[Calibration is successful]. Otherwise, it shows that the calibration failed, and it
needs to be recalibration at this time.
Notices：
Before oxygen concentration calibration, set 21% FiO2 and start the ventilation
for 1-3 minutes.
11.7 Flow sensor calibration
Calibration of flow sensor shall be carried out when error of flow monitoring value is
large or the flow sensor is replaced. Calibration of flow sensor can be performed
according to the following steps:
1. Connect respiratory line and flow sensor
2. After starting the machine, enter the calibration interface, firstly connect the
flow sensor reversely according to prompts on the interface, click the [Start]
key on right side of the [Flow sensor], then connect the flow sensor positively
according to prompts on the interface, and click the [Start] key on right side of
the [Flow sensor] again
3. If the calibration successes, the system will display a prompt message:
[Calibration is successful]. Otherwise, it shows that the calibration failed, and it
needs to be recalibration at this time.
11.8 Line compliance
Compliance calibration of the line shall be carried out when replacing the
respiratory line and the external accessories related to the connection between the
ventilator and respiratory line. Calibration of line compliance can be performed
according to the following steps:
1. Connect the respiratory line
2. After starting the machine, enter the calibration interface and insert the
Y-shaped connector into the leak detection plug according to the prompts on
the interface, so that the respiratory line is air-tight.
3. From the standby interface, select [System calibration] → [Line compliance] →
[Start] key
4. If the calibration successes, the system will display a prompt message:
[Calibration is successful]. Otherwise, it shows that the calibration failed, and it
needs to be recalibration at this time.
