18.7.4 Entering the Standby Mode
You can set the CO
2
module to one of the following modes according to the module status:
■ Select
Measure
mode when you use the CO
2
module for monitoring.
■ Select
Standby
mode when you do not use the CO
2
module to prolong the serviec life of the CO
2
module.
The default operating mode is
Measure
. If you are not using the CO
2
module, you can proceed as follows to
enter the Standby mode:
1. Select the CO
2
numeric area or waveform area to enter the
CO2
menu.
2. Select the
Setup
tab.
3. Set
Operating Mode
to
Standby
.
18.7.5 Entering the Intubation Mode
When performing intubation during general anesthesia, you can enter the intubation mode in order to reduce
unnecessary alarms. To enter the intubation mode, follow this procedure:
1. Select the CO
2
numeric area or waveform area to enter the
CO2
menu.
2. Select
Intubation Mode
.
For the details of the intubation mode, see 9.13 Intubation Mode .
18.8 Changing Settings for Sidestream and Microstream CO
2
Module
18.8.1 Setting the Auto Standby
The monitor enters standby mode automatically after the configured period of time if no breath is detected
since the last detected breath. To set the auto standby, follow this procedure:
1. Select the CO
2
numeric area or waveform area to enter the
CO2
menu.
2. Select the
Setup
tab.
3. Set
Auto Standby
.
18.8.2 Setting 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).
■ ATPD:
P
CO2
(mmHg)=CO
2
(vol%) x P
amb
/100
■ BTPS (sidestream):
P
CO2
(mmHg)=CO
2
(vol%) x (P
amb
- 47)/100
■ BTPS (microstream):
P
CO2
(mmHg)=CO
2
(vol%) x (1- 0.03)x P
amb
/100
Where, P
CO2
(mmHg)= partial pressure, vol%=CO
2
concentration, P
amb
=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, follow this procedure:
1. Select the CO
2
numeric area or waveform area to enter the
CO2
menu.
2. Select the
Setup
tab.
3. Set
BTPS Compensation
.
◆
Switch on for BTPS.
◆
Switch off for ATPD.
