5-6 TM80 Telemetry Monitor Service Manual
5.4.3 SpO
2
Test
Tool required:
None
Follow this procedure to perform the test:
1. Connect an adult SpO
2
sensor to the SpO
2
connector of the TM80.
2. In the main menu, select Patient Info and set Patient Category to Adult on
the TM80.
3. Measure SpO
2
on your finger. (Assume that you stay healthy)
4. Check the Pleth wave and PR reading on the screen and make sure that the
displayedSpO
2
is within 95%-100%.
5. Remove the SpO
2
sensor from your finger and make sure that an alarm of
SpO
2
SensorOff is triggered.
Measurement accuracy verification:
The SpO
2
accuracy has been verified in human experiments by comparing with
arterial blood sample reference measured with a CO-oximeter. Pulse oximeter
measurements are statistically distributed and about two-thirds of the
measurements are expected to come within the specified accuracy range compared
to CO-oximeter measurements.
NOTE
A functional tester cannot be used to assess the accuracy of a pulse
oximeter monitor. However, it canbe used to demonstrate that a
particular pulse oximeter monitor reproduces a calibration curve
that hasbeen independently demonstrated to fulfill a particular
accuracy specification.
