Failure Description
Possible Cause
Recommended Action
[00000020] is
displayed
There is a zero point error for
the ventilator flow sensor.
1. Check the zero point of the sensor.
2. Check whether the inspiratory
valve is switched off: After the
inspiratory valve is switched off
(DA=0 on the valve diagnosis tool),
the AD value of the sensor on the
anesthesia machine does not change
(or the change is within 1%) when the
gas supply is connected and
disconnected. This indicates the valve
is switched off.
3. Replace the VCM.
[00000040] is
displayed
The measured range of the
inspiratory flow sensor is
abnormal.
1. Check whether the sampling line is
connected correctly.
2. Diagnose the failure using the valve
diagnosis tool: In the calibration
airway connection environment, start
the valve diagnosis tool. Seal the
expiratory valve with 4000 DA. Turn
on the inspiratory valve gradually, and
observe the measured values on the
calibration device when each valve is
switched on. If the measured value on
the calibration device close to (smaller
than) 90 L/min corresponds to a
sampling AD greater than 60000 on
the inspiratory flow sensor, the
measured range of the inspiratory
flow sensor is abnormal. In this case,
replace the inspiratory flow sensor.
3. Replace the VCM.
[00000080] is
displayed
The measured range of the
expiratory flow sensor is
abnormal.
1. Check whether the sampling line is
connected correctly.
2. Diagnose the failure using the valve
diagnosis tool: In the calibration
airway connection environment, start
the valve diagnosis tool. Seal the
expiratory valve with 4000 DA. Turn
on the inspiratory valve gradually, and
observe the measured values on the
calibration device when each valve is
switched on. If the measured value on
the calibration device close to (smaller
than) 90 L/min corresponds to a
sampling AD greater than 3900 on the
inspiratory flow sensor, the measured
range of the expiratory flow sensor is
abnormal. In this case, replace the
expiratory flow sensor.
3. Replace the VCM.
