Product Description The Radical-7 is a noninvasive monitor that measures arterial oxygen saturation (SpO2), pulse rate (PR), and perfusion index (PI), along with optional measurements of hemoglobin
(SpHb), carboxyhemoglobin (SpCO), total oxygen content (SpOC), methemoglobin (SpMet), Pleth Variability Index (PVI), Acoustic Respiration Rate (RRa), and Pleth Respiration Rate
(RRp). The Radical-7 can be used as either a Handheld or a Standalone monitor. The Radical-7 features a touchscreen Liquid Crystal Display (LCD) that continuously displays numeric values for all parameters. The Radical-7 provides graphical displays for plethysmographic waveform, respiratory waveform, Signal Identification and Quality Indicator (Signal IQ). The Radical-7 can also be used to interface with a multi-parameter patient monitor to send Masimo SET pulse oximetry information to that monitor for display. The Radical-7 has an embedded 802.11 wireless radio that can be used for connectivity. Key Features The following features are available for the Radical-7. Some features are optional:
Masimo SET is clinically proven to satisfy all sensitivity and specificity requirements for pulse oximeter technology. Rainbow technology uses 7+ wavelengths of light to continuously and noninvasively measure carboxyhemoglobin (SpCO), methemoglobin (SpMet), and total hemoglobin (SpHb), as well as providing a more reliable probe-off detection. Total oxygen content (SpOC) provides a calculated measurement of the amount of oxygen in arterial blood, which may provide useful information about oxygen both dissolved in plasma and combined with hemoglobin. Perfusion Index (PI) with trending capability indicates arterial pulse signal strength and may be used as a diagnostic tool during low perfusion. Pleth Variability Index (PVI) may show changes that reflect physiologic factors such as vascular tone, circulating blood volume, and intrathoracic pressure excursions. [The utility of PVI is unknown at this time and requires further clinical studies. Technical factors that may affect PVI include probe malposition and patient motion.]
Respiration rate can be determined by the acoustic (RRa) or plethysmographic waveform (RRp). www.masimo.com 9 Masimo Radical-7 Product Description, Indications for Use, Contraindications, and Features Signal IQ waveform for signal identification and quality indication during excessive motion and low signal to noise situations. FastSat tracks rapid changes in arterial O2. Variable pitch provides tonal variance for every 1% change in saturation. SatShare interface allows transfer of SpO2 and pulse rate to an existing multi-parameter monitor and allows for the reading of SpCO, SpMet, SpHb, and SpOC on adjacent Radical-7 monitor. Automatic screen rotation provides upright display for vertical or horizontal monitor positioning. Multi-gesture touchscreen interface. Detachable portable Handheld for patient transport. Remote alarm interface. Indications for Use The Masimo Radical-7 and accessories are indicated for the continuous noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2), pulse rate (PR), carboxyhemoglobin saturation (SpCO), methemoglobin saturation (SpMet), total hemoglobin concentration (SpHb), and/or respiratory rate (RRa). The Masimo Radical-7 and accessories have been validated and are indicated for use with adult, pediatric, and neonatal patients during both no motion and motion conditions, and for patients who are well or poorly perfused in hospitals, hospital-type facilities, mobile, and home environments. In addition, the Masimo Radical-7 and accessories are indicated to provide the continuous noninvasive monitoring data obtained from the Masimo rainbow SET Radical 7 Pulse CO-Oximeter and accessories of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR) to multi-parameter devices for the display of those devices.

Failure to follow all of the directions in this manual could lead to inaccurate measurements. Caution For SpHb, the Radical-7 should be considered an early warning device. Blood samples should be analyzed by laboratory instruments prior to clinical decision making to completely understand the patients condition. Caution Variation in hemoglobin measurements may be profound and may be affected by sample type, body positioning, as well as other physiological conditions. As with most hemoglobin tests, Radical-7 test results should be scrutinized in light of a specific patients condition. Any results exhibiting inconsistency with the patients clinical status should be repeated and/or supplemented with additional test data. Parameter Related Safety Information, Warnings, and Cautions This section contains parameter related safety information. Warning Interfering Substances: Dyes, or any substance containing dyes, that change usual blood pigmentation may cause erroneous readings. Warning SpO2, SpCO, SpMet, and SpHb are empirically calibrated in healthy adult volunteers with normal levels of carboxyhemoglobin (COHb) and methemoglobin (MetHb). www.masimo.com 11 Masimo Radical-7 Safety Information, Warnings, and Cautions Warning The Radical-7 cannot measure elevated levels of COHb or MetHb. Warning Inaccurate SpO2 readings may be caused by:
Elevated levels of COHb and MetHb For increased COHb: COHb levels above normal tend to increase the level of SpO2. The level of increase is approximately equal to the amount of COHb that is present. Note: High levels of COHb may occur with a seemingly normal SpO2. When elevated levels of COHb are suspected, laboratory analysis (CO-Oximetry) of a blood sample should be performed. For increased MetHb: the SpO2 may be decreased by levels of MetHb of up to approximately 10% to 15%. At higher levels of MetHb, the SpO2 may tend to read in the low to mid 80s. When elevated levels of MetHb are suspected, laboratory analysis (CO-Oximetry) of a blood sample should be performed. Intravascular dyes such as indocyanine green or methylene blue Externally applied coloring and texture such as nail polish, acrylic nails, glitter, etc. Elevated levels of bilirubin Severe anemia Low arterial perfusion Motion artifact www.masimo.com 12 Masimo Radical-7 Safety Information, Warnings, and Cautions Warning Inaccurate SpHb and SpOC readings may be caused by:
Motion artifact Intravascular dyes such as indocyanine green or methylene blue Externally applied coloring and texture such as nail polish, acrylic nails, glitter, etc. Elevated levels of bilirubin Low arterial perfusion Low arterial oxygen saturation levels Elevated carboxyhemoglobin levels Elevated methemoglobin levels Difference between patient's finger skin and finger core temperature Hemoglobin synthesis disorders Hemoglobinopathies and synthesis disorders such as thalassemias, Hb s, Hb c, sickle cell, etc. Vasospastic disease such as Raynaud's Elevated altitude Peripheral vascular disease Liver disease EMI radiation interference Warning Inaccurate SpCO and SpMet readings can be caused by:
Intravascular dyes such as indocyanine green or methylene blue Abnormal hemoglobin levels Low arterial perfusion Low arterial oxygen saturation levels including altitude induced hypoxemia Elevated total bilirubin levels Motion artifact SpCO readings may not be provided if SpO2 readings are less than 90%
SpCO readings may not be provided if SpMet readings are greater than 2%
Inaccurate SpCO readings can be caused by:
Levels of methemoglobin approximately 1.5% or above www.masimo.com 13 Masimo Radical-7 Safety Information, Warnings, and Cautions Warning Inaccurate respiration rate measurements may be caused by:
Low arterial perfusion Motion artifact Low arterial oxygen saturation Excessive ambient or environmental noise Improper sensor placement Caution If patient hypoxemia is indicated, blood samples should be analyzed by laboratory devices to completely understand the patients condition. Caution Confirm offset values(s) periodically as the difference between the displayed parameter value and the laboratory reference value may vary over time. Caution Do not use In Vivo Adjustment if the monitor displays a Low SpHb SIQ message. Caution If the Low Perfusion message is frequently displayed, find a better perfused monitoring site. In the interim, assess the patient and, if indicated, verify oxygenation status through other means. Caution Changing the SpHb Cal, the date and time of the system clock, or the trend period clears the data in the trend memory. Caution Excessive ambient noise may affect the accuracy of the respiration rate reading from the Acoustic Respiration Sensor. When monitoring acoustic respiration, Masimo recommends minimally monitoring both oxygenation (SpO2) and respiration (RRa).

