHR Using DECG on page 199. Example of a screen showing twin monitoring using a combination of US and DECG (the fetal heart rate monitored via DECG is labeled "dFHR1"/"dFHR2"/"dFHR3" on the screen):
dFHR 1 1 2 Toco parameter 3 FHR 2 Separating FHR Traces To help you to interpret traces with similar baselines, you can separate the baselines by an offset of 20 bpm by switching on trace separation. For details of the offset, see Separation Order Type on page 186. 185 13 Monitoring Twin FHRs Switching Trace Separation On and Off Connect transducers to the monitor to measure FHR. Depending on the measurement method, you need either two ultrasound transducers or, for FM30/FM50, one ultrasound and one Toco+ transducer, or one CL ECG/IUP transducer (to monitor DECG):
1 Enter the Main Setup menu by pressing the Main Setup. 2 3 4 Exit the Main Setup menu. Select Fetal Recorder. Select Trace Separation to switch between On and Off. Separation Order Type In Configuration Mode, you can choose between two methods, Standard and Classic, for dealing with the trace offsets on the recording (the order in which they are separated) when Trace Separation is On. Standard: the FHR2 trace is shifted up by 20 bpm (it is recorded 20 bpm higher than it really is). No offset is ever applied to the FHR1 trace - it stays where it is (a third FHR would be shifted down by 20 bpm). Classic: the FHR1 trace is shifted up by 20 bpm when there is more than one FHR measurement. No offset is ever applied to the FHR2 trace - it stays where it is (a third FHR would be shifted down by 20 bpm). When Trace Separation is On When trace separation is turned on, the recorder prints a dotted line labeled with the two FHRs at the top, and +20 at the bottom. Examples of the two methods (Standard, Classic) for determining the trace separation order are provided here.
"Standard" Separation Order To make differentiating the traces easier, the trace from the ultrasound transducer connected to the FHR2 channel is separated from that of FHR1 by 20 bpm. In other words, the trace for FHR2 is recorded 20 bpm higher than it really is. The trace for FHR1 is never shifted. The recorder prints a dotted line labeled +20 across the FHR scale, to identify the trace for FHR2. The FHR trace is labeled +20 every 5 cm:
The label for FHR2 is annotated with a black filled +20:
186 The following trace shows trace separation switched on. 13 Monitoring Twin FHRs Only the FHR2 trace is offset. The numerical FHR value displayed on the monitor remains unchanged. Subtract 20 from the recorded trace for FHR2 to obtain the true FHR2 value. For example, if the recorded trace shows 160, then the true FHR is 140.
"Classic" Separation Order To make differentiating the traces easier, the trace for FHR1 is offset by +20 bpm when FHR2 is present. The FHR2 trace is never shifted. The recorder prints a dotted line labeled+20 across the FHR scale, to identify the trace for FHR1. The FHR trace is labeled +20 every 5 cm:
The label for FHR1 is annotated with a black filled +20:
The following trace shows trace separation switched on. Only the FHR1 trace is shifted. The numerical FHR value displayed on the monitor remains unchanged. Subtract 20 from the recorded trace for FHR1 to obtain the true FHR1 value. For example, if the recorded trace shows 160, then the true FHR is 140. 187 13 Monitoring Twin FHRs When Trace Separation is Off To indicate that trace separation is switched off, a dotted line labeled +0 prints across the FHR scale. 1 Standard trace separation switched off here 2 Classic trace separation switched off here 188 13 Monitoring Twin FHRs Troubleshooting Common problems that may occur when monitoring FHR using ultrasound are listed in Monitoring FHR and FMP Using Ultrasound on page 165. See also Monitoring FHR Using DECG on page 199 for common problems you might encounter when monitoring FHR directly. The following problem may occur when monitoring twins. Problem The question mark is printed repeatedly, and appears on the screen and the INOP Coincidence is issued. Possible Cause Both transducers are recording the same FHR, or one fetal transducer is recording the maternal HR. Solution Reposition an ultrasound transducer. See Recommended Actions for Coincidence INOP on page 164. For more information, see Additional Information on page 173. 189 13 Monitoring Twin FHRs 190 14 14Monitoring Triple FHRs If your monitor is equipped with the triplets option, it carries the label:
You can monitor triple FHRs externally using three ultrasound transducers. With the Avalon CL Transducer system, you can monitor triplets with cableless transducers. The Avalon CTS system and the CL F&M Pod do not have this option. Refer to the appropriate preceding chapters for contraindications, and more information about the available measurement methods. FHR detection by the monitor may not always indicate that the fetuses are alive. Confirm fetal life before monitoring, and continue to confirm that the fetuses are the signal source for the recorded fetal heart rates. See Confirm Fetal Life Before Using the Monitor on page 10 and Cross-Channel Verification (CCV) on page 159. Important Considerations The procedures and any contraindications that apply for twins monitoring also apply for monitoring triplets. In addition, when monitoring triplets: Be aware that monitoring three FHRs is inherently more difficult than monitoring single or twin FHRs. The nature of the application increases the likelihood that a fetal heart rate is monitored by more than one transducer. Ensure that you are recording three different fetal heart rates. Pay particular attention to any coincidence of heart rates detected by the monitor's cross-channel verification feature. Fetal heart rate measurements are labeled in the order in which you plug in the transducers for those measurements. It does not matter which fetal sensor socket you use, as the monitor allocates a channel automatically. For instance, the first transducer you connect is automatically allocated a channel, and the measurement is labeled FHR1, the second is labeled FHR2, and the third FHR3. If you need to disconnect the transducers measuring the FHR temporarily, with the intention to continue monitoring after the temporary break (for example, if the mother needs to go to the bathroom), it is important that you reconnect the transducers in the same order as you originally connected them to make sure that the measurement labels remain consistent. Upon discharge of the patient all connected transducers are reset from left to right. Example: Only one transducer is still connected to the monitor, it was labeled FHR2 while monitoring the previous discharged patient; it is now reset to FHR1. 191 14 Monitoring Triple FHRs The transducer finder LED lets you identify at a glance which transducer is monitoring which heart rate channel. The fetal sensor socket to which a transducer is connected, is identified by the transducer position indicator in the setup menu header:
FM20/FM30 FM40/FM50 The trace recorded for the FHR3 is thicker (darker) than that recorded for FHR1, which is thicker than that for FHR2. This ensures that the three heart rates are easily distinguishable. The thickness of the recorded trace can be changed in Configuration Mode. Remember that only one fetal heartbeat can be heard from the loudspeaker at a time. The audio source symbol shows you which fetus you are listening to. To hear the other fetal heartbeat, select the fetal heart rate sound for this channel (see Selecting Fetal Heart Sound on page 169). Monitor maternal pulse to avoid mistaking maternal heart rate for FHR. Ensure you are recording the best possible signals by referring to the signal quality indicators and repositioning the transducers if necessary. For the Avalon CL transducer system, see Cableless Monitoring - Important Considerations on page 167. Monitoring Triplets To monitor triple FHRs, you need three ultrasound transducers. Follow the procedures described in Monitoring FHR and FMP Using Ultrasound on page 165 and in Monitoring Twin FHRs on page 183. The transducer finder LED lets you identify at a glance which transducer is monitoring which heart rate channel. Separating FHR Traces To help you to interpret traces with similar baselines, you can separate the baselines by an offset of 20 bpm by switching on trace separation. For details of the offset, see Separation Order Type on page 186. 192
"Standard" Separation Order 14 Monitoring Triple FHRs To make differentiating the traces easier, the trace for FHR2 is offset by +20 bpm, and the trace for FHR3 is offset by -20 bpm. In other words, the trace for FHR2 is recorded 20 bpm higher than it really is, while the trace for FHR3 is recorded 20 bpm lower than it really is. The trace for FHR1 is never shifted. The recorder prints a dotted line labeled +20 across the FHR scale, to identify the trace for FHR2. The recorder prints a dotted line labeled -20 across the FHR scale, to identify the trace for FHR3. The FHR trace is labeled every 5 cm. The label for FHR2 is annotated with +20 and the FHR3 label is annotated with
-20. The following trace shows triplets with Trace Separation on, and using Standard separation order. The traces for FHR2 and FHR3 are offset. The numerical FHR values displayed on the monitor remain unchanged. Subtract 20 from the recorded trace for FHR2 to obtain the true FHR2. For example, if the recorded trace shows 160 bpm, then the true FHR is 140 bpm. Similarly, add 20 to the recorded trace for FHR3 to obtain the true FHR3. 193 14 Monitoring Triple FHRs
"Classic" Separation Order To make differentiating the traces easier, the trace for FHR1 is offset by +20 bpm when other FHR measurements are present, and the trace for FHR3 is offset by -20 bpm. The FHR2 trace is never shifted. In other words, the FHR traces are always sorted in ascending order from top to bottom. The recorder prints a dotted line labeled +20 across the FHR scale, to identify the trace for FHR1. The recorder prints a dotted line labeled -20 across the FHR scale, to identify the trace for FHR3. The FHR trace is labeled every 5 cm. The label for FHR1 is annotated with +20 and the FHR3 label is annotated with
-20. The following trace shows triplets with Trace Separation on, and using Classic separation order. The traces for FHR1 and FHR3 are shifted. The numerical FHR values displayed on the monitor remain unchanged. Subtract 20 from the recorded trace for FHR1 to obtain the true FHR1. For example, if the recorded trace shows 160 bpm, then the true FHR is 140 bpm. Similarly, add 20 to the recorded trace for FHR3 to obtain the true FHR3. 194 14 Monitoring Triple FHRs Switching Trace Separation On and Off 1 Connect three ultrasound transducers to the monitor to measure FHR. 2 See Switching Trace Separation On and Off on page 186 for details of how to switch trace separation on or off. When Trace Separation is On When trace separation is turned on, the recorder prints a dotted line labeled with the three FHRs at the top, and 20 at the bottom. Examples of the two methods (Standard, Classic) for determining the trace separation order are provided here. When Trace Separation is Off To indicate that trace separation is switched off, a dotted line labeled +0 prints across the FHR scale. 1 Standard trace separation switched off here 195 14 Monitoring Triple FHRs 2 Classic trace separation switched off here Troubleshooting Common problems that may occur when monitoring FHR using ultrasound are listed in Monitoring FHR and FMP Using Ultrasound on page 165. The following problem may occur when monitoring triplets. Problem The question mark is printed repeatedly, and appears on the screen and the INOP Coincidence is issued. Possible Cause More than one transducer is recording the same FHR, or a fetal transducer records the same heart rate as the maternal HR. Solution Reposition one or more ultrasound transducer, as appropriate. See Recommended Actions for Coincidence INOP on page 164 For more information, see Additional Information on page 173. 196 15 15Fetal Heart Rate Alarms Fetal heart rate (FHR) alarms can give both audible and visual warning of a non-reassuring fetal condition. Your monitor must be configured to alarm mode All to enable the FHR alarms (see Alarms on page 117). Changing Alarm Settings Turning FHR alarms on or off When you do any of the following actions for any FHR measurement channel, this applies for all active FHR measurements, ultrasound, DECG, and aFHR:
Changing alarm limits Changing alarm delays Changing signal loss delay The monitor retains these settings, even when switched off. The alarm limits are printed on the trace every few pages if alarms are on. Turning Alarms On or Off 1 Connect either an ultrasound or a DECG transducer to a free socket on the monitor, or use the CL F&M Pod. 2 Enter the setup menu for a connected FHR measurement. 3 Select Alarms to switch between On and Off. Changing Alarm Limits 1 Connect either an ultrasound or a DECG transducer to a free socket on the monitor, or use the CL F&M Pod. 2 Enter the setup menu for a connected FHR measurement. 3 To change the high alarm limit, select High Limit and select the alarm limit from the pop-up list. 4 To change the low alarm limit, select Low Limit and select the alarm limit from the pop-up list. 197 15 Fetal Heart Rate Alarms Changing Alarm Delays You can change the alarm delays if the Alarm Mode is set to All. 1 Connect either an ultrasound or a DECG transducer to a free socket on the monitor, or use the CL F&M Pod. 2 Enter the setup menu for a connected FHR measurement. 3 To change the high alarm limit delay time, select High Delay and select the delay time (in seconds) from the pop-up list. 4 To change the low alarm limit delay time in seconds, select Low Delay and select the delay time (in seconds) from the pop-up list. Changing Signal Loss Delay The signal loss delay is the configurable delay before a Signal Loss INOP is issued. You can change the delay:
1 Connect either an ultrasound or a DECG transducer to a free socket on the monitor, or use the CL F&M Pod. 2 Enter the setup menu for a connected FHR measurement. 3 Select SignalLoss Delay and select the signal loss INOP delay time (in seconds) from the pop-up list. 198 16 16Monitoring FHR Using DECG FM30/50 This chapter describes how to monitor a single fetal heart rate via direct ECG (DECG), using a spiral fetal scalp electrode in the intrapartum period. Read and adhere to the instructions that accompany the fetal scalp electrode, the DECG adapter cable, and the attachment electrode. Pay attention to all the contraindications, warnings, and for the DECG adapter cable, the cleaning and disinfection procedures. Before starting to monitor, first define the fetal position, and ensure that it is suitable for DECG monitoring. Misidentification of Maternal HR as FHR Confirm fetal life before monitoring, and continue to confirm that the fetus is the signal source for the FHR during monitoring. Here are two examples where the maternal HR can be misidentified as the FHR when using a fetal scalp electrode:
Electrical impulses from the maternal heart can sometimes be transmitted to the fetal monitor through a recently deceased fetus via the spiral scalp electrode, appearing to be a fetal signal source. The recorded maternal HR, and any artifact, can be misinterpreted as an FHR especially when it is over 100 bpm. To reduce the possibility of mistaking the maternal HR for FHR, monitor both maternal and fetal heart rates (see Monitoring Maternal Heart / Pulse Rate on page 221). The monitor's cross-channel verification (CCV) facility can help by automatically detecting when the same heart rate is being recorded by different transducers. See Confirm Fetal Life Before Using the Monitor on page 10 and Cross-Channel Verification (CCV) on page 159. If the Coincidence INOP is issued at the fetal monitor if you are measuring FHR with DECG:
1 Confirm that the scalp electrode is placed correctly. 2 Confirm fetal life by palpation of fetal movement or auscultation of fetal heart sounds using a fetoscope, stethoscope, or Pinard stethoscope. If you cannot hear the fetal heart sounds, and you cannot confirm fetal movement by palpation, confirm fetal life using obstetric ultrasonography. 3 199 16 Monitoring FHR Using DECG 4 In case of difficulties deriving a stable maternal pulse reading using the Toco MP or CL Toco+ MP transducer, use SpO2 instead. In case of similar problems with the pulse measurement from SpO2, use MECG instead. Reasons to switch the method for deriving a maternal pulse or heart rate include: motion artifacts, arrhythmia, and individual differences in pulse signal quality on the abdominal skin (via Toco+ MP). What You Need You can measure fetal DECG using the equipment combinations shown in the following figures. WARNING Never attempt to connect the fetal scalp electrode to anything other than the correct DECG adapter cable. DECG with Toco+

