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.
