The sealing connection of other
parts of the patient circuit is
damaged.
Repair or replace the sealing
connection as per the procedures
described in section
5.3.2.4Adjust the
Regulator of the Pipeline Gas Supply
Inlet Assembly
.
There is water built up on the
measurement surface of O2
sensor.
Remove the built-up water and allow
the O2 sensor to air dry.
The O2 sensor is not calibrated.
Calibrate the O2 senser as per section
4.3.7O2 Sensor Calibration
(optional)
.
O2 concentration
measurement fails or
has great deviations.
The O2 sensor is damaged.
Replace the O2 sensor.
The airway pressure
gauge shows
inaccurate reading
or its pointer cannot
move.
The airway pressure gauge is
damaged.
Replace the airway pressure gauge.
The airway pressure
gauge does not
return to zero point.
The zero point of the airway
pressure gauge is abnormal.
Adjust the zero point of the airway
pressure gauge as per section
4.5Zero
the Airway Pressure Gauge
.
The flow sensor assembly is not
installed properly.
Re-install the flow sensor assembly.
There is water built up inside the
flow sensor assembly.
Remove the flow sensor assembly and
clear its inside water build-up.
The membrane of the flow
sensor assembly is distorted,
dirty or its inside resistance
changes. Zero drift occurs to the
pressure sensor of the electronic
flowmeter board.
Enter the user maintenance mode and
calibrate the flow sensor as per section
4.3.2Flow Calibration (factory)
.
The flow sensor is damaged.
Replace the flow sensor assembly.
The pressure sensor on the
electronic flowmeter board is
faulty.
Replace the electronic flowmeter
board.
The flow wave is
displayed abnormal.
The flow sensor pressure
sampling pipeline leaks.
Repair the flow sensor pressure
sampling pipeline after checking as
per the procedures described in section
5.3.4.1Leak Test of Flow Sensor
Pressure Sampling Pipeline
.
