Message Priority Cause Action
Backup Mode
active Low No spontaneous breaths in set period
of time (Backup Time) since starting
PSVPro
™
mode.
Select a new ventilation mode. The
number of consecutive patient triggered
breaths reaches the Exit Backup
setting.
Breathing system
loose Low The breathing system is not latched. Lift the lower breathing system and
ensure it latches. Close breathing
system door.
Calibrate
(remove) flow
sensors Low Flow sensor calibration failure. Calibrate the flow sensors.
Calibrate O2
sensor Low Calibration failure or measured O2 is
greater than 110%. Calibrate the O2 cell. Replace O2 cell if
calibration fails.
Calibrate, dry, or
replace flow
sensors Low Patient volume mismatch occurred
during the last case. Calibrate, dry or replace the flow
sensors. Start a new case.
Confirm to
shutdown High On/Standby button is pushed during a
patient case. Select Confirm within 10 seconds and
the system will shut down. If Confirm is
not selected within 10 seconds, the
system reverts to the screen showing
before the On/Standby button was
pushed.
Cannot monitor
Air pipeline Medium Air pipeline pressure is invalid. Check pipeline supply pressure.
Cannot monitor
O2 pipeline Medium O2 pipeline pressure is invalid. Check pipeline supply pressure.
Cannot monitor
N2O pipeline Medium N2O pipeline pressure is invalid. Check pipeline supply pressure.
Check circuit
connections Medium Breaths detected in the circle circuit
while non-circuit is selected. Check circle circuit connections and
settings.
Check D-Fend Medium Water trap not attached. Check that the water trap is properly
attached to the airway module.
Check flow
sensors Medium System has detected an improper flow
pattern in the breathing circuit. Ensure the flow sensors are connected
correctly.
Check sample
gas out Medium Possible blockage in airway module
sample gas outlet. Check for blockage in the airway
module sample gas outlet. Remove
blockage.
Circuit leak Medium Vent TVexp is less than half of vent TV
insp for at least 30 seconds. Check for leaks in the patient circuit.
Calibrate flow sensors. If problem
persists, replace flow sensors.
Circuit leak
silenced Low Setting on Alarm Setup menu. Vent
TVexp is less than 50% of vent TVinsp
for at least 30 seconds and Leak Audio
is changed from On to Off. Check the patient. Make sure Leak
Audio Off is the appropriate setting for
the case. Check for leaks in the patient
circuit. Calibrate flow sensors. If
problem persists, replace flow sensors.
Circuitry > 75C.
Shutdown
possible. Medium Power supply temperature exceeds 75
degrees C. Shut down system as soon as possible.
Then, check cooling fans and filters.
Cooling fan
needs service.
System OK. Medium Fan reporting error. Shut down system as soon as possible.
Then, check cooling fans and filters.
