When you select Auto, the system automatically selects the RR source according to the priority. The priority of
RR source is first CO
2
, and then ECG. When the current RR source does not have valid measurement, the system
automatically switches the
RR Source to Auto.
16.8.4 Entering the Standby Mode
Set the CO
2
module to one of the following modes according to the module status:
■ Select Measure mode when using the CO
2
module for monitoring.
■ Select Standby mode to prolong the CO
2
module service life when not using the CO
2
module.
The default operating mode is
Measure. Whennot using the CO
2
module, proceed as follows to enter the
Standby mode:
1. Select the CO
2
numeric area or waveform area to enter the CO2 dialog.
2. Select the
Setup tab.
3. Set
Operating Mode to Standby.
16.8.5 Entering the Intubation Mode
When performing intubation during general anesthesia, enter the intubation mode 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 dialog.
2. Select
Intubation Mode.
For the details of the intubation mode, see
7.13Intubation Mode.
NOTE
• When the configured intubation period is over, the monitor automatically exits the intubation mode
and gives two alert sounds.
16.8.6 Setting the Auto Standby
The monitor enters standby mode automatically if no breath is detected after the configured period of time. To
set the auto standby, follow this procedure:
1. Select the CO
2
numeric area or waveform area to enter the CO2 dialog.
2. Select the
Setup tab.
3. Set
Auto Standby.
16.8.7 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, 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 dialog.
2. Select the
Setup tab.
3. Set
BTPS Compensation.
◆ Switch on for BTPS.
