than 24 hours have passed since
the last flow sensor calibration.
Calibration failure or measured
O2 is greater than 110%.
Patient volume mismatch
occurred during the last case.
Air pipeline pressure is invalid.
Hardware failure.
O pipeline pressure is invalid.
2
Transducer failure.
Breaths detected in circle circuit
while non-circle 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 TVinsp for at least 30
seconds.
Setting on Alarm Setup menu.
Power supply temperature
exceeds 75°C.

7 Alarms and Troubleshooting
Action
Calibrate the flow sensors.
Calibrate the O2 cell. Replace the O2 cell if
necessary.
Calibrate, dry or replace the flow sensors.
Start a new case.
Check pipeline supply pressure.
Contact a Datex-Ohmeda trained service
representative.
Contact a Datex-Ohmeda trained service
representative.
Check pipeline supply pressure.
Contact a Datex-Ohmeda trained service
representative.
Check circle circuit connections and settings.
Check that the water trap is properly attached
to the airway module.
Ensure the internal 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.
Vent TVexp is less than 50% of vent TVinsp
for at least 30 seconds. Message indicates
that the Leak Audio alarm is turned off.
Shut down system as soon as possible.
Then, check cooling fans and filters.
