Defibrillator/Monitor Operator’s Manual 14 - 5
14.6.5 Setting the Auto Standby Time
The equipment enters the standby mode automatically after the configured period of time if no breath is
detected since the last detected breath.
To set auto standby time:
1. Select the CO
2
parameter area to enter the [CO2 Setup] menu.
2. Select [Others >>].
3. Set [Auto Standby].
14.6.6 Setting the Apnea Alarm Delay
To set the apnea alarm delay:
1. Select the CO
2
parameter area to enter the [CO2 Setup] menu.
2. Set [Apnea Time]. The equipment gives an apnea alarm if the patient has stopped breathing for longer
than the preset apnea time.
14.6.7 Selecting Gas Compensations
• Make sure that the appropriate compensations are used. Inappropriate compensations may cause
inaccurate measurement values and result in misdiagnosis.
1. Select the CO
2
parameter area to enter the [CO2 Setup] menu.
2. Select [Others >>].
3. Respectively select:
â—† [O2 Compen]: 0 to 100%
â—† [N2O Compen]: 0 to 100%
â—† [AA Compen]: 0 to 24%
The sum of the three compensations should not be greater than 100%.
14.6.8 Setting Humidity Compensation
The CO
2
module is configured to compensate CO
2
reading for either Body Temperature and Pressure Saturated
(BTPS) gas, to account for humidity in the patient’s breath, or Ambient Temperature and Pressure Dry (ATPD) gas.
â– ATPD: P
CO2
(mmHg)=CO
2
(vol%) x P
amb
/100
â– BTPS: P
CO2
(mmHg)=CO
2
(vol%) x (P
amb
- 47)/100
Where, P
CO2
(mmHg)= partial pressure, vol%=CO
2
concentration, P
amb
=ambient pressure, and unit is mmHg.
You can set the humidity compensation on or off according to the actual condition.
To set the humidity compensation:
1. Select the CO
2
parameter area to enter the [CO2 Setup] menu.
2. Select [Others >>] → [BTPS Compensation].
3. Select either [On] for BTPS or [Off] for ATPD.
14.6.9 Barometric Pressure Compensation
The CO
2
module has the function of automatic barometric pressure compensation. That is to say, the system
automatically measures the barometric pressure which the equipment is exposed to.
