The CO
2
modules is configured to compensate CO

readings for either Body Temperature
and Pressure, Saturated Gas (BTPS), to account for humidity in the patient’s breath, or
Ambient Temperature and Pressure, Dry Gas (ATPD).

To set the humidity compensation:
1. Select the CO
2
parameter area or waveform area to enter the [ CO2 Setup ] menu.
2. Select [
BTPS Compen

2
Module
A calibration should be performed once a year or when the readings go far beyond the range.
