Perform an SpO2 test
Use this procedure to test only the device SpO2 function.
1. Power on the device.
2. Connect the SpO2 functional simulator to the SpO2 input connector.
Note
3. Adjust the simulator settings as follows:
For Nonin and Nellcor configurations, set the simulator SpO2 saturation to 90% and
pulse rate to 60 bpm.
For Masimo configurations, set the simulator SpO2 saturation to 81% and pulse rate
to 60 bpm.
4. Give the device up to 30 seconds to stabilize.
5. Verify the displayed saturation and pulse rate as follows:
For Nonin and Nellcor configurations, saturation should be 90% ±1 sat point, and
pulse rate should be 60 ±1 bpm.
For Masimo configurations, saturation should be 81% ±3 sat point, and pulse rate
should be 60 ±1 bpm.
6. Disconnect the simulator.
