Cause
No spontaneous breaths in set period
of time (Backup Time) since starting
™
PSVPro
mode.
The breathing system is not latched.
Flow sensor calibration failure.
Calibration failure or measured O2 is
greater than 110%.
Patient volume mismatch occurred
during the last case.
On/Standby button is pushed during a
patient case.
Air pipeline pressure is invalid.
O2 pipeline pressure is invalid.
N2O pipeline pressure is invalid.
Breaths detected in the circle circuit
while non-circuit is selected.
Water trap not attached.
System has detected an improper flow
pattern in the breathing circuit.
Possible blockage in airway module
sample gas outlet.
Vent TVexp is less than half of vent TV
insp for at least 30 seconds.
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.
Power supply temperature exceeds 75
degrees C.
Fan reporting error.
Action
Select a new ventilation mode. The
number of consecutive patient triggered
breaths reaches the Exit Backup
setting.
Lift the lower breathing system and
ensure it latches. Close breathing
system door.
Calibrate the flow sensors.
Calibrate the O2 cell. Replace O2 cell if
calibration fails.
Calibrate, dry or replace the flow
sensors. Start a new 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.
Check pipeline supply pressure.
Check pipeline supply pressure.
Check pipeline supply pressure.
Check circle circuit connections and
settings.
Check that the water trap is properly
attached to the airway module.
Ensure the flow sensors are connected
correctly.
Check for blockage in the airway
module sample gas outlet. Remove
blockage.
Check for leaks in the patient circuit.
Calibrate flow sensors. If problem
persists, replace flow sensors.
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.
Shut down system as soon as possible.
Then, check cooling fans and filters.
