Technical Information
Equipment Response Time
If the SpO
2
signal from the sensor is inadequate, the last measured values
freeze for 10 seconds and are then replaced with dashes.
*Wireless communications can be delayed when in environments with high
radio interference.
Example – SpO
2
Exponential Averaging
SpO
2
decreases 1.0% every 2 seconds (5% over 10 seconds)
Pulse Rate = 75 BPM
Specific to this example:
• The response of the SpO
2
average is 6 seconds.