Prepare for DECG monitoring using the list below. The standard procedures in use in your facility determine the sequence of actions. 1 2 Depending on the equipment you are using, ensure that the Toco+ transducer, CL Toco+ MP, the If you change the monitoring mode from US to DECG, first disconnect the US transducer. CL ECG/IUP transducer, or the patient module is connected to the fetal monitor. 3 Attach the fetal scalp electrode to the fetus, following the instructions supplied with the fetal scalp electrode. 5 4 Attach a pre-gelled attachment electrode to the DECG adapter cable, following the instructions supplied with the DECG adapter cable. Fix the attachment electrode to the mother's thigh, following the instructions supplied with the attachment electrode. Depending on the equipment you are using, connect the red connector plug on the DECG adapter cable to the red connector on the Toco+ transducer, CL Toco+ MP, the CL ECG/IUP transducer, or the patient module. 6 Connect the fetal scalp electrode to the DECG adapter cable. You are now ready to begin monitoring DECG. WARNING The fetal/maternal monitor is not a diagnostic ECG device. In particular, the display of fetal/maternal ECG is intended only for evaluating signal quality for fetal/maternal heart rate as derived from the ECG waveform. When in doubt, it can be used to identify sources of compromised signal quality, such as noise or muscle artifacts. It can subsequently be used to verify the result of measures taken to resolve them (e.g. checking ECG cable connections or adapting the fetal ArtifactSuppress configuration). The safety and effectiveness of the displayed fetal/maternal ECG waveform (i.e. P, QRS, and T segments) for evaluation of fetal/maternal cardiac status during labor have not been evaluated. Monitoring DECG To simultaneously measure DECG and MECG, you need the CL ECG/IUP transducer or the patient module for DECG, and a Toco+, CL Toco+ MP, or CL ECG/IUP transducer for MECG (see Monitoring Maternal Heart / Pulse Rate on page 221). Alternatively, you can monitor the maternal pulse rate via pulse oximetry (see Pulse Rate from SpO2 on page 228). You can also monitor maternal pulse with the Toco MP or CL Toco+ MP transducer. In any case where you would use a Toco+ or Toco MP transducer, you can also monitor with a CL Toco+ MP transducer. 1 Switch on the recorder. 202 16 Monitoring FHR Using DECG 2 The heart rate monitored via DECG is labeled dFHR1 / dFHR2 / dFHR3 on the screen. If configured, the DECG wave is displayed automatically on the screen, labeled DECG, and fetal. If MECG is being monitored, both waves are displayed, with the DECG wave above the MECG wave. The MECG wave is labeled MECG and maternal. 3 Check the artifact suppression setting and change it if necessary (see Suppressing Artifacts on page 204). 1 Measurement label (dFHR1) 2 Measurement label (Toco) 3 Measurement label (FHR2) 4 Measurement label (HR) 5 6 MECG wave with maternal label 7 DECG wave with fetal label 8 Measurement label (Temp) maternal temperature 9 Measurement label NBP 1mV scale bar NOTE The 1mV scale bar for the DECG and MECG wave is not displayed on the screen if you monitor DECG or MECG with an Avalon CTS system. The Avalon CTS system does not provide a scaled ECG. 203 16 Monitoring FHR Using DECG WARNING Periodically compare the mother's pulse with the signal coming from the monitor's loudspeaker to ensure that you are monitoring fetal heart rate. If the maternal HR coincides with the FHR, do not misinterpret the maternal HR as the FHR (see also Confirm Fetal Life Before Using the Monitor on page 10 and Cross-Channel Verification (CCV) on page 159. Suppressing Artifacts When the monitor's artifact suppression is on, instantaneous heart rate changes of 28 bpm or more, however caused, are not recorded. Fetal arrhythmia will also be suppressed. If you suspect fetal arrhythmia, switch artifact suppression off. When artifact suppression is off, all recorded fetal heartbeats within the specified range are shown. The default setting is On (artifacts are suppressed). To change the setting:
1 Enter the Setup dFHR1 menu. 2 Select ArtifactSuppress to switch between artifact suppression On (artifacts are suppressed) and Off
(no artifact suppression, use this setting if you suspect fetal arrhythmia). When artifact suppression is off, Artifact Suppression Off is annotated on the trace recording. Printing the Waveform You can print the DECG wave onto the trace paper. Refer to Printing the ECG Waveform on page 231. 204 16 Monitoring FHR Using DECG Troubleshooting NOTE In many cases you need to see the DECG wave to check if the signal quality is good enough to derive a valid fetal heart rate. In the dFHR setup menu, switch on the display of the DECG wave.

