Settings
7.2.2.1 Set CO
2
Monitoring
When [Monitoring] is set to [ON], the CO
2
module enters operating mode. The ventilator
displays CO
2
parameters and waveform, and provides physiological alarms and technical
alarms related to CO
2
module. When [Monitoring] is set to [OFF], the CO
2
module enters
standby mode. The ventilator does not display CO
2
parameters and waveform, and not
provide physiological alarms related to CO
2
module either.
The standby mode of CO
2
module is relevant to the Standby status of ventilator:
If the ventilator enters Standby status, the CO
2
module also enters standby mode.
If the ventilator exits Standby status, the CO
2
module is restored to the CO
2
operating
mode before standby mode.
CO
2
module entering or exiting standby mode has no effect upon the ventilator.
To manually enter or exit standby mode, select the [Setup] key → [Sensor] → [CO
2
], and
set [Monitoring] to [OFF] or [ON].
In standby mode, the working components of the CO
2
module, such as gas pump and infrared
light source, are automatically turned off to extend the service life of the module.
7.2.2.2 Set Pump Rate
By selecting the [Setup] key → [Sensor] → [CO
2
], you can set the [Pump Rate] of the
sampling of patient gas. When patient type is Adult, you can set [Pump Rate] to [150]
mL/min, [120] mL/min, [100] mL/min, or [70] mL/min. When patient type is Pediatric, you
can set [Pump Rate] to [100] mL/min or [70] mL/min.
The pump rate tolerance: 15 % or 15 mL/min, whichever is greater.
Normally the operator shall clear the water inside the CO
2
watertrap at regular intervals. For
time interval to clear the watertrap, refer to section B.10.1Sidestream CO2 Module.
WARNING
Take the patient’s actual breathing volumes into consideration, and select the
appropriate pump rate for the patient.
Do not use a sidestream CO
2
module on the patient whose condition does not allow
to take 70 mL/min out of his total minute ventilation.