Sensor Related Safety Information, Warnings, and Cautions This section contains sensor related safety information. Warning As with all medical equipment, carefully route patient cabling to reduce the possibility of patient entanglement or strangulation. Warning Always remove the sensor from the patient and completely disconnect the patient from the Radical-7 before bathing the patient. Caution If using the Radical-7 during full body irradiation, keep the sensor out of the radiation field. If the sensor is exposed to the radiation, the reading might be inaccurate or the instrument might read zero for the duration of the active irradiation period. Do not loop the sensor cable into a tight coil or wrap around the device, as this can damage the sensor cable. Patient Safety - If a sensor is damaged in any way, discontinue use immediately. Failure to apply the sensor properly may lead to incorrect measurements. Additional information specific to the Masimo sensors compatible with Radical-7, including information about parameter/measurement performance during motion and low perfusion, may be found in the sensor's directions for use (DFU). www.masimo.com 21 Masimo Radical-7 Safety Information, Warnings, and Cautions Do not expose the Masimo sensors used with Radical-7 to moisture, liquids or a humid environment, as this may make the sensor perform inaccurately or fail. High-intensity extreme lights (including pulsating strobe lights and direct sunlight) directed on the sensor, may not allow the Radical-7 to obtain readings. When using the Maximum Sensitivity setting, performance of the Sensor Off detection may be compromised. If the Radical-7 is in this setting and the sensor becomes dislodged from the patient, the potential for false readings may occur due to environmental "noise" such as light, vibration, and excessive air movement. www.masimo.com 22 Masimo Chapter 1: Technology Overview The following chapter contains general descriptions about parameters, measurements, and the technology used by Masimo products. Signal Extraction Technology (SET) Masimo Signal Extraction Technology's signal processing differs from that of conventional pulse oximeters. Conventional pulse oximeters assume that arterial blood is the only blood moving (pulsating) in the measurement site. During patient motion, however, the venous blood also moves, causing conventional pulse oximeters to read low values, because they cannot distinguish between the arterial and venous blood movement (sometimes referred to as noise). Masimo SET pulse oximetry utilizes parallel engines and adaptive digital filtering. Adaptive filters are powerful because they are able to adapt to the varying physiologic signals and/or noise and separate them by looking at the whole signal and breaking it down to its fundamental components. The Masimo SET signal processing algorithm, Discrete Saturation Transform (DST), in parallel with Fast Saturation Transform (FST), reliably identifies the noise, isolates it and, using adaptive filters, cancels it. It then reports the true arterial oxygen saturation for display on the monitor. Masimo rainbow SET Parallel Engines This figure is for conceptual purposes only. www.masimo.com 23 Masimo Radical-7 Masimo SET DST This figure is for conceptual purposes only. Chapter 1: Technology Overview General Description for Oxygen Saturation (SpO2) Pulse oximetry is governed by the following principles:
1. Oxyhemoglobin (oxygenated blood) and deoxyhemoglobin (non-oxygenated blood) differ in their absorption of red and infrared light (spectrophotometry). The amount of arterial blood in tissue changes with your pulse
(photoplethysmography). Therefore, the amount of light absorbed by the varying quantities of arterial blood changes as well. 2. 3. As a plethysmographic waveform Successful Monitoring for SpO2, PR, and PI Stability of the SpO2 readings may be a good indicator of signal validity. Although stability is a relative term, experience will provide a good feeling for changes that are artifactual or physiological and the speed, timing, and behavior of each. The stability of the readings over time is affected by the averaging mode being used. The longer the averaging time, the more stable the readings tend to become. This is due to a dampened response as the signal is averaged over a longer period of time than during shorter averaging times. However, longer averaging times delay the response of the oximeter and reduce the measured variations of SpO2 and pulse rate. Functional Oxygen Saturation The Radical-7 is calibrated to measure and display functional oxygen saturation (SpO2): the amount of oxyhemoglobin expressed as a percentage of the hemoglobin that is available to transport oxygen. Note that carboxyhemoglobin is not capable of transporting oxygen, but is recognized as oxygenated hemoglobin by conventional pulse oximetry. www.masimo.com 24 Masimo Radical-7 General Description for Pulse Rate (PR) Chapter 1: Technology Overview Pulse rate (PR) , measured in beats per minute (BPM) is based on the optical detection of peripheral flow pulse. General Description for Perfusion Index (PI) The Perfusion Index (PI) is the ratio of the pulsatile blood flow to the non-pulsatile or static blood in peripheral tissue. PI thus represents a noninvasive measure of peripheral perfusion that can be continuously and noninvasively obtained from a pulse oximeter. General Description for Pleth Variability Index (PVI) The pleth variability index (PVI) is a measure of the dynamic changes in the perfusion index
(PI) that occur during the respiratory cycle. The calculation is accomplished by measuring changes in PI over a time interval where one or more complete respiratory cycles have occurred. PVI is displayed as a percentage (0-100%). The utility of PVI is unknown at this time and requires further clinical studies. Technical factors that may affect PVI include probe malposition and patient motion. rainbow Pulse CO-Oximetry Technology rainbow Pulse CO-Oximetry technology is governed by the following principles:
1. Oxyhemoglobin (oxygenated blood), deoxyhemoglobin (non-oxygenated blood), carboxyhemoglobin (blood with carbon monoxide content), methemoglobin
(blood with oxidized hemoglobin) and blood plasma constituents differ in their absorption of visible and infrared light (using spectrophotometry). The amount of arterial blood in tissue changes with pulse