Testing DECG Mode See the monitor's Service Guide. 205 16 Monitoring FHR Using DECG 206 17 17Monitoring Uterine Activity Externally You can measure uterine activity externally using a Toco transducer. You can also use a Toco+, Toco MP, or a CL Toco+ MP transducer for the same purpose, although they also have more (ECG/
IUP and Pulse) capabilities. The external Toco transducer allows to monitor the frequency, duration, and relative strength of contractions, but not their absolute intensity. Amplitude and sensitivity depend on various factors such as the position of the transducer, the belt tension, and the size of the patient. What You Need Toco, Toco MP, or Toco+ transducer CL Toco+ MP transducers (additionally capable of providing the maternal pulse measurement) 207 17 Monitoring Uterine Activity Externally Abdominal Belt (disposable shown) External Toco Monitoring Fasten the abdominal transducer belt around the patient. Prepare for Toco monitoring using the list below. The standard procedures in use in your facility determine the sequence of actions. 1 2 Connect the Toco transducer to a free socket on the monitor. The Toco baseline is automatically reset. The Toco display shows 20. "Toco", indicating external uterine measurement, is printed on the trace at intervals. 3 Place the transducer on the patient's fundus to ensure the optimum recording of uterine activity. 4 Reset the Toco baseline as necessary (see Resetting the Toco Baseline on page 208), but not during a contraction. The following example trace shows two contractions. Resetting the Toco Baseline 1 2 Press the Toco Baseline SmartKey. This resets the Toco baseline to 20 on the display and trace. If the Toco value is negative for more that five seconds, the Toco baseline is automatically reset to 0 units. Toco Sensitivity If the Toco sensitivity is too high, and the Toco trace exceeds the paper scale, you can reduce the Toco sensitivity to 50%. The default setting is 100%. To change the Toco sensitivity:
1 Enter the Setup Toco menu. 2 Select Gain to switch between 100% and 50%. Troubleshooting 208 External Toco Monitoring Problem Quality of the trace deteriorates or the Toco baseline varies Possible Causes The belt is incorrectly fastened and is too slack or too tight, or the belt has lost its elasticity.

If the second transducer passes the tests, confirming that the first transducer is defective, contact your service personnel. If the second transducer also fails the tests, contact your service personnel. To test a Toco transducer:
1 Switch on the monitor and the recorder. 2 Connect the transducer to the fetal monitor. 3 Gently apply pressure to the pick-
up button. 4 Check if after a few seconds the values on the display and paper show this change in pressure. You can test all Toco transducers, including the cableless ones, as described above. 210 18 18Monitoring Uterine Activity Internally FM30/50 You can monitor intrauterine pressure (IUP) using an intrauterine catheter together with a patient module, Toco+, or the CL ECG/IUP or CL Toco+ MP transducer, after rupture of the membranes and the cervix is sufficiently dilated. What You Need IUP with Patient Module The figure below shows the complete connection chain from the IUP catheter to the fetal monitor using the patient module:

The CL F&M Pod is used together with a single-use electrode patch. The electrode patch has five adhesive electrodes. The CL F&M Pod and electrode patch are placed on the maternal abdomen. It picks up the fetal and maternal electrocardiography (ECG) signals, and the uterine electromyography (EMG) signals. The CL F&M Pod separates and processes the signals, and transmits aFHR, aHR, and aToco to the fetal monitor via the CL base station. CAUTION Use the CL F&M Pod and electrode patch with singleton pregnancies only. The measurements have been validated with a gestational age of >36 weeks. NOTE Fetal ECG and uterine EMG signals are very small. Therefore, skin preparation is required when applying the electrodes. Different measurements for the same physiological parameter may have a different appearance on the trace, due to variability (HR), averaging, delay, amplitude, or artifacts. The beat-to-beat variability of aFHR may appear lower than FHR from ultrasound and lower than dFHR from DECG due to averaging. The accuracy of all FHR parameters is sufficient for diagnosis following commonly agreed guidelines. Fetal Heart Rate aFHR It is recommended to verify the presence of the fetal heart beat, for example with a stethoscope, before starting continuous monitoring with the CL F&M Pod. 215 19 Monitoring aFHR, aHR, and aToco CAUTION If the aFHR signal quality indicator on the fetal monitor screen continuously indicates an insufficient signal quality (empty triangle), although the CL F&M electrode status is green, then an alternative method to monitor should be used. Uterine Activity aToco The CL F&M Pod measures the electrical activity of the uterus which is different to the mechanical measurements of a Toco transducer or an IUP catheter. Depending on the measurement method, the shape of a recorded contraction can look different. The uterine EMG signals can be interfered with by the electrical activity of other muscles, for example during maternal or fetal movements or position changes. CAUTION The aToco measurement does not represent the absolute intrauterine pressure. If aToco seems questionable, verify uterine activity by other means (maternal perception, manual palpation, or intrauterine pressure (IUP) measurement). For monitoring the real intrauterine pressure in mmHg or kPa, an IUP catheter is required. CAUTION The duration of the contraction measured by the CL F&M Pod can be shorter than the physical contractions. When you palpate the uterus, there is a delay between the manual detection of contraction, and when it is displayed at the monitor. CAUTION Maternal or fetal movements can cause electrical signals that may result in intrauterine contraction-like artifacts. Maternal movement When consistent maternal movement is detected:
A question mark is displayed in front of the aToco numeric at the monitor (?aToco). The aToco trace is printed with a lighter intensity for the duration of the maternal movements, indicating that the signal may be compromised and not suitable for trace interpretation. Uterine Activity Measurement Priority When several uterine activity measurements are active, the priority given on the monitor display is:
IUP (Intrauterine pressure from the connection with an IUP catheter) aToco (CL F&M Pod) Toco (CL Toco+MP transducer, Toco+ or Toco MP wired transducer) 216 19 Monitoring aFHR, aHR, and aToco aToco Sensitivity Monitoring with the CL F&M Pod, the aToco sensitivity can be set to High or Low at any time. The Low sensitivity setting provides an additional suppression of artifacts, for example artifacts coming from maternal and fetal movements. The additional filtering delays the onset of recording the contraction on the trace and shows a reduced amplitude. The default setting is High and recommended for active labor. Setting the aToco Sensitivity 1 2 Select the Setup aToco menu. Select the Sensitivity by toggling between High and Low. What You Need For monitoring with the CL F&M Pod, see Avalon CL Fetal & Maternal Pod on page 21 and CL Fetal & Maternal Electrode Patch on page 91. For assigning the CL F&M Pod, see CL Pod Assignment on page 99. For applying the electrode patch and the CL F&M Pod, see Applying the CL Fetal & Maternal Patch and Pod on page 100. At the Monitor Switch on the recorder. 1 2 The fetal heart rate is labeled aFHR1, aFHR2, or aFHR3 on the screen. The CL F&M Pod monitors only singletons, but if in addition to aFHR a CL US transducer and/or a scalp electrode (DECG) are used to monitor FHR, the aFHR numeric is labeled 1 to 3 depending on the sequence in which the other measurement methods are added. aFHR and aHR have a QRS tone.

Patient in unfavorable position Make the patient more comfortable, if the abdominal muscles are relaxed it may improve the signal. For example, place a pillow to support the patients back. If the signal indication does not improve, consider monitoring with alternative methods. If the abdomen is mobile, or patient position has changed, use a rolled blanket/towel or pillow to support abdomen to keep the patch centered on the uterus. If the signal indication does not improve, consider monitoring with alternative methods. Verify the FHR by independent means. Mobile abdomen aFHR not recorded or questionable aFHR is less than 60 bpm or over 240 bpm, fetal demise, fetal arrhythmia, or the baby is born NOTE For all signal loss, malfunction, or other alerts see Patient Alarms and INOPs on page 129. 219 19 Monitoring aFHR, aHR, and aToco 220 20 20Monitoring Maternal Heart /
Pulse Rate You can monitor the maternal heart/pulse rate using one of five sources:
Maternal heart rate (HR) via MECG electrodes Maternal heart rate (aHR) via CL F&M Pod Maternal pulse rate from Toco MP or CL Toco+ MP transducer (Pulse) Maternal pulse rate from SpO2 (Pulse) Maternal pulse rate from NBP (Pulse) Maternal heart/pulse rates derived from Toco MP or CL Toco+ MP, SpO2, aHR, and MECG are continuous measurements, and are compared against the FHR for cross-channel verification. Average pulse rate derived from noninvasive blood pressure is an intermittent measurement, and is therefore not used for cross-channel verification.

