Can’t Establish Pressure:
Flow
During Checkout step, unable to achieve 8 Lpm
with which to attempt to reach 34 cmH2O.
1. Verify breathing circuit is connected and not
leaking.
2. Verify low pressure vent engine system is not
leaking.
3. Verify exhalation valve is properly connected
and all seals are in place.
4. Verify gas flow from flow control valves. Recal
if necessary.
Can’t Extrapolate Table
During flow valve calibration, if a weak or
restricted gas supply pressure requires the 140
or 160 L/min points to be extrapolated and the
calculated value is > 65,000 DAC counts, this
message comes up. This results in maximum
flow limited to whatever is the highest flow point
in the calibration table.
Check for a weak or restricted gas supply
pressure.
Can’t Pressurize: Value
During Paw transducer check, the breathing
circuit could not reach 33 cmH
2
O.
During Relief Valve check, the breathing circuit
could not reach 30 cmH
2
O.
During Exh Valve Cal Check, the exp pressure
does not stabilize within 0.1 cmH
2
O within 12
seconds.
Value = max exp pressure achieved.
1. Verify breathing circuit is connected and not
leaking.
2. Verify low pressure vent engine system is not
leaking.
3. Verify exhalation valve is properly connected
and all seals are in place.
4. Verify gas flow from flow control valves. Recal
if necessary.
Can’t Pressurize1: Value
During 1st half of Low Pressure leak check, the
breathing circuit could not reach 34 cmH
2
O.
Value = max exp pressure achieved.
1. Verify breathing circuit is connected and not
leaking.
2. Verify low pressure vent engine system is not
leaking.
3. Verify exhalation valve is properly connected
and all seals are in place.
4. Verify gas flow from flow control valves. Recal
if necessary.
Can’t Pressurize2: Value
During 2nd half of Low Pressure leak check, the
breathing circuit could not reach 25 cmH2O.
Value = max exp pressure achieved.
1. Verify breathing circuit is connected and not
leaking.
2. Verify low pressure vent engine system is not
leaking.
3. Verify exhalation valve is properly connected
and all seals are in place.
4. Verify gas flow from flow control valves. Recal
if necessary.
Checking Supply Press1
During FCV calibration, the source and integrity
of the gas supply (compressor or wall supply) is
being tested.
None; normal operation.