(photoplethysmography). Therefore, the amount of light absorbed by the varying quantities of arterial blood changes as well. 2. www.masimo.com 25 Masimo Radical-7 Chapter 1: Technology Overview The Radical-7 uses a multi-wavelength sensor to distinguish between oxygenated blood, deoxygenated blood, blood with carbon monoxide, oxidized blood and blood plasma. The Radical-7 utilizes a sensor with various light-emitting diodes (LEDs) that pass light through the site to a diode (detector). Signal data is obtained by passing various visible and infrared lights (LEDs, 500 to 1400nm) through a capillary bed (for example, a fingertip, a hand, a foot) and measuring changes in light absorption during the blood pulsatile cycle. This information may be useful to clinicians. The maximum radiant power of the strongest light is rated at 25 mW. The detector receives the light, converts it into an electronic signal and sends it to the Radical-7 for calculation. 1. Light Emitting Diodes (LEDs)
(7 + wavelengths) 2. Detector Once the Radical-7 receives the signal from the sensor, it utilizes proprietary algorithms to calculate the patients functional oxygen saturation (SpO2 [%]), blood levels of carboxyhemoglobin (SpCO [%]), methemoglobin (SpMet [%]), total hemoglobin concentration
(SpHb [g/dL]) and pulse rate (PR). The SpCO, SpMet and SpHb measurements rely on a multi-wavelength calibration equation to quantify the percentage of carbon monoxide and methemoglobin and the concentration of total hemoglobin in arterial blood. In an ambient temperature of 35 C the maximum skin surface temperature has been measured at less than 106 F (41 C), verified by Masimo sensor skin temperature test procedure. Pulse CO-Oximetry vs. Drawn Whole Blood Measurements When SpO2, SpCO, SpMet, and SpHb measurements obtained from the Radical-7
(noninvasive) are compared to drawn whole blood (invasive) measurements by blood gas and/or laboratory CO-Oximetry methods, caution should be taken when evaluating and interpreting the results. The blood gas and/or laboratory CO-Oximetry measurements may differ from the SpO2, SpCO, SpMet, SpHb, and SpOC measurements of the Radical-7. Any comparisons should be simultaneous, meaning the measurement on the device should be noted at the exact time that blood is drawn. In the case of SpO2, different results are usually obtained from the arterial blood gas sample if the calculated measurement is not appropriately corrected for the effects of variables that shift the relationship between the partial pressure of oxygen (PO2) and saturation, such as:
pH,temperature, the partial pressure of carbon dioxide (PCO2), 2,3-DPG, and fetal hemoglobin. In the case of SpCO, different results are also expected if concentration of methemoglobin in the blood gas sample is abnormal (greater than 2% for methemoglobin concentration). High levels of bilirubin may cause erroneous SpO2, SpMet, SpCO, and SpHb readings. As blood samples are usually taken over a period of 20 seconds (the time it takes to draw the www.masimo.com 26 Masimo Radical-7 Chapter 1: Technology Overview blood) a meaningful comparison can only be achieved if the oxygen saturation, carboxyhemoglobin, and methemoglobin concentration of the patient are stable and not changing over the period of time that the blood gas sample is taken. Subsequently, blood gas and laboratory CO-Oximetry measurements of SpO2, SpCO, SpMet, SpHb, and SpOC may vary with the rapid administration of fluids and in procedures such as dialysis. Additionally, drawn whole blood testing can be affected by sample handling methods and time elapsed between blood draw and sample testing. Measurements with Low Signal IQ should not be compared to laboratory measurements. General Description for Total Hemoglobin (SpHb) Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of total hemoglobin (SpHb) in arterial blood. It relies on the same principles of pulse oximetry to make its SpHb measurement. The measurement is taken by a sensor capable of measuring SpHb, usually on the fingertip for adult and pediatric patients. The sensor connects directly to the Pulse CO-Oximeter or with a patient cable. The sensor collects signal data from the patient and sends it to the instrument. The instrument displays the calculated data as measurement of total hemoglobin concentration. Successful Monitoring for SpHb A stable SpHb reading is associated with correct sensor placement, small physiological changes during the measurement and acceptable levels of arterial perfusion at the measurement site. Physiological changes at the measurement site are mainly caused by fluctuations in the oxygen saturation, blood concentration and perfusion. See Safety Information, Warnings, and Cautions on page 11 and Troubleshooting Measurements on page 111. General Description for Total Arterial Oxygen Content (CaO2) Oxygen (O2) is carried in the blood in two forms, either dissolved in plasma or combined with hemoglobin. The amount of oxygen in the arterial blood is termed the oxygen content (CaO2) and is measured in units of ml O2/dL blood. One gram of hemoglobin (Hb) can carry 1.34 ml of oxygen, whereas 100 ml of blood plasma may carry approximately 0.3 ml of oxygen*. The oxygen content is determined mathematically as:
CaO2 = 1.34 (ml O2/g Hb) x Hb (g/dL) x HbO2 + PaO2 (mm Hg) x (0.3 ml O2/100 mm Hg/dL) Where HbO2 is the fractional arterial oxygen saturation and PaO2 is the partial pressure of arterial oxygen. For typical PaO2 values, the second part of the above equation (PaO2 [mm Hg] x [0.3 ml O2/
100 mm Hg/dL]) is approximately 0.3 ml/dL. Furthermore, for typical carboxyhemoglobin and methemoglobin levels, the functional saturation (SpO2) as measured by a pulse oximeter is given by:
*Martin, Laurence. All You Really Need to Know to Interpret Arterial Blood Gases, Second Edition. New York: Lippincott Williams & Wilkins, 1999. SpO2 = 1.02 x HbO2 www.masimo.com 27 Masimo Radical-7 General Description for SpOC Chapter 1: Technology Overview The above approximations result in the following reduced equation for oxygen content via the Pulse CO-Oximeter:
SpOC (ml/dL*) = 1.31 (ml O2/g Hb) x SpHb (g/dL) x SpO2 + 0.3 ml/dL