For measuring DECG, you need a CL ECG/IUP transducer or a patient module (see also Monitoring FHR Using DECG on page 199). 223 20 Monitoring Maternal Heart / Pulse Rate Applying Electrodes To derive the maternal HR (when you do not want to view the MECG waveform), you can place the electrodes just below the outer end of the clavicle near each shoulder. 1 MECG Electrodes Making Connections WARNING Follow the instructions supplied with each of the monitoring accessories you are using. Prepare for monitoring maternal HR using the list below. The standard procedures in use in your facility determine the sequence of actions. 1 Depending on the equipment you are using, ensure that either the Patient Module or the Toco+
transducer is connected to the fetal monitor. If you are using cableless monitoring, use the CL ECG/IUP or the CL Toco+ MP transducer. 2 Connect a pre-gelled foam electrode to each of the two leads on the MECG adapter cable. 3 Apply the foam electrodes to the patient, following the instructions supplied with the foam electrodes. 4 Depending on the equipment you are using, connect the pink connector plug on the MECG adapter cable to the pink connector on either the Patient Module or the Toco+ transducer. If you are using cableless monitoring, connect the MECG Adapter cable to the connectors of the CL ECG/
IUP or the CL Toco+ MP transducer. You are now ready to monitor maternal HR. Monitoring Maternal HR Switch on the recorder. 1 2 The maternal heart rate is labeled HR on the screen. 224 Monitoring MECG Wave 20 Monitoring Maternal Heart / Pulse Rate WARNING The fetal/maternal monitor is not a diagnostic ECG device. In particular, the display of fetal/maternal ECG is intended only for evaluating signal quality for fetal/maternal heart rate as derived from the ECG waveform. When in doubt, it can be used to identify sources of compromised signal quality, such as noise or muscle artifacts. It can subsequently be used to verify the result of measures taken to resolve them
(e.g., checking ECG cable connections or adapting the fetal ArtifactSuppress configuration). The safety and effectiveness of the displayed fetal/maternal ECG waveform (i.e., P, QRS, and T segments) for evaluation of fetal/maternal cardiac status during labor have not been evaluated. FM30/50 When measuring MECG with the Avalon FM30 or FM50, the MECG waveform, along with the heart rate numeric, is displayed on the screen when using a Toco+, CL Toco+ MP transducer, a patient module, or a CL ECG/IUP transducer. If a maternal ECG wave analysis is required, use a patient monitor. WARNING The fetal/maternal monitor is NOT intended for use during defibrillation, electro-surgery, or MRI. Remove all transducers, sensors, and accessories before performing electro-surgery, defibrillation, or MRI, otherwise harm to the patient or the user can result. Applying Electrodes To obtain a satisfactory maternal ECG waveform, you must use the RA to LL (lead II) position of the standard 5-lead ECG. 1 2 Place the RA electrode
(A) directly below the clavicle and near the right shoulder. Place the LL electrode
(B) on the left lower abdomen. 225 20 Monitoring Maternal Heart / Pulse Rate Viewing the Waveform on the Screen 1 Measurement label dFHR1 2 Measurement label Toco 3 Measurement label FHR2 4 Measurement label HR 5 6 MECG wave with maternal label 7 DECG wave with fetal label 8 Measurement label Temp maternal temperature 9 Measurement label NBP 1mV scale bar NOTE The 1mV scale bar for the DECG and MECG wave is not displayed on the screen if you monitor DECG or MECG with an Avalon CTS system.

See Recommended Actions for Coincidence INOP on page 164 See Patient Alarms and INOPs on page 129 You can print the MECG wave onto the trace paper. Refer to Printing the ECG Waveform on page 231. Pulse Rate from Toco MP The maternal pulse is taken from the Toco MP or CL Toco+ MP transducer when SpO2 or MECG measurements are not used or have signal loss. When the pulse rate is very low, or strong arrhythmia is present, the pulse rate measured by the Toco MP or CL Toco+ MP transducer may differ from the heart rate calculated from MECG. If the mother is moving about, or began pressing during the second stage of labor, this can cause longer gaps in the recording of the maternal pulse signal. In this case, use the SpO2 or MECG measurement to derive the maternal heart rate. WARNING No alarm is possible when Toco MP or CL Toco+ MP transducer is the source of the pulse rate. No QRS tone is audible when Toco MP or CL Toco+ MP transducer is the source of the pulse rate. The Toco MP or CL Toco+ MP transducer signal is significantly less reliable, if the patient is up and moving about, or is pushing during the second stage of labor. NOTE In rare cases, it is possible to pick up a fetal signal source. When a Toco MP or CL Toco+ MP transducer is connected to the monitor, but not applied to the patient, the measurement may generate unexpected intermittent pulse readings. 227 20 Monitoring Maternal Heart / Pulse Rate Pulse Rate from SpO2 If you are not monitoring maternal HR via MECG electrodes, but you are monitoring SpO2, the maternal pulse rate is derived from the SpO2 measurement. The pulse numeric is labeled Pulse on the screen. WARNING No QRS tone is audible when the CL SpO2 Pod is the source of the pulse rate. Adjusting the Heart Rate / Pulse Alarm Limits In the Setup SpO menu, select Pulse (SpO). This opens the Setup Pulse (SpO) menu. To adjust the pulse alarm limits for SpO2:
1 2 Ensure Pulse (SpO) is On. Select Pulse (SpO) to switch between On and Off. 3 Set the pulse alarm limit:
Select High Limit then choose the upper alarm limit for tachycardia from the pop-up list. Select Low Limit then choose the lower alarm limit for bradycardia from the pop-up list. In the Setup MECG menu, select MECG/Pulse Alarms. This opens the Setup Pulse (MECG) menu. To adjust the pulse alarm limits for MECG:
1 2 Ensure Pulse MECG is On. Select Pulse MECG to switch between On and Off. 3 Select High Limit then choose the upper alarm limit for tachycardia from the pop-up list. Select Low Limit then choose the lower alarm limit for bradycardia from the pop-up list. Set the pulse alarm limit. Average Pulse Rate from Noninvasive Blood Pressure WARNING No alarm is possible when noninvasive blood pressure is the source of the pulse rate. When you are measuring noninvasive blood pressure, the monitor can also calculate the average pulse rate. This occurs in either manual or automatic mode, when neither MECG, SpO2 nor pulse from Toco MP or CL Toco+ MP transducer are measured. The value is displayed on the screen, and printed on the trace. It is not the actual pulse value, but an average pulse rate, taken during the most recent noninvasive blood pressure measurement. The value is updated after each successive measurement. If you need a continuous measurement, you should monitor using MECG, SpO2, or pulse from Toco MP or CL Toco+ MP transducer. 228 20 Monitoring Maternal Heart / Pulse Rate Testing MECG Mode See the monitor's Service Guide. 229 20 Monitoring Maternal Heart / Pulse Rate 230 21 21Printing the ECG Waveform FM30/50 You can print the ECG wave onto the trace paper. If you are monitoring both DECG and MECG, both waves will be printed. The start of the wave recording is annotated above the wave with MECG for Maternal ECG, with DECG for Direct fetal ECG, and with 25 mm/sec below the wave. When only MECG and/or DECG are measured without any real-time recording, the 25 mm/sec recorder speed is printed in the trace header. WARNING 1 The fetal/maternal monitor is not a diagnostic ECG device. In particular, the display of fetal/
maternal ECG is intended only for evaluating signal quality for fetal/maternal heart rate as derived from the ECG waveform. When in doubt, it can be used to identify sources of compromised signal quality, such as noise or muscle artifacts. It can subsequently be used to verify the result of measures taken to resolve them
(e.g., checking ECG cable connections or adapting the fetal ArtifactSuppress configuration). The safety and effectiveness of the displayed fetal/maternal ECG waveform (i.e., P, QRS, and T segments) for evaluation of fetal/maternal cardiac status during labor have not been evaluated. The ECG waveform is printed along the bottom of the heart rate grid, and the three different possibilities look like this:

