For the microstream CO
2
module, you can also set a period of time after which the CO
2
module enters the standby mode
if no breath is detected since the CO
2
module is powered on or the CO
2
module switches to the measuring mode or the
automatic standby time is re-set. To set the standby time, in the [
CO
2
Setup
] menu, select [
Auto Standby
] and then
select the appropriate setting.
15.3.3 Setting the CO
2
Unit
Select [
Unit Setup >>
] from the [
User Maintenance
] menu. In the popup menu, select [
CO
2
Unit
] and toggle between
[ mmHg ], [ % ] and [ kPa ].
15.3.4 Setting up Gas Compensations
WARNING

Make sure that the appropriate compensations are used. Inappropriate compensations may cause
inaccurate measurement values and result in misdiagnosis.
For the sidestream CO
2
module:
1. Select [
CO
2
Setup
].
2. According to the actual condition, set the concentration required for the following compensations:

[ O
2
Compen ]

[
N
2
O Compen
]

[
Des Compen
]
For the microstream CO
2
module, gas compensations are not required.
15.3.5 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).
1. ATPD:
100 / %) ( ) (
2 2 amb co
P vol CO mmHg P
× =
2. BTPS:
100 / ) 47 ( %) ( ) (
2 2
− × =
amb CO
P vol CO mmHg P
Where,
2 CO
P
= partial pressure,
% vol
= CO
2
concentration,
amb
P
= ambient pressure, and unit is mmHg.
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 [ CO2 Setup ] menu, select [ BTPS Compen ].
2. Select either [ On ] for BTPS or [ Off ] for ATPD, depending on which compensation applies.