*When ml O2/g Hb is multiplied by g/dL of SpHb, the gram unit in the denominator of ml/g cancels the gram unit in the numerator of g/dL resulting in ml/dL (ml of oxygen in one dL of blood) as the unit of measure for SpOC. See Safety Information, Warnings, and Cautions on page 11. General Description for Carboxyhemoglobin (SpCO) Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of carboxyhemoglobin concentration (SpCO) in arterial blood. It relies on the same basic principles of pulse oximetry (spectrophotometry) to make its SpCO measurement. The measurement is obtained by placing a sensor on a patient, usually on the fingertip for adults and the hand or foot for infants. The sensor connects either directly to the Pulse CO-Oximetry instrument or through an instrument patient cable. The sensor collects signal data from the patient and sends it to the instrument. The instrument displays the calculated data as percentage value for the SpCO, which reflect blood levels of carbon monoxide bound to hemoglobin. Successful Monitoring for SpCO A stable SpCO reading is associated with correct sensor placement, small physiological changes during the measurement and acceptable levels of arterial perfusion in the patients fingertip (measurement site). Physiological changes at the measurement site are mainly caused by fluctuations in the oxygen saturation, blood concentration and perfusion. General Description for Methemoglobin (SpMet) Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of methemoglobin concentration (SpMet) in arterial blood. It relies on the same basic principles of pulse oximetry (spectrophotometry) to make its SpMet measurement. The measurement is obtained by placing a sensor on a patient, usually on the fingertip for adults and the hand or foot for infants. The sensor connects either directly to the Pulse CO-Oximetry instrument or through a patient cable. The sensor collects signal data from the patient and sends it to the instrument. The instrument displays the calculated data as percentage value for the SpMet. www.masimo.com 28 Masimo Radical-7 Successful Monitoring for SpMet Chapter 1: Technology Overview A stable SpMet reading is associated with correct sensor placement, small physiological changes during the measurement and acceptable levels of arterial perfusion in the patients fingertip (measurement site). Physiological changes at the measurement site are mainly caused by fluctuations in the oxygen saturation, blood concentration and perfusion. See Safety Information, Warnings, and Cautions on page 11. SpCO, SpMet, and SpHb Measurements During Patient Motion The Radical-7 displays measurements of SpCO, SpMet, and SpHb during patient motion. However, because of the changes in the physiological parameters such as blood volume, arterial-venous coupling, etc. that occur during patient motion, the accuracy of such measurements may not be reliable during excessive motion. In this case, the measurement value for SpCO, SpMet, or SpHb displays as dashes (---) and a message (Low SpCO SIQ, Low SpMet SIQ, or Low SpHb SIQ) displays to alert the clinician that the instrument does not have confidence in the value due to poor signal quality caused by excessive motion or other signal interference. rainbow Acoustic Monitoring (RAM) Technology rainbow Acoustic Monitoring (RAM) continuously measures a patients respiration rate based on airflow sounds generated in the upper airway. The Acoustic Sensor translates airflow sounds generated in the upper airway to an electrical signal that can be processed to produce a respiration rate, measured as breaths per minute. Respiratory sounds include sounds related to respiration such as breath sounds (during inspiration and expiration), adventitious sounds, cough sounds, snoring sounds, sneezing sounds, and sounds from the respiratory muscles [1]. These respiratory sounds often have different characteristics depending on the location of recording [2] and they originate in the large airways where air velocity and air turbulence induce vibration in the airway wall. These vibrations are transmitted, for example, through the lung tissue, thoracic wall and trachea to the surface where they may be heard with the aid of a stethoscope, a microphone or more sophisticated devices. rainbow Acoustic Monitoring Architecture The following figure illustrates how a respiratory sound produced by a patient can be turned into a numerical measurement that corresponds to a respiratory parameter. Patient Sensor Acquisition System Respiratory airflow to sound Sound to electrical signal Electrical signal to digital signal www.masimo.com 29 Masimo Chapter 1: Technology Overview Envelope Detection RRa Estimation Radical-7 Signal Processing Digital signal to respiratory measurement Patient The generation of respiratory sounds is primarily related to turbulent respiratory airflow in upper airways. Sound pressure waves within the airway gas and airway wall motion contribute to the vibrations that reach the body surface and are recorded as respiratory sounds. Although the spectral shape of respiratory sounds varies widely from person to person, it is often reproducible within the same person, likely reflecting the strong influence of individual airway anatomy [2-6]. Sensor The sensor captures respiratory sounds (and other biological sounds) much like a microphone does. When subjected to a mechanical strain, (e.g., surface vibrations generated during breathing), the sensor becomes electrically polarized. The degree of polarization is proportional to the applied strain. The output of the sensor is an electric signal that includes a sound signal that is modulated by inspiratory and expiratory phases of the respiratory cycle. Acquisition System The acquisition system converts the electric signal provided by the sensor into a digital signal. This format allows the signal to be processed by a computing device. www.masimo.com 30 Masimo Radical-7 Signal Processing Chapter 1: Technology Overview The digital signal produced by the acquisition system is converted into a measurement that corresponds to the respiratory parameter of interest. As shown in the previous figure, this can be performed by, for example, determining the digital signal envelope or outline which in turn may be utilized to determine the respiratory rate. In this way, a real-time, continuous breath rate parameter can be obtained and displayed on a monitor which, in many cases, may be real-time and continuous. The respiratory cycle envelope signal processing principle is similar to methods that sample airway gasses and subsequently determine a respiratory rate.