Separate: This recording mode gives you a six-second ECG strip on the fetal trace paper in fast printout mode. The real-time fetal trace recording is temporarily interrupted while the ECG strip prints. A new MECG header is printed to mark where the MECG wave starts, and a new trace header and FHR header mark when the fetal trace resumes. 232 The following trace shows the MECG waveform:
21 Printing the ECG Waveform FHR1 trace interrupted 1 2 MECG header 3 Recorder speed 4 FHR1 trace resume Overlap: This recording mode gives you a delayed six-second snapshot of the maternal and/or direct fetal ECG for documentation on the fetal strip, but without interrupting the fetal trace. It takes 5 minutes to print this six-second snapshot at a recorder speed of 3 cm/min. It is documented as if it was recorded at 25 mm/s. 233 21 Printing the ECG Waveform The following trace shows both the DECG and MECG waveforms:
1 FHR1 and FHR2 2 DECG header 3 MECG header 4 Recorder speed To make your choice:
1 Enter the Main Setup menu. Select Fetal Recorder to enter the Fetal Recorder menu. Select ECG Wave to switch between Separate and Overlap. 2 3 To print the ECG wave(s):
1 Select the Record ECG Wave SmartKey (configurable) and the recording trace is started. Or 1 Enter the Main Setup menu by selecting the SmartKey. Select Fetal Recorder to enter the Fetal Recorder menu. Select Record ECG Wave and the recording trace is started. Select the ECG Wave. Select Record ECG Wave in the ECG wave menu and the recording trace is started. 2 3 Or 1 2 234 22 22Monitoring Noninvasive Blood Pressure The noninvasive blood pressure measurement (NBP) is intended for use with maternal patients. This monitor uses the oscillometric method for measuring NBP. A physician must determine the clinical significance of the NBP information. Introducing the Oscillometric Noninvasive Blood Pressure Measurement Oscillometric devices measure the amplitude of pressure changes in the occluding cuff as the cuff deflates from above systolic pressure. The amplitude suddenly increases as the pulse breaks through the occlusion in the artery. As the cuff pressure decreases further, the pulsations increase in amplitude, reach a maximum (which approximates to the mean pressure), and then diminish. Studies show that, especially in critical cases (arrhythmia, vasoconstriction, hypertension, shock), oscillometric devices are more accurate and consistent than devices using other noninvasive measuring techniques. WARNING Intravenous infusion: Do not use the NBP cuff on a limb with an intravenous infusion or arterial catheter in place. This could cause tissue damage around the catheter when the infusion is slowed or blocked during cuff inflation. Skin Damage: Do not measure NBP in cases of sickle-cell disease or any condition where skin damage has occurred or is expected. Existing Wounds: Do not apply the cuff over a wound as this can cause further injury. Mastectomy: Avoid applying the cuff on the side of the mastectomy, as the pressure increases the risk of lymphedema. For patients with a bilateral mastectomy, use clinical judgement to decide whether the the benefit of the measurement outweighs the risk. 235 22 Monitoring Noninvasive Blood Pressure Unattended Measurement: Use clinical judgement to decide whether to perform frequent unattended blood pressure measurements. Too frequent measurements can cause blood flow interference potentially resulting in injury to the patient. In cases of severe blood clotting disorders frequent measurements increase the risk of hematoma in the limb fitted with the cuff. Temporary Loss of Function: The pressurization of the cuff can temporarily cause loss of function of monitoring equipment used simultaneously on the same limb. Measurement Limitations NBP readings can be affected by the position of the subject, their physiological condition, the measurement site, and physical exercise. Thus a physician must determine the clinical significance of the NBP information. The measurement may be inaccurate or impossible:
with excessive and continuous patient movement such as during contractions with cardiac arrhythmias with rapid blood pressure changes with severe shock or hypothermia that reduces blood flow to the peripheries with obesity, where a thick layer of fat surrounding a limb dampens the oscillations coming from if a regular arterial pressure pulse is hard to detect the artery on an edematous extremity Measurement Methods There are three measurement methods:
Manual - measurement on demand. Results are displayed for up to one hour. Auto - continually repeated measurements (between one and 120 minute adjustable interval). You can make a manual measurement between two measurements in Auto Mode. Sequence- up to four measurement cycles which run consecutively, with a number of measurements and intervals between them configurable for each cycle. Reference Method The measurement reference method can be Auscultatory (manual cuff) or Invasive (intra-arterial). For further information, see the Application Note supplied on the monitor documentation DVD. To check the current setting, select Main Setup, Measurements, NBP, and check whether the Reference setting is set to Auscultatory or Invasive. This setting can be changed in Configuration Mode. 236 Preparing to Measure Noninvasive Blood Pressure 22 Monitoring Noninvasive Blood Pressure If possible, avoid taking measurements during contractions, because the measurement may be unreliable, and may cause additional stress for the patient. 1 Connect the cuff to the air tubing. 2 Plug the air tubing into the red NBP connector. Avoid compression or restriction of pressure tubes. Air must pass unrestricted through the tubing. WARNING Kinked or otherwise restricted tubing can lead to a continuous cuff pressure, causing blood flow interference, and potentially resulting in injury to the patient. 3 Make sure that you are using a Philips-approved correct sized cuff, and that the bladder inside the cover is not folded or twisted. A wrong cuff size, and a folded or twisted bladder, can cause inaccurate measurements. The width of the cuff should be in the range from 37% to 47% of the limb circumference. The inflatable part of the cuff should be long enough to encircle at least 80% of the limb. 4 Apply the cuff to a limb at the same level as the heart. If it is not, you must use the measurement correction formula to correct the measurement. The marking on the cuff must match the artery location. Do not wrap the cuff too tightly around the limb. It may cause discoloration, and ischemia of the extremities. WARNING Inspect the application site regularly to ensure skin quality and inspect the extremity of the cuffed limb for normal color, warmth, and sensitivity. If the skin quality changes, or if the extremity circulation is being affected, move the cuff to another site, or stop the blood pressure measurements immediately. Check more frequently when making automatic measurements. Correcting the Measurement if Limb is not at Heart Level To correct the measurement if the limb is not at heart level, to the displayed value:
Add 0.75 mmHg (0.10 kPa) for each centimeter higher or Add 1.9 mmHg (0.25 kPa) for each inch higher. Deduct 1.9 mmHg (0.25 kPa) for each inch Deduct 0.75 mmHg (0.10 kPa) for each centimeter lower or lower. Recommendations For Measurements Used in Diagnosis of Hypertension To make a measurement for use in the diagnosis of hypertension, follow the steps below:
1 Ensure the patient is comfortably seated, with their legs uncrossed, feet flat on the floor, and back and arm supported. 2 Ask the patient to relax and not talk before and during the measurement. 3 If possible, wait 5 minutes before making the first measurement. 237 22 Monitoring Noninvasive Blood Pressure Understanding the Numerics 1 Alarm source 2 Measurement Mode 3 Timestamp/Timer 4 Mean pressure 5 Diastolic 6 Systolic 7 Alarm limits Depending on the numeric size, not all elements may be visible. Your monitor may be configured to display only the systolic and diastolic values. If configured to do so, the pulse from NBP is displayed with the NBP numeric. Aging Numerics The measured NBP value, together with the corresponding pulse rate, if this is switched on, are displayed for one hour. After that the values are regarded as invalid and are no longer displayed. During this time, measurement values may be grayed out, or disappear from the screen after a set time, if configured to do so. This avoids older numerics being misinterpreted as current data. The time can be set in Configuration Mode. In Auto Mode, the measurement values may disappear more quickly (to be replaced by new measurement values), if the repeat time is set to less than one hour. Alarm Sources If you have parallel alarm sources, the sources are displayed instead of the alarm limits. NBP Measurement Timestamp Depending on your configuration, the time shown beside the NBP numeric can be:
the time of the most recent NBP measurement, also known as the "timestamp", or the time until the next measurement in an automatic series, displayed with a graphic representation of the remaining time, as shown here. The NBP timestamp will normally show the completion time of the NBP measurement. NBP Measurement Start Time In Auto or Sequence mode, the monitor is configured to synchronize the measurements in a measurement series to an "easy-to-document" time. For example, if you start the first measurement at 08:23, and the Repeat Time is set to 10 min, the monitor automatically performs the next measurement at 8:30, then 8:40, and so on, unless it has been configured to NotSynchron.. During Measurements The cuff pressure is displayed instead of the units and the repeat time. An early systolic value gives you a preliminary indication of the systolic blood pressure during measurement. 238 Starting and Stopping Measurements 22 Monitoring Noninvasive Blood Pressure Use the setup menu or the SmartKeys to start and stop measurements.

Switch between Auto and Manual, if necessary, to pick the measurement method. If making an automatic measurement, select Repeat Time, or press the Repeat Time SmartKey and set the time interval between two measurements. NOTE Be aware that a combination of a recorder speed of less than 3 cm/min and a repetition time of less than five minutes can result in not all noninvasive blood pressure measurements being recorded on the fetal trace. For example, if the recorder speed is set to 1 cm/min and the repetition time is set to two minutes, due to the low speed setting, the recorder will only be able to record every other noninvasive blood pressure measurement. This affects only the local fetal trace recording, and all measurements are displayed as normal on the monitor's screen. 239 22 Monitoring Noninvasive Blood Pressure Enabling Sequence Mode and Setting Up the Sequence 1 2 3 In the Setup NBP menu, select Mode and select Sequence from the pop-up menu. Select Setup Sequence to open the Setup Sequence window. Up to four measurement cycles can be set up which run consecutively. For each cycle, you can set the number of measurements and the intervals between them. If you want to run fewer than four cycles in a sequence, you can set the number of measurements for one or more cycles to Off. Select each sequence in turn, and select the number of measurements and the time interval between the measurements. 4 To have measurements continue after the sequence, set the number of measurements for your last cycle to Continuous and this cycle will run indefinitely. CAUTION Be aware that, if none of the cycles are set to Continuous, NBP monitoring will end after the last measurement of the cycle. When the NBP measurement mode is set to Sequence, the repetition time for Auto Mode cannot be changed. Choosing the Alarm Source You can monitor for alarm conditions in systolic, diastolic, and mean pressure, either singly or in parallel. Only one alarm is given, with the priority of mean, systolic, diastolic. Menu option Sys. Dia. Mean Sys & Dia Dia & Mean Sys & Mean Sys&Dia&Mean Pressure value monitored systolic diastolic mean systolic and diastolic in parallel diastolic and mean in parallel systolic and mean in parallel all three pressures in parallel If mean is not selected as alarm source (Sys., Dia., or Sys & Dia selected), but the fetal monitor can only derive a mean value, mean alarms will nevertheless be announced using the most recent mean alarm limits. Check that the mean alarm limits are appropriate for the patient, even when not using mean as the alarm source. When no value can be derived, an NBP Measure Failed INOP is displayed. 240 Assisting Venous Puncture 22 Monitoring Noninvasive Blood Pressure In the Setup NBP menu, select VeniPuncture. Puncture vein and draw blood sample. You can use the cuff to cause subdiastolic pressure. The cuff deflates automatically after a set time if you do not deflate it. 1 2 3 Reselect VeniPuncture to deflate the cuff. During measurement, the display shows the inflation pressure of the cuff and the remaining time in venous puncture mode. 1 Cuff pressure 2 Venous puncture measurement mode 3 Time left in venous puncture mode Calibrating NBP NBP is not user-calibrated. NBP pressure transducers must be verified at least once every two years by a qualified service professional, and calibrated, if necessary. See the Service Guide for details. 241 22 Monitoring Noninvasive Blood Pressure Troubleshooting Possible Causes Monitor is in Service or Configuration Mode Technical defect Cuff tubing not connected Contraction occurring Patient talking before or during measurement Incorrect cuff size or cuff not at heart level Noninvasive blood pressure reference method set incorrectly Measurement limitations have not been taken into account Severe vasoconstriction at cuff site Erratic blood pressure fluctuations due to arrhythmias or rapid-acting drugs or contractions Solutions Call service Connect cuff tubing Wait until contraction has finished Allow patient to rest quietly, then try again after three to five minutes Check cuff size, level, and position Check the reference method configured

