16.3.4 Setting up Humidity Compensation
Sidestream and microstream CO
2
modules are configured to compensate CO
2
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).

unit is mmHg.
As the mainstream CO
2
module has a built-in heating component to prevent water vapor from
condensing, setting humidity compensation is not needed. For the sidestream and
microstream CO
2
module, you can set the humidity compensation on or off according to the
actual condition. To set the humidity compensation::
1. In the [CO
2
Setup] menu, select [Humidity Compen].
2. Select either [On] for BTPS or [Off] for ATPD, depending on which compensation
applies.