See instructions for use provided with the Spacelabs monitor. See Device Related Safety Information, Warnings, and Cautions on page 14 and Serial Interface Specifications on page 122. 2. 3. 4. 5. www.masimo.com 43 Masimo Radical-7 Setting Up and Using SatShare Chapter 3: Setup Parameter values from the Radical-7 can be displayed on a multi-parameter monitor through the SatShare feature. The SatShare feature provides an ideal, simulated plethysmographic waveform that corresponds to the parameter values determined the by Radical-7. This waveform may be used to display these values on multi-parameter monitors through the multi-parameter oximetry sensor or input connector. It is recommended that the Radical-7 be positioned near the multi-parameter monitor, with the Radical-7 screen displaying the plethysmographic waveform and the parameter values. Refer to the instructions for use provided with the multi-parameter monitor. See Device Related Safety Information, Warnings, and Cautions on page 14. To set up for use with SatShare interface 1. 2. 3. 4. Select the SatShare cable that is appropriate for the multi-parameter monitor. For the latest list of available SatShare cables and validated instruments, see www.masimo.com. Connect the labeled end of the SatShare cable to the SatShare Cable connector on the Docking Station. See Standalone Back Panel on page 39. For a secure connection, tighten the cable connector screws. Connect the other end of the SatShare cable to one of the following:
Verify that the Radical-7 recognizes the SatShare cable. If functional, the name of the SatShare cable displays on the Radical-7 screen. Sensor connector of the multi-parameter monitor cable Directly to the multi-parameter monitor 5. As appropriate, configure alarm limits on the multi-parameter monitor. 6. Set the averaging time for the multi-parameter monitor to its lowest setting (or fastest response). The ideal waveform for the Radical-7 requires additional averaging by the monitor. If the averaging time of the multi-parameter monitor is not changed, the time to display physiological changes in saturation on the monitor is increased with SatShare. However, the delay can be minimized by reducing the averaging time on the multi-parameter monitor. 7. While in the SatShare mode, if there are any significant discrepancies between the readings from Radical-7 and those on the monitor displaying the values obtained from SatShare, the values reported by the Radical-7 are to be considered the correct values. It is possible to use the Radical-7 with SatShare while the Radical-7 is not connected to AC power. However, in this configuration, battery run time is reduced. See Battery Operation and Maintenance on page 131. 8. 9. On the Radical-7, turn on the Satshare Numbers option. See Device Output on page 80. 10. If displaying the simulated waveform is not desirable, it is recommended to turn off the plethysmographic waveform display of the multi-parameter patient monitor.

Sensitivity Modes Overview Three sensitivity levels enable a clinician to tailor the response of the Radical-7 to the needs of the particular patient situation. Access the menu by touching on the indicator in the upper left corner of the Display View. The sensitivity levels are as follows:
NORM (Normal Sensitivity) NORM is the recommended sensitivity mode for patients who are experiencing some compromise in blood flow or perfusion. It is advisable for care areas where patients are observed frequently, such as an intensive care unit (ICU). APOD (Adaptive Probe Off Detection Sensitivity) APOD is the recommended sensitivity mode where there is a high probability of the sensor becoming detached. It is also the suggested mode for care areas where patients are not visually monitored continuously. This mode delivers enhanced protection against erroneous pulse rate and arterial oxygen saturation readings when a sensor becomes inadvertently detached from a patient due to excessive movement. MAX (Maximum Sensitivity) MAX is recommended sensitivity mode for patients with low perfusion or when a low perfusion message displays in APOD or NORM mode. MAX mode is not recommended for care areas where patients are not monitored visually, such as general wards. It is designed to interpret and display data at the measuring site when the signal may be weak due to decreased perfusion. When a sensor becomes detached from a patient, it will have compromised protection against erroneous pulse rate and arterial saturation readings. www.masimo.com 55 Masimo Radical-7 Changing Sensitivity Modes Chapter 4: Operation There are two ways to change the sensitivity modes. 1. Press the indication on the top left of the Display View. 2. Alternatively, from the Main Menu, touch the Profiles icon. From the Profiles screen, select the desired mode by scrolling up or down.

To remind clinicians that the feature is active, an offset value displays alongside the adjusted parameter value. When the In Vivo Adjustment is set to On, the feature is active (turned on) and a positive or a negative offset value appears, as shown in the following illustration. The In Vivo offset is set to zero for any of the following:
Cable or sensor is disconnect from instrument. Sensor goes off patient causing a sensor initialization to occur. Eight hours has elapsed since the In Vivo value was activated. Restore of factory defaults. The user turns off In Vivo. Offset value The offset value appears and indicates that In Vivo Adjustment is active. A positive value means that the value is increased (according to a laboratory reference value as entered by a clinician) and a negative value means the value is decreased (according to a laboratory reference value as entered by a clinician). In the example below, the SpO2 value is offset (highlighted) by -1.0 and SpHb is offset by
+0.4. The In Vivo Adjustment feature can be set to On or Off. the factory default setting is Off. If set to On, the parameter value is adjusted and an offset value appears. The offset value is set by the user. The feature applies to any of the following parameters:

Neonatal Displays in the Status bar as NEO and the color of the Profile button turns pink. Custom Displays in the Status bar as CUSTOM and the Profile button is not illuminated and appears gray. If no changes are made to settings, then after a power cycle, the Radical-7 automatically resets to the Adult profile because Adult is the factory default profile. If the Profile setting is changed to NEO or CUSTOM, then after a power cycle, the Radical-7 remembers the previously selected Profile setting. The active profile displays in the Status Bar. In the following example, the Adult profile is active. www.masimo.com 93 Masimo Radical-7 Chapter 5: Profiles The Radical-7 conveys the active profile by changing the color of the Profiles button. To restore all Radical-7 settings to factory default settings, see Access Control on page 76. Changing Profiles Changing Profiles is done in the Profiles Settings screen. There are different ways to access the Profiles Settings screen. The first way is by the touching the Profiles shortcut in the Status Bar, as show below.