Philips pulse oximetry uses a motion-tolerant signal processing algorithm, based on Fourier Artifact Suppression Technology (FAST). It provides two measurements:
Oxygen saturation of arterial blood (SpO2) - percentage of oxygenated hemoglobin in relation to the sum of oxyhemoglobin and deoxyhemoglobin (functional arterial oxygen saturation). Pulse rate - detected arterial pulsations per minute. This is derived from the SpO2 value, and is one of four sources of the maternal heart/pulse rate used for cross-channel verification (see Monitoring Maternal Heart / Pulse Rate on page 221 and Cross-Channel Verification (CCV) on page 159). Selecting an SpO2 Sensor See Accessories and Supplies on page 275 for a list of sensors, and the patient population and application sites for which they are appropriate. Familiarize yourself with the Instructions for Use supplied with your sensor before using it. CAUTION Do not use OxiCliq disposable sensors in a high humidity environment, or in the presence of fluids, which may contaminate sensor and electrical connections causing unreliable or intermittent measurements. Do not use disposable sensors when there is a known allergic reaction to the adhesive. Applying the Sensor Follow the SpO2 sensor's Instructions for Use, adhering to all warnings and cautions. 1 2 Remove colored nail polish from the application site. 3 Apply the sensor to the patient. The application site should match the sensor size so that the sensor can neither fall off, nor apply excessive pressure. 4 Check that the light emitter and the photodetector are directly opposite each other. All light from the emitter must pass through the patient's tissue. 243 23 Monitoring SpO2 WARNING Compatibility: Use only the accessories that are specified for use with this fetal monitor, otherwise patient injury can result. Proper Sensor Fit: If a sensor is too loose, it might compromise the optical alignment or fall off. If it is too tight, for example because the application site is too large or becomes too large due to edema, excessive pressure may be applied. This can result in venous congestion distal from the application site, leading to interstitial edema, hypoxemia, and tissue malnutrition. Skin irritations or lacerations may occur as a result of the sensor being attached to one location for too long. To avoid skin irritations and lacerations, periodically inspect the sensor application site and change the application site regularly. Venous Pulsation: Do not apply sensor too tightly as this results in venous pulsation which may severely obstruct circulation and lead to inaccurate measurements. Ambient Temperature: At elevated ambient temperatures, be careful with measurement sites that are not well perfused, because this can cause severe burns after prolonged application. All listed sensors operate without risk of exceeding 41C on the skin if the initial skin temperature does not exceed 35C. Extremities to Avoid: Avoid placing the sensor on extremities with an arterial catheter, an NBP cuff, or an intravascular venous infusion line. Connecting SpO2 Cables Connect the sensor cable to the color-coded socket on the monitor. If you are using a disposable sensor, plug the sensor into the adapter cable and connect this to the monitor. Connect reusable sensors directly to the monitor. CAUTION Extension cables: Do not use more than one extension cable (M1941A). Do not use an extension cable with Philips reusable sensors or adapter cables with part numbers ending in -L (indicates "long"
cable version). Electrical Interference: Position the sensor cable and connector away from power cables, to avoid electrical interference. Measuring SpO2 During measurement, ensure that the application site:
has a pulsatile flow, ideally with a signal quality indicator of at least medium. has not changed in its thickness (for example, due to edema), causing an improper fit of the sensor. 244 23 Monitoring SpO2 WARNING For fully conscious maternal patients, who have a normal function of perfusion and sensory perception at the measurement site:
To ensure skin quality and correct optical alignment of the sensor, inspect the application site when the measurement results are suspicious, or when the patient complains about pressure at the application site, but at least every 24 hours. Correct the sensor alignment if necessary. Move the sensor to another site, if the skin quality changes. For all other patients:
Inspect the application site every two to three hours to ensure skin quality and correct optical alignment. Correct the sensor alignment if necessary. If the skin quality changes, move the sensor to another site. Change the application site at least every four hours. Injected dyes such as methylene blue, or intravascular dyshemoglobins such as methemoglobin and carboxyhemoglobin may lead to inaccurate measurements. Inaccurate measurements may result when the application site for the sensor is deeply pigmented or deeply colored, for example, with nail polish, artificial nails, dye, or pigmented cream. Interference can be caused by:
High levels of ambient light (including IR warmers), or strobe lights or flashing lights (such as fire alarm lamps). (Hint: cover application site with opaque material). Another SpO2 sensor in close proximity (e.g. when more than one SpO2 measurement is performed on the same patient). Always cover both sensors with opaque material to reduce cross-interference. Electromagnetic interference, especially when the signal quality indicator is below medium. Excessive patient movement and vibration. SpO2 Signal Quality Indicator (FAST SpO2 only) The SpO2 numeric is displayed together with a signal quality indicator (if configured and enough space is available) which gives an indication of the reliability of the displayed values. The level to which the triangle is filled shows the quality of the signal; the indicator below shows a medium signal quality. The signal quality is at a maximum when the triangle is completely filled. 245 23 Monitoring SpO2 Assessing a Suspicious SpO2 Reading Traditionally, pulse rate from SpO2 was compared with heart rate from ECG to confirm the validity of the SpO2 reading. With newer algorithms, such as FAST-SpO2, this is no longer a valid criteria because the correct calculation of SpO2 is not directly linked to the correct detection of each pulse. When the pulse rate is very low, or strong arrhythmia is present, the SpO2 pulse rate may differ from the heart rate calculated from ECG, but this does not indicate an inaccurate SpO2 value. WARNING With pulse oximetry, sensor movement, ambient light (especially strobe lights, or flashing lights), or electromagnetic interference can give unexpected intermittent readings when the sensor is not attached. Especially bandage-type sensor designs are sensitive to minimal sensor movement that might occur when the sensor is dangling. Understanding SpO2 Alarms This refers to SpO2 specific alarms. See the Alarms on page 117 chapter for general alarm information. SpO2 offers high and low limit alarms, and a high priority desat alarm. You cannot set the low alarm limit below the desat alarm limit. CAUTION If you measure SpO2 on a limb that has an inflated noninvasive blood pressure cuff, a non-pulsatile SpO2 INOP can occur. If the fetal monitor is configured to suppress this alarm, there may be a delay of up to 60 seconds in indicating a critical status, such as sudden pulse loss or hypoxia. Alarm Delays There is a delay between a physiological event at the measurement site and the corresponding alarm at the monitor. This delay has two components:
The general system delay time is the time between the occurrence of the physiological event and when this event is represented by the displayed numerical values. This delay depends on the algorithmic processing and the averaging time. The time between the displayed numerical values crossing an alarm limit and the alarm indication on the monitor. This delay is the combination of the configured alarm delay time plus the general system alarm signal delay time. Adjusting the SpO2 Alarm Limits In the Setup SpO menu:
Select High Limit then choose the upper alarm limit. Select Low Limit then choose the lower alarm limit. 246 23 Monitoring SpO2 Adjusting the Desat Limit Alarm The Desat alarm is a high priority (red) alarm notifying you of potentially life threatening drops in oxygen saturation. 1 2 Adjust the limit. In the Setup SpO menu, select Desat Limit. Adjusting the Pulse Alarm Limits See Adjusting the Heart Rate / Pulse Alarm Limits on page 228. Setting Up Tone Modulation If tone modulation is on, the QRS tone pitch lowers when the SpO2 level drops. Remember, the QRS tone is derived from either heart rate (from MECG or the CL F&M Pod) or pulse (from built-in SpO2) depending on which is currently displayed (see Priority for Maternal Heart / Pulse Rate on page 221). NOTE Pulse from CL SpO2 and Toco MP does not provide a QRS tone. Setting the QRS Volume In the Setup SpO menu, select QRS Volume and set the appropriate QRS tone volume. 247 23 Monitoring SpO2 248 24 24Monitoring Maternal Temperature Measuring Tympanic Temperature The tympanic thermometer (866149) measures the patient's temperature in the ear using infrared technology. The result of this measurement can be automatically adjusted to correspond to a different body reference site. The result is displayed on the screen of the thermometer and transmitted to the monitor. The thermometer is used with single-use probe covers for infection control during measurement. WARNING Do not use in the presence of flammable anesthetics, such as a flammable anesthetic mixture with air, oxygen, or nitrous oxide. 249 24 Monitoring Maternal Temperature Base station 1 2 Thermometer Place the thermometer into its base station, when it is not in use. The base station allows flexible mounting of the thermometer at the point of care. The base station is connected to the monitor's MIB/RS232 interface (optional) with a cable. It has storage space for up to 32 probe covers. Thermometer Display and Controls The tympanic thermometer has a liquid crystal display. The display shows the patient's temperature in numerics and guides you with symbols through the measurement process. 1 Eject key 2 Change unit key: Celsius/Fahrenheit 3 4 Start measurement key Pulse timer key Functional Keys Description of Use Press the eject key to eject the probe cover.

