An LED in the oximeter emits light rays through the body, wherever the probe is used, e.g. through the finger, at two different specific wavelengths. Each of these is selectively absorbed by oxygenated hemoglobin and deoxyhemoglobin in the blood. An optical receptor measures the changes in the light intensity after the light passes through the capillary network and estimates the ratio of oxygenated hemoglobin and the total hemoglobin. 5.2 Safety Information Warning:
cautions. Only use the SpO 2 probes specified in this manual. Follow the SpO2 probe instructions for use and adhere to all warnings and When a trend toward patient deoxygenation is indicated, blood samples should be analyzed by a laboratory co-oximeter for a full diagnosis of the patients condition. 23 AH-TX Series Handheld Pulse Oximeter Instruction Manual Do not use the oximeter and the SpO 2 probe during magnetic resonance imaging (MRI). The induced current could cause burns to the patient. Prolonged continuous monitoring may increase the risk of unexpected changes in skin characteristics of the patient, such as irritation, reddening, blistering or burns. Inspect the probe site every two hours and move the probe if the skin quality changes. For neonates, or patients with poor peripheral blood circulation or sensitive skin, inspect the probe site more frequently. Check the SpO 2 probe and its package for any sign of damage before use. Do not use the probe if any damage is detected. When discarding a disposable or broken SpO 2 probe, please observe all local, state, and federal regulations relating to the disposal of this products or similar products. If using a disposable probe, do not reuse it on different patients. Caution: In cases where it is necessary to add a clip to fix the fingertip probe, clip the cable and not the probe itself. Please note that the probe cable should not be pulled with force. Note:
The pleth wave is not equal to the intensity of PR signal. The oximeter does not provide an automatic self-check alarm signal; the operator should use an SpO2 simulator or use the oximeter on themselves to check the oximeter is working correctly. 24 AH-TX Series Handheld Pulse Oximeter Instruction Manual 5.3 Monitoring Procedure 1. Selecting the SpO2 Probe Depending on the patient category, weight and application site, you can select a different SpO2 probe as required. 2. Connecting the SpO2 Probe Plug the SpO2 probe cable into the SpO2 connector on the oximeter. 3. Applying the SpO2 Probe to the patient Clean the application site, removing barriers such as colored nail polish, and apply the probe to the patient. Warning:
inflation. Do not use the SpO2 c on a limb where a NIBP cuff has been applied. This may result in inaccurate SpO 2 readings during cuff Do not attempt to monitor SpO 2 levels on a finger that has been painted with nail polish, as this may result in unreliable measurements. 5.4 Parameter Display 25 AH-TX Series Handheld Pulse Oximeter Instruction Manual Fig 5-1 Parameter and PPG Waveform 1.