To confirm the shutdown process, the following screen appears. www.masimo.com 98 Masimo Chapter 6: Alarms and Messages The following chapter contains information about alarms and messages. For more information, see Chapter 7: Troubleshooting on page 111. About Alarms The Radical-7 visually and audibly indicates alarm conditions that the system detects. Audible alarms may be silenced, without affecting the operation of visual alarms. See Safety Information, Warnings, and Cautions on page 11 and Alarm Related Safety Information, Warnings, and Cautions on page 20. There are three priorities for alarms:
High Medium Low Alarm Delay When an alarm condition is met, this feature delays the audible part of an alarm. Silencing the Alarms Alarms are conveyed in ways: audible, visual, or both. The following is an example of a visual alarm for an exception message:
www.masimo.com 99 Masimo Radical-7 Chapter 6: Alarms and Messages The following is an example of a typical alarm due to parameter limit violation. To silence or dismiss alarms:
Touch Silence (the highlighted area of the Status Bar). Audible alarms can be temporarily suspended by pressing the Alarm Silence button. When alarms are in the suspend state, pressing the Alarm Silence button cancels the alarm suspend. To silence audible alarms 1. When an audible is active, push Alarm Silence one time. 2. 3. The audible alarm is silenced for up to 120 seconds and a countdown timer displays. The length of time for which an audible alarm remains silenced (suspended) can be changed using the Silence Duration feature located on the Sounds screen. See Sounds on page 74. www.masimo.com 100 Masimo Radical-7 Chapter 6: Alarms and Messages Adaptive Threshold Alarm (ATA) Feature The Adaptive Threshold Alarm (ATA) feature is an optional feature that provides continuous SpO2 surveillance while allowing the clinician a useful tool to help reduce the frequency of audible alarms. ATA establishes the alarm limit threshold based upon the patient-specific baseline value of the SpO2 parameter which is determined from the recent history of SpO2 values. An Adaptive Threshold Limit is continuously determined for the patient and SpO2 values outside the Adaptive Threshold Limit trigger an audible alarm. The Adaptive Threshold Limit is bound by the standard SpO2 low alarm limit and the Rapid Desat low alarm limit. SpO2 values that exceed the Rapid Desat limit, whether it occurs rapidly or not, will activate an audible alarm. Prior to activating ATA, please review and select the appropriate standard low alarm limit and other alarm settings. Once ATA is selected, the Rapid Desat Alarm protection is always active. If the ATA low alarm limit is violated, ATA generates an audible alarm. It is important to note that once activated, ATA has the following automatic safety features:
Reminder Tones If an SpO2 value from a patient drops below the standard low alarm limit set by the user, a visual alert will display and a reminder tone will repeat every 15 minutes as long as the condition persists. If the SpO2 value drops below the ATA low alarm limit, an audible alarm will be activated. Rapid Desat Alarm Protection The Rapid Desat feature is always active when ATA is turned on. This means that deep desaturations (5% or 10%) from the standard SpO2 low alarm limit immediately generate an audible alarm. When used with ATA, it also serves as absolute low alarm limit protection. SpO2 values exceeding the Rapid Desat low alarm limit, whether rapid or not, will activate an audible alarm. The user can change the Rapid Desat default setting from 5% to 10%. ATA does not allow a Rapid Desat default setting of 0%. When ATA is turned Off, the instrument uses the standard alarm limits and standard alarm delays. About Alarms on page 99. Alarms for SpO2 on page 62. www.masimo.com 101 Masimo Radical-7 3D Alarms Chapter 6: Alarms and Messages 3D Alarms include the Desat Index Alarm and the PI Delta Alarm. Desat Index Alarm Overview on page 102. Perfusion Index (PI) Delta Alarm Overview on page 103. Desat Index Alarm Overview The Desat Index Alarm is a user-selectable feature which allows a clinician to request an audible and visual alarm if a patient experiences a specified number of desaturations over a specific period of time. Traditional high and low SpO2 alarm limits alert clinicians to saturation levels that exceed user selected thresholds, and these thresholds are typically established at a considerable change from the patients baseline saturation level. However, in select patient populations, substantial desaturation events that exceed a typical low alarm limit threshold may be preceded by a cycle of transient desaturations over a limited timeframe, and the ability to alert clinicians to a cycle of these smaller desaturations may provide an earlier indication of a potential significant decline in the patients status and the need for more focused monitoring and/or a change in treatment. To address patient populations at risk for cyclic, moderate desaturations, the option includes a user-selectable Desat Index Alarm which allows the clinician to request an audible and visual alarm in the event the patient experiences a specified number of desaturations beyond a defined level from the patients baseline saturation over a specific window of time, with each of these variables selectable by the user within established ranges as noted in Desat Index Settings on page 102.

The PI Delta Alarm is a user-selectable feature which allows a clinician to request an audible and visual alarm if perfusion at the monitored site decreases by a specified level (delta) over a specific period of time. Perfusion Index gives an indication of the level of perfusion at the monitored site. The Radical-7 measures perfusion at the SpO2 site by comparing the pulsatile signal to the non-pulsatile signal, and expressing that ratio as a percentage. PI has been clinically proven to be useful as a predictor of the level of illness in neonates and adults and that PI may change dramatically in response to sympathetic changes caused by inhalational agents and pain stimulation*. If PI decreases over time, there may be underlying physiological reasons that may need to be addressed. The PI Delta provides an audible and visual alert to important changes in perfusion compared to the patients baseline PI rate. The baseline is set by the Radical-7 once the user has enabled the alarm. The baseline is 30 seconds of currently averaged PI. The feature includes a user-selectable PI Delta Alarm. This allows the clinician to request an audible and visual alarm if perfusion at the monitored site decreases by a specified level (delta) over a specified window of time. Three of the variables are selectable by the user within established ranges as noted in PI Delta Settings on page 103.

