CHECK
EXH VALVE
Obstruction or abnormal damage of the
exhalation valve. Clean or replace the exhalation valve and/or
its control tube.
Excessive moisture in the exhalation block.
Remove moisture from exhalation block and
valve.
Verify exhalation valve is seated properly.
Reduce temperature of the humidifier.
Defective connection or defective
exhalation valve tubing.
Reconnect the valve or replace the
exhalation valve and/or the exhalation valve
pilot pressure tube.
Defective inspiratory flow sensor. Have a qualified technician replace the
defective component(s) and call your
customer service representative.
CHECK EXH VALVE
PRESSURE
The exhalation valve may not be detected
by the ventilator when ventilation is started.
Or the exhalation valve may be falsely
detected when ventilation is started.
Restart ventilator to see if alarm clears. If
not, replace the ventilator and call your
customer service representative.
CHECK FIO
2
SENSOR
FIO
2
measured is less than 18%.
Check that FIO
2
sensor is properly
connected or
Recalibrate FIO
2
sensor or
Replace FIO
2
sensor.
CHECK PROXIMAL LINE1*
*IF PERSISTS
RESTART/SRVC
No connection of the proximal pressure
tube when ventilation starts.
Reconnect the proximal pressure line.
Proximal pressure line disconnected or
obstructed.
Reconnect the connection line or
replace it if obstructed.
Check for moisture or occlusion of the
proximal line.
Reduce humidifier temperature.
Switch to a heated wire circuit.
Defective proximal pressure sensor or
internal leak of the machine.
Restart ventilator to see if alarm clears. If
not,
have a qualified technician replace the
defective component(s) and call your
customer service representative.
CHECK REMOTE ALARM
Nurse Call or remote alarm system is
disconnected. Connect the Nurse Call or remote alarm
cable to the ventilator.
Relay control voltage problem.
Carefully monitor the patient to detect
possible alarm triggering and call for the
maintenance technician.
CHECK SETTINGS
Loss of memorised parameters.
Check and adjust the prescribed
parameters, if necessary.
Software versions have changed.
Check and adjust the prescribed
parameters, if necessary.
CONNECT VALVE
OR CHANGE PRESS
The ventilation settings are not compatible
with the type of patient circuit used.
No exhalation valve connected with PEEP
set to less than 4 mbar
or
PIP set to more than 30 mbar when relative
pressure is set to OFF.
Connect exhalation valve
Decrease PIP to less than 30 mbar in
absolute pressure.
Increase PEEP to more than 3 mbar.
Note:
Always consult the clinician before
changing PEEP, FIO
2
, pressure, volume or
Rate settings.
CONTROLLED CYCLES
The ventilator is delivering apnea ventilation
at set back up rate.
Check that the patient circuit is correctly
attached and the patient is correctly
ventilated.