Status Screens The thermometer performs an internal test at every start-up to verify that the system components are functioning properly. It measures the ambient temperature. During start-up and measurement, the thermometer screens communicate the current status. Images Description Ambient temperature above specified range Ambient temperature below specified range System errors System error 12 - there is a problem with the settings. Contact your service personnel to have them check the settings and reset them, if necessary. If the display shows any other system error, then reset the thermometer by picking up a probe cover. If the system error does not clear, contact your service personnel. 251 24 Monitoring Maternal Temperature Making a Temperature Measurement WARNING Inaccurate measurement results can be caused by:
incorrect application of the thermometer anatomical variations in the ear build up of earwax in the ear excessive patient movement during the measurement absent, defective, or soiled probe covers probe covers other than the specified probe covers external environment temperature outside the range of 16C-33C (60.8F-91.4F) 1 Ensure that the base station is connected with the appropriate cable to the connector on the monitor. 2 Remove the thermometer from the base station. The thermometer is latched to the base station to avoid an accidental fall when the base station is moved. To pick up the thermometer from the base station move it slightly up, and then lift it from the base station to release the latch. Press the eject key on the thermometer to discard any probe that may have been left on the thermometer from a previous use. Pick up a new probe cover from the container on the base station. Inspect the probe cover to make sure that it is fully seated (no space between cover and tip base) and that there are no holes, tears, or wrinkles in the plastic film. Place the thermometer with the probe in the ear canal, sealing the opening with the probe tip. For consistent results, ensure that the probe shaft is aligned with the ear canal. Press and release the start-up key gently. 3 4 5 6 7 8 Wait until you hear the three beeps. 9 Remove the probe from the ear. The temperature values are displayed both on the thermometer itself, and on the connected monitor. 10 Check that the correct temperature label for the measurement site is displayed: iTrect, iToral, iTcore, or iTtymp. 11 Press the eject key to eject the probe cover into a suitable waste receptacle. 12 Return the thermometer to the base station. The thermometer switches to stand-by mode after 30 seconds when it is not used. 252 24 Monitoring Maternal Temperature Possible INOPs Images Description Patient temperature above measurement range. Patient temperature below measurement range. WARNING Never apply the probe to the patient when the thermometer is not connected to the base station. Always use a single-use probe cover to limit patient cross-contamination. Measurement errors or inaccurate readings may result when probe covers other than the specified probe covers are used (see Tympanic Temperature Accessories on page 285). Insert the probe slowly and carefully to avoid damage to the ear canal and the tympanic membrane. Inspect the probe cover for damage, holes, tears, or sharp edges to avoid injuring the skin. Always ensure that the used probe cover is removed before attaching a new probe cover. CAUTION Do not immerse the probe in fluids, or drop fluids on the probe. Do not use a probe cover that has been dropped or is damaged. Do not autoclave. To prevent damage to the base station, thermometer and accessories, refer to the cleaning procedures in the Care and Cleaning on page 261 chapter. WARNING If you have dropped the base station or thermometer, or if the unit has been stored below -25C or above 55C, have service personnel test the unit for proper functions, and calibrate the unit before further use. The Value Lifetime (length of time the entered value is shown on the screen) can be configured in Configuration Mode. 253 24 Monitoring Maternal Temperature Body Reference Sites and Monitor Labels The tympanic thermometer measures the patient's temperature in the ear. The thermometer can be configured to adjust the result of the measurement to correspond to a different body reference site. The measurement label displayed on the monitor corresponds to the body reference site that is configured. The following body reference sites are available:
Body Reference Site Ear temperature (no adjustment) Oral temperature Core temperature Rectal temperature Label on Monitor iTtymp iToral iTcore iTrect The body reference site can be selected in the Biomed mode of the tympanic thermometer. Refer to the Service Guide for more information. The measured maternal temperature is only transmitted to a connected OB TraceVue/IntelliSpace Perinatal system, when the tympanic thermometer is configured to the iTtymp body reference site, and the iTtymp label is displayed on the fetal monitor screen, and printed on the trace. Entering Temperature Manually A temperature measurement can be entered manually. 1 Press the SmartKey Enter Temp (configurable) or select the SmartKey Main Setup, then select Measurements, Enter Temp. A numeric pad opens. Select the Enter key. 2 Enter the temperature values. 3 Interval Use the Interval setting to define the time after which a manually entered temperature value becomes invalid (no value is then displayed). NOTE A manually entered temperature has to be 25C or higher to be transmitted to a connected obstetrical information and surveillance system. 254 25 25Paper Save Mode for Maternal Measurements Your monitor's recorder features a Paper Save Mode, where maternal vital signs are recorded using less paper than during a normal trace recording. When Paper Save Mode is enabled, and if the recorder is stopped, it will start automatically to print data from maternal measurements as they occur, and then stops again to save paper. You enable Paper Save Mode in Configuration Mode (default is off). A header is printed first before the measurements are recorded. A new header is also printed when there is a date change at midnight. Each NBP measurement is recorded. The time when the measurement ended is recorded. Each Temperature measurement is recorded. The time when the measurement ended is recorded. Other maternal parameters (SpO2, maternal heart rate, or Pulse) are recorded every five minutes. The rules described in the section Priority for Maternal Heart / Pulse Rate on page 221 apply. Paper Save Mode recording stops if there are no valid maternal measurements for more than one hour, and a message will notify you that there are no active parameters. Paper Save Mode recording will restart automatically when another valid measurement is made. Event One of the maternal measurements (see above) is valid again. The recorder is turned off and on again or a report has been recorded
(e.g. NST Report). The Paper Advance function is used. The Paper Save Mode setting is set off and on again. ADT information has changed (e.g. because patient information has been completed or updated). The monitor is restarted (e.g. by switching it off and on again). The date has changed (e.g. at midnight). Paper Save Mode Reactivation yes yes yes yes no yes no 255 25 Paper Save Mode for Maternal Measurements 256 26 26Recovering Data The monitor stores trace data, including annotations, for a minimum of 3.5 hours with the software revision J.3 or higher, and for a minimum of 7 hours with the new mainboard hardware revision A 00.18, in its internal backup memory. This allows the monitor to recover trace data that would otherwise be lost under certain circumstances. In the event of the paper running out, this trace recovery data can be automatically retrieved and printed, or automatically transmitted to an OB TraceVue/IntelliSpace Perinatal system (LAN connection only), allowing continuity of data. The fetal trace printed from the trace recovery data contains all data from the real-time trace. Note that the data in the memory is cleared when a software upgrade is performed. CAUTION Only use Philips paper. Using paper other than Philips paper may result in the failure to recover traces. Recovering Traces on Paper The monitor is able to recover traces by printing them out at a high speed from the monitor's backup memory. If the monitor runs out of paper, or if the paper drawer is open, the exact time when this happens is stored in the backup memory. If the Bridge Paperout setting is set to On (default), when new paper is loaded and the recorder is started, a trace recovery printout of the data recovered from the backup memory is automatically printed out at high speed (up to 20 mm/s), starting from the time noted in the backup memory. This ensures that no data is lost. A minimum of one hour of trace recovery data is available for printing out from the backup memory. When the trace recovery printout has finished, the recorder automatically switches back to continue recording the current trace at the normal speed. Note the following:
If you press the fetal recorder Start/ Stop SmartKey during a trace recovery printout, the recording stops, and the next recording following a recorder restart will be a normal, real-time trace. After switching off the monitor, and then back on again, or following a power failure, the time of the last Check Paper INOP or paper-out detection is lost, and therefore any trace recovery data in the backup memory is no longer available to print. The next recording made following a restart of the recorder is a normal, real-time trace. 257 26 Recovering Data The change back to a real-time recording from a trace recovery printout prompts the recording to restart. A new vertical trace header annotation consisting of the time, date, and recorder speed is printed, letting you see where the trace recovery printout ends, and where the real-time trace continues. There can be a gap of up to 30 seconds between the trace recovery printout, and the beginning of the real-time trace. Recovering Traces on an OB TraceVue/IntelliSpace Perinatal System The trace recovery data stored in the monitor's backup memory can also be uploaded at high speed to an OB TraceVue/IntelliSpace Perinatal system connected over the LAN interface (OB TraceVue Revision E.00.00 or later, and IntelliSpace Perinatal H.0 or later). When the OB TraceVue/IntelliSpace Perinatal system reconnects to the fetal monitor and detects that there is trace recovery data in the monitor's backup memory that has not yet been transmitted to the system, this data is transferred at high speed to the system. No user action is required. The exact length of the recovered trace will vary depending on the amount of trace information, but it will cover at least 3.5 hours of trace data with the software revision J.3 or higher, and 7 hours with the new mainboard hardware revision A 00.18, depending on the number of active parameters. To recover traces on an OB TraceVue/IntelliSpace Perinatal system, the following applies:
The trace data in the monitor's internal memory must relate to a specific patient in the OB TraceVue/IntelliSpace Perinatal system. In other words, there were no discharge events made on the monitor that would change the patient context. The patient must have an open episode. No data will be uploaded if the patient is not admitted to OB TraceVue/IntelliSpace Perinatal. For further details see the OB TraceVue/IntelliSpace Perinatal Instructions for Use. Current online trace data is held back until the fast upload is complete. Manually Recording Stored Data If the recorder is not running, you can choose to print trace data from the monitor's memory at any time. You can see a list of all stored traces, showing patient identification and trace period, in the Stored Data Recording window, from which you can choose one of the entries at a time. CAUTION Ensure that you admit each patient by name, including other patient identification information, and discharge the patient when you have finished monitoring, so that you can identify which trace period
(entry in the patient list) refers to which patient. Trace storage can be triggered by:
Discharging a patient Entering Standby Entering Service Mode Powering on the monitor 258 26 Recovering Data Traces are not available for periods the monitor was switched off, in Service Mode, in Standby, or if the trace period was shorter than one minute. The speed of the printout depends on the configured recorder speed and on the amount of trace data available. The fetal trace printed from the trace data contains all data from the real-time trace, with the exception of the maternal heart rate, the pulse numeric, and the ECG wave. Information for scale type, trace separation, and recorder speed are not stored in the trace memory, but is applied when the stored recording starts. While the stored recording is printing, all functions are disabled, except that for stopping the recorder. To start a stored data recording:
Either 1 Select the Stored Data Rec SmartKey. 2 Select All to print all stored trace data for the selected entry, or select one of the choices on the other pop-up keys to print only a specified portion of the entry (for example, Last 15 min for the last 15 minutes of trace data). Or 1 Enter the Main Setup menu using the SmartKey. 2 3 4 5 Select Fetal Recorder to open the Fetal Recorder menu. Select Stored Data Rec to open the Stored Data Recording window. Select an entry for a patient. Select All to print all stored trace data for the selected entry, or select one of the choices on the other pop-up keys to print only a specified portion of the entry (for example, Last 15 min for the last 15 minutes of trace data). To delete all stored trace periods:
Either 1 Select the Stored Data Rec SmartKey. Select the Erase All key to delete all stored trace periods listed. Select the Confirm key. 2 3 Or 1 Enter the Main Setup menu using the SmartKey. 2 3 4 5 Select Fetal Recorder to open the Fetal Recorder menu. Select Stored Data Rec to open the Stored Data Recording window. Select the Erase All key to delete all stored trace periods listed. Select the Confirm key. 259 26 Recovering Data The current patients entry is at the top of the list. The oldest entry at the bottom of the list has no start time specified, as part of the data originally stored may have been over-written by the current patients data. It may be that you only see one entry (the current patients data) in the Stored Data Recording window if that patient was monitored for a period long enough to erase any earlier entries. If you make a stored data recording for an old entry (that is, not for the current patient), the recorder performs a fast trace printout of the stored data, advances the paper to the next paper fold, then stops. If you make a stored data recording for the current patient, the recorder performs a fast trace printout of the stored data, and then reverts automatically to recording the real-time trace. 260 27 27Care and Cleaning Use only the Philips-approved substances and methods listed in this chapter to clean or disinfect your equipment.