Troubleshooting Measurements See Parameter Related Safety Information, Warnings, and Cautions on page 11. Signal IQ (SIQ) The Signal IQ provides an indicator of the assessment of the confidence in the displayed SpO2 value. The SpO2 SIQ can be also used to identify the occurrence of a patients pulse. With motion, the plethysmographic waveform is often distorted and may be obscured by artifact. Shown as a vertical line, the SpO2 SIQ coincides with the peak of an arterial pulsation. Even with a plethysmographic waveform obscured by artifact, the Signal IQ identifies the timing that the algorithms have determined for the arterial pulsation. The pulse tone (when enabled) coincides with the vertical line of the SpO2 SIQ. The height of the vertical line of the SpO2 SIQ provides an assessment of the confidence in the measurement displayed. A high vertical bar indicates higher confidence in the measurement. A small vertical bar indicates lower confidence in the displayed measurement. When the Signal IQ is very low, this suggests that the accuracy of the displayed measurement may be compromised. See About the Status Bar on page 49. When parameters are dimly lit, proceed with caution and do the following:
Assess the patient. Check the sensor and ensure proper sensor application. The sensor must be well secured to the site for the Radical-7 Pulse CO-Oximeter to maintain accurate readings. Misalignment of the sensors emitter and detector can result in smaller signals and cause erroneous readings. Determine if an extreme change in the patients physiology and blood flow at the monitoring site occurred, (e.g. an inflated blood pressure cuff, a squeezing motion, sampling of an arterial blood specimen from the hand containing the pulse oximetry sensor, severe hypotension, peripheral vasoconstriction in response to hypothermia, medications, or an episode of Raynauds syndrome.) With neonates or infants, check that the peripheral blood flow to the sensor site is not interrupted. Interruption, for example, may occur while lifting or crossing their legs during a diaper change. After performing the above, if the parameter remains dimly lit frequently or continuously, obtaining an arterial blood specimen for CO-Oximetry analysis may be considered to verify the oxygen saturation value. See Parameter Related Safety Information, Warnings, and Cautions on page 11. www.masimo.com 111 Masimo Radical-7 Dimly Lit Parameters Chapter 7: Troubleshooting When the signal quality is very low, the accuracy of measurements may be compromised, the parameter may be dimly lit, and the parameter may display dashes instead of a numeric value. Low Perfusion It has been suggested that at extremely low perfusion levels, pulse oximeters can measure peripheral saturation, which may differ from central arterial saturation This "localized hypoxemia" may result from the metabolic demands of other tissues extracting oxygen proximal to the monitoring site under conditions of sustained peripheral hypoperfusion. This may occur even with a pulse rate that correlates with the ECG heart rate. Low Signal Quality Improper sensor type or application. Next steps: Excessive motion relative to perfusion. Sensor is damaged or not functioning. Check and see if blood flow to the site is restricted. Check the placement of the sensor. Reapply sensor or move to a different site. See Appendix: Best Practices for Comparisons to Reference Measurements on page 139. SpO2 Values Do Not Correlate With Clinical Assessment or Arterial Blood Gas Measurements Low perfusion or sensor displacement. Next steps: Check for error messages. See Chapter 6: Alarms and Messages on page 99. Check placement of sensor or if it is too tight. Reapply sensor or select a new site. Set to MAX sensitivity and confirm that the sensor is securely on the patient. See the directions for use provided with your sensor. Unexpected SpO2, SpCO, SpMet, or SpHb Reading Low SIQ or PI values. Next steps: Reposition sensor to site with strong SIQ and PI. Average readings taken from three different sites to improve accuracy. Submit blood sample for laboratory CO-Oximetry test for comparison. Inappropriate sensor size or sensor measurement location. Next steps:Verify proper sensor for patient size. Verify proper sensor site. See Appendix: Best Practices for Comparisons to Reference Measurements on page 139. www.masimo.com 112 Masimo Radical-7 Unexpectedly High SpCO Reading Chapter 7: Troubleshooting Possible elevated methemoglobin level. Next steps: Submit blood sample for laboratory CO-Oximetry test. See Appendix: Best Practices for Comparisons to Reference Measurements on page 139. Difficulty Obtaining a Reading Low battery/ not plugged into AC power supply. Next steps: Insert Handheld into Docking Station, verify Docking Station power cord plugged in and Docking Station power indicator light is illuminated.

Ensure cable runs flat over the top of the hand directly in the middle of the finger with no kinks or twists so the cable does not pull on the sensor. Cover sensor with Masimo-provided shielding to avoid light interference. www.masimo.com 140 Masimo Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements Secure sensor cable to patients arm with tape. Instruct subjects to remain still without any sensor movement. Connect sensor cable to device without pulling on sensor. Wait until SpHb measurement is stable (one minute) before recording SpHb values. Note any Low SIQ message that displays during measurement. Blood sampling and laboratory analysis:
Record site of blood draw. Document exact time blood withdrawn from patient. When taking blood sample from arterial line, remove adequate dead space to ensure blood sample is not diluted with solution to keep arterial line open. When IV line set-up includes stopcocks, ensure that no fluid is infused through the line from which you are taking the blood. Draw blood directly into the vacutainer, if possible. Mix blood carefully after filling the vacutainer by rotating it gently at least 10 times. (A rotation is one turn of the tube upside down and then right side up.) All blood samples must be analyzed on the same calibrated laboratory hematology analyzer (Coulter, Sysmex, or equivalent) to avoid variation induced by the use of multiple laboratory devices. www.masimo.com 141 Masimo Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements Best Practices Checklist for SpCO Comparisons Ensure SpCO device is powered on and connected to computer with automatic data capture. After venous blood draw, SpCO testing must be initiated within 30 seconds (COHb can change rapidly). Sensor site selection:
Remove anything from patient's arm that can impede blood flow to the sensor site, such as restrictive garments, accessories, purses, backpacks, watches, jewelry, and blood pressure cuff. Do not use sites with any of the following conditions:
An anatomically abnormal finger (e.g. damaged, clubbed, deviated, etc.). A finger or arm that has experienced previous surgical procedures. A finger or arm that is currently receiving an IV infusion. A finger or arm that currently used for blood pressure cuff. Site should be cleaned of debris and dry prior to testing. Nail polish should be removed prior to testing. Select the patients testing finger in the following priority:
Non-dominant ring or middle finger. Dominant ring or middle finger. Sensor selection:
Use the appropriate sensor as defined in the sensor directions for use. Ensure proper sensor positioning:
