D-7
Sensor failed. Or, great drift occurred to the flow sensor and
inspiratory valve. Use manual ventilation mode to help the
patient breathe. Calibrate the flow sensor and inspiratory
valve.
Calibrate PEEP
Valve L Last calibration of the Paw sensor and PEEP valve failed.
Or, great drift occurred to the Paw sensor and PEEP valve.
Use manual ventilation mode to help the patient breathe.
Calibrate the Paw sensor and PEEP valve.
Calibrate O2
Sensor L Last calibration of the O
2
sensor failed. Or, O
2
concentration was measured outside of the range. Check
that the reading on the O
2
sensor is 21%. Calibrate the O
2
sensor again or replace it.
O2 Sensor
Unconnected L The O
2
sensor was not connected to the cable or was not
connected properly. Make sure that the O
2
sensor is
correctly connected to the cable.
O2 Sensor Error M O2 sensor fault The measured O2 concentration is less
than 5%. Replace the O2 sensor.
Flow Sensor
Failure L Flow sensor monitoring failure. The equipment could
work but with low accuracy. Calibrate the flow sensor
again or replace it.
TV Comp Disabled L Tidal volume compensation was disabled. Calibrate the
flow sensor.
Pinsp Not Achieved L An error occurred to the breathing system or the ventilator
failed to supply the patient with required pressure. Check
the breathing system connections. Check the set values.
TV Not Achieved L The tidal volume was less than the set value for
consecutive six times. Look for leaks of the breathing
system. Make sure that sufficient tidal volume is supplied.
Check I:E, Plimit and TV set value.
Sensor Zero Failed L Automatic sensor zeroing failed. Zero the sensor manually
or restart the machine.
3-way Valve
Failure L 3-way valve connection or control failure. The machine
was operational but with unreliable monitoring. Use
manual ventilation mode to help the patient breathe when
necessary.
Heating Module
Failure L Thermistor or heating rod failure. Check the sensor for
vapor condensation.
IP Address Conflict M Set IP address again.
Mechanical
Ventilation Failure H Software reset abnormal. Restart the anesthesia machine.
If the problem persists, contact your service personnel.
