Technical Information
Equipment Response Time
If the signal from the sensor is inadequate, the last measured SpO
2
and pulse rate values freeze
for 10 seconds and are then replaced with dashes.
Example - SpO

Exponential Averaging
SpO
2
decreases 0.75% per second (7.5% over 10 seconds)
Pulse Rate = 75 BPM
Specific to this example:
• The response of the 4-beat average is 1.5 seconds.
• The response of the 8-beat average is 3 seconds.