Rest patients hand and arm with sensor on a horizontal surface securely to limit the movement of the patient. Examine the finger while placed in the sensors to ensure the emitter and detector are directly aligned on top of each other and there is no gap between the sensor and fingertip. Align upper and lower red lines. If using a reusable sensor, make sure finger tip is inserted all the way and touching the finger stop inside the sensor (allowing long finger nails to extend beyond the finger stop). www.masimo.com 142 Masimo Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements Ensure cable runs flat over the top of the hand directly in the middle of the finger with no kinks or twists so the cable does not pull on the sensor. Cover sensor with Masimo-provided shielding to avoid light interference. Secure sensor cable to patients arm with tape. Instruct subjects to remain still without any sensor movement. Connect sensor cable to device without pulling on sensor. Wait until SpCO measurement is stable (one minute) before recording SpHb values. Note any Low SIQ messages that display during measurement. www.masimo.com 143 Masimo Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements Best Practices Checklist for Acoustic Respiration Rate Comparisons Acoustic Sensor placement The Acoustic sensor has a small black arrow on the front (item 1 in figure below), when placing the sensor the black arrow should point forward to the anterior of subjects body. Ensure placement site is hair-free, clean of debris, and dry prior to sensor placement. Use an alcohol swab to clean the neck area, if needed. The sensor pad (item 2 in the figure above) should be placed to either side of the larynx, in the area just above the thyroid cartilage and below the jaw line (see figure below). Ensure that there are no skin folds under the sensor pad. www.masimo.com 144 Masimo Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements For pediatric subjects that have limited neck space, the sensor may be placed on the right side of chest, underneath clavicle. The sensor should not be touching the clavicle. Place sensor tape on skin. Gently press on sensor tape from center outward so adhesive forms a good contact with patient's skin. Ensure there are no skin folds or air gaps under sensor pad. Remove the release liner from the anchor pad and place the anchor pad on patients side of the neck; route the sensor cable in front of patient. Do not place anchor pad on clothing. Pulse-Oximeter Sensor Placement Place finger sensor on middle or ring finger of hand opposite the blood pressure cuff. For reusable sensors, make sure the fingertip just touches the rubber stopper at the end of the sensor without going over it. Ensure sensor is right side up with the cable running in line with finger, not at an angle on dorsal (back side) of hand. Monitoring Ensure RRa device is turned on and connected to computer with automatic data capture. Connect sensor to cable. If RRa values are not displayed after 2 minutes or if the RRa value has dropped out, check the following:
Confirm appropriate sensor placement, orientation and site selections. Confirm that optical pulse-oximeter sensor is placed properly on the patient's finger. Confirm that all cables are plugged in at each of the various connection points and hubs. Auscultate with stethoscope to listen for air sounds on the side opposite sensor. If breath sounds are present, remove sensor and replace with new sensor on opposite side of neck. Change the sensor out if RRa value continues to not display. Verify that there is not excessive hair or a gap between the sensor and the neck and that it is placed. Simultaneously record the RRa and respiratory rates and from other methods. If comparing RRa to capnography respiration rate, a mask is recommended. Sidestream methods with a nasal cannula are not recommended because of dilution effect in the supplemental flow of gasses, inability to measure both nasal and oral airflow, and nasal cannula mispositioning. When recording values, confirm that there are no SIQ messages displayed on the device. Suggested directions to record manual respiration rate are as follows:
Use stethoscope to listen for breath sounds, count each breath cycle as one breathe, count for 60 seconds. Alternate method to stethoscope, count the number of chest rises/inhalations during a 60 second period. Record manual respiration rate to compare with RRa. www.masimo.com 145 Masimo Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements Adjust respiratory pause settings as necessary, default is 30 seconds (options are: 15, 20, 25, 30, 35, or 40 seconds). Document patient events and time of event (based on computer clock). Include events that may affect performance, these include:
Patient talking, picking at the sensor or nasal cannula, excessive movement, ambient noise present, fans or air blowing at sensor Inaccurate measurements may be caused by:
Excessive ambient or environmental noise (patient speaking, room noise) Improper sensor placement Cable disconnection Movement, picking, or air blowing at sensor www.masimo.com 146 Masimo Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements www.masimo.com 147 Masimo Index 3 3D Alarms 58, 102 A About 58, 91 About Alarms 99, 101 About Parameter Information 60, 62, 63, 65, 66, 69, 70, 71, 72, 73, 91, 102, 103 About the Display View 45, 48 About the Status Bar 48, 49, 79, 80, 111 About this Manual 7 About Trend Views 81 Access Control 46, 74, 75, 76, 94, 97 Accessing the Main Menu 47, 49, 57 Accuracy 115 Acoustic Waveform View 54 Acquisition System 30 Adaptive Threshold Alarm (ATA) Feature 62, 101 Additional Settings for PI 66 Additional Settings for PVI 70, 71 Additional Settings for RRa 69, 70 Additional Settings for RRp 67, 68 Additional Settings for SpHb 63, 64 Additional Settings for SpO2 62, 63 Alarm Limit Test 134 Alarm Related Safety Information, Warnings, and Cautions 20, 99 Alarms 119 Alarms for SpO2 62, 101, 134 Analog Output and Nurse Call Specifications 124 Analog Output Test 135 Appendix www.masimo.com Best Practices for Comparisons to Reference Measurements 112, 113, 139 B Battery 49, 75, 80 Battery Operation and Maintenance 36, 42, 44, 80, 114, 131, 133 Battery Run Time Significantly Reduced 114 Battery Test 135 Best Practices Checklist for Acoustic Respiration Rate Comparisons 144 Best Practices Checklist for Continuous SpHb Comparisons 139 Best Practices Checklist for SpCO Comparisons 142 Brightness 75, 80, 113, 132 Buttons Do Not Work When Pressed 114 C Changing Between Trend Views 82, 86 Changing Profiles 56, 58, 94 Changing Sensitivity Modes 56 Changing the Size of Parameter Values 35, 48, 50 Changing the Time Interval of Trend Data 85 Changing Trend Settings 88 Chapter 1 Technology Overview 23 Chapter 2 Radical-7 Descriptions 33 Chapter 3 Setup 41 Chapter 4 Operation 45 Chapter 5 Profiles 35, 45, 93 Chapter 6 Alarms and Messages 99, 112, 113 Chapter 7 149 Masimo Radical-7 Troubleshooting 99, 111 Chapter 8 Specifications 115 Chapter 9 Service and Maintenance 107, 131 Citations 129 Cleaning 131, 136 Compliance 121 Contacting Masimo 113, 114, 136 Continuous Speaker Tone 114 Contraindications 10 Country Codes (FCC and EU) 127 D Deleting Trend Data 90 Desat Index Alarm Overview 102, 103 Desat Index Alarms 102, 103 Desat Index Settings 102 Device Output 44, 75, 80, 135 Device Related Safety Information, Warnings, and Cautions 14, 42, 43, 44 Device Settings 57, 75, 106, 123 Difficulty Obtaining a Reading 113 Dimly Lit Parameters 112 Display Indicators 120 Docking Station Power Requirements 41 E Electrical 117 Electrical Safety Information, Warnings, and Cautions 18, 42 Environmental 41, 118 Estimated Run Times of Battery Power 132 Exclusions 137 F FastSat Overview 63 www.masimo.com Index Functional Oxygen Saturation 24 Functionality of the Radical-7 34 G General Description for Carboxyhemoglobin (SpCO) 28 General Description for Methemoglobin