Storing Recorder Paper Recorder paper is not intended for long-term archival storage. Another medium should be considered if this is required. Dyes contained in thermal papers tend to react with solvents and other chemical compounds that are being used in adhesives. If these compounds come into contact with the thermal print, the print may be destroyed over time. You can take the following precautionary measures to help avoid this effect:
Do not store the paper at temperatures over 40C (104F). Do not store the paper where the relative humidity exceeds 60%. Avoid intensive light (UV light), as this may cause the paper to turn gray, or the thermal print to Store the paper in a cool, dry, and dark place. fade. Avoid storing the thermal paper in combination with the following conditions:
Papers that contain organic solvents. This includes papers with tributyl and/or dibutyl phosphates, for example recycled paper. Carbon paper and carbonless copy paper. Products containing polyvinyl chlorides, or other vinyl chlorides for example (but not exclusively) document holders, envelopes, letter files, divider sheets. Detergents and solvents, such as alcohol, ketone, ester, and others, including cleaning and disinfecting agents. Products containing solvent-based adhesives such as (but not exclusively) laminating film, transparent film, or labels sensitive to pressure. To ensure long lasting legibility and durability of thermal printouts, store your documents separately in an air-conditioned place and use:
Using such protective envelopes cannot prevent the fading effect caused by other, external agents. only plasticizer-free envelopes or divider sheets for protection. laminating films and systems with water-based adhesives. 272 Cleaning the Print Head 28 Maintenance To clean the recorder's thermal print-head:

In particular, the display of fetal/maternal ECG is intended only for evaluating signal quality for fetal/maternal heart rate as derived from the ECG waveform. When in doubt, it can be used to identify sources of compromised signal quality, such as noise or muscle artifacts. It can subsequently be used to verify the result of measures taken to resolve them
(e.g., checking ECG cable connections or adapting the fetal ArtifactSuppress configuration).

EN 60601-1:2006+AC:2013) that ensures mechanical fixing of the power cords and covering of any unused power outlets. Do not use USB devices with own power supplies, unless an appropriate separation device is used,
(either between USB interface and device or between device and power). During the installation the fetal monitor is configured for your environment. This configuration defines your custom default settings you work with when you switch on your fetal monitor. See the fetal monitor's Service Guide and the Configuration Guide for details on how to configure your fetal monitor. 312 Electromagnetic Compatibility (EMC) 30 Specifications and Standards Compliance IEC 60601-1-2:2007 / EN 60601-1-2:2007+AC:2010 The device and its accessories, listed in the accessories section, comply with the following EMC standards:
Take special precautions regarding electromagnetic compatibility (EMC) when using medical electrical equipment. You must operate your monitoring equipment according to the EMC information provided in this book. Before using the device, assess the electromagnetic compatibility of the device with surrounding equipment. This ISM device complies with Canadian ICES-003:2012. Cet appareil ISM est conforme la norme NMB-003 du Canada. CAUTION FM20/FM30 only: Although this is an electrical Class II device, it has a protective earth conductor which is needed for EMC purposes. Always use the supplied power cord with the three-prong plug to connect the monitor to AC mains. Never adapt the three-prong plug from the power supply to fit a two-slot outlet. WARNING The use of accessories, transducers, and cables other than those specified, may result in increased electromagnetic emissions, or decreased electromagnetic immunity of the device. WARNING Do not use cordless/mobile phones, or any other portable RF communication system within the patient vicinity, or within a 1.0 m radius of any part of the fetal monitoring system. WARNING For paced patients: The radiated SRR power of the CL SpO2 and CL NBP Maternal Cableless Measurement Devices, and other sources of radio-frequency energy, when used in very close proximity of a pacemaker, might be sufficient to interfere with pacemaker performance. Due to shielding effects of the body, internal pacemakers are somewhat less vulnerable than external pacemakers. However, caution should be exercised when monitoring paced patients. In order to minimize the possibility of interference, avoid positioning and wearing the Cableless Measurement Devices in very close proximity to a pacemaker. Consult the pacemaker manufacturer for information on the RF susceptibility of their products. 313 30 Specifications and Standards Compliance EMC Testing CAUTION Fetal parameters, especially ultrasound and ECG, are sensitive measurements involving small signals, and the monitoring equipment contains very sensitive high gain front-end amplifiers. Immunity levels for radiated RF electromagnetic fields and conducted disturbances induced by RF fields are subject to technological limitations. To ensure that external electromagnetic fields do not cause erroneous measurements, it is recommended to avoid the use of electrically radiating equipment in close proximity to these measurements. Reducing Electromagnetic Interference WARNING The device should not be used adjacent to, or stacked with, other equipment unless otherwise specified. The product and associated accessories can be susceptible to interference from continuous, repetitive, power line bursts, and other RF energy sources, even if the other equipment is compliant with EN 60601-1-2 emission requirements. Examples of other sources of RF interference are other medical electrical devices, cellular products, information technology equipment, and radio/television transmissions. When electromagnetic interference (EMI) is encountered, for example, if you can hear spurious noises on the fetal monitor's loudspeaker, attempt to locate the source. Assess the following:
Is the interference due to misplaced or poorly applied transducers? If so, re-apply transducers correctly according to directions in this book, or in the Instructions for Use accompanying the accessory. Is the interference intermittent or constant?
Does the interference occur only in certain locations?
Does the interference occur only when in close proximity to certain medical electrical equipment?
Once the source is located, there are a number of things that can be done to mitigate the problem:
1 Eliminating the source. Turn off or move possible sources of EMI to reduce their strength. 2 Attenuating the coupling. If the coupling path is through the patient leads, the interference may be reduced by moving and/or rearranging the leads. If the coupling is through the power cord, connecting the system to a different circuit may help. 3 Adding external attenuators. If EMI becomes an unusually difficult problem, external devices such as an isolation transformer or a transient suppressor may be of help. Your service provider can be of help in determining the need for external devices. Where it has been established that electromagnetic interference is affecting physiological parameter measurement values, a physician, or a suitably qualified person authorized by a physician, should determine if it will negatively impact patient diagnosis or treatment. 314 30 Specifications and Standards Compliance System Characteristics The phenomena discussed above are not unique to this system, but are characteristic of fetal patient monitoring equipment in use today. This performance is due to very sensitive high gain front end amplifiers required to process the small physiological signals from the patient. Among the various monitoring systems already in clinical use, interference from electromagnetic sources is rarely a problem. Electromagnetic Emissions and Immunity The EMC standards state that manufacturers of patient-coupled equipment must specify immunity levels for their systems. See Tables 1 to 4 for this detailed immunity information. See Table 5 for recommended minimum separation distances between portable and mobile communications equipment and the product. Immunity is defined in the standard as the ability of a system to perform without degradation in the presence of an electromagnetic disturbance. Caution should be exercised in comparing immunity levels between different devices. The criteria used for degradation are not always specified by the standard, and can therefore vary with the manufacturer. In the table below, the term "device" refers to the Avalon FM20/30/40/50 fetal monitor together with its accessories. The table gives details of the electromagnetic emissions, and how these are classified, for the device, and the electromagnetic environments in which the device is specified to technically function. Table 1 - Guidance and Manufacturer's Declaration: Electromagnetic Emissions Emissions Test Radiofrequency (RF) emissions Compliance Group 1 Avoiding Electromagnetic Interference The device uses RF energy only for its internal function. Therefore, its RF emissions are very low and are not likely to cause any interference in nearby electronic equipment.

Alternatively, it can be used with any accessory that positions the front side of the device a minimum of 10 mm from the body. The accessory itself must not contain any metal parts. Use of other accessories may not ensure compliance with FCC RF exposure guidelines. Nevertheless it is strongly recommended to operate the CL Wide Range Pod with the rear side towards the body to achieve best possible radio performance. 320 Environment 30 Specifications and Standards Compliance Before operation, make sure that the fetal monitor is free from condensation. This can form when equipment is moved from one building to another, and is exposed to moisture and differences in temperature. Use the monitor in an environment which is reasonably free from vibration, dust, corrosive or explosive gasses, extremes of temperature, humidity, and so forth. It operates within specifications at ambient temperatures between 0-+45C (32F-113F). Ambient temperatures that exceed these limits can affect the accuracy of the system, and can damage the components and circuits. Ambient temperature ranges for storage are -20C-+60C (-4F-140F) for the monitor, and -40C-
+60C (-40F-140F) for transducers. The transducers are watertight to a depth of 1.0 m for at least five hours (rated IP 68). WARNING Leakage currents: If several items of equipment used to monitor a patient are interconnected, the resulting leakage current may exceed allowable limits. ECG electrodes: NEVER allow ECG electrodes to contact other electrical conductive parts, including earth. Monitoring After a Loss of Power If the monitor is without power for less than one minute, monitoring will resume with all active settings unchanged. If the monitor is without power for more than one minute, the behavior depends on your configuration. If Automat. Default is set to Yes, the User Defaults will be loaded when power is restored. If Automat. Default is set to No, all active settings are retained, if power is restored within 48 hours. The Automat. Default setting is made in Configuration Mode.
