Pressure not maintained:
value
System was unable to maintain at least 25
cmH2O of pressure during relief valve check. 1. Verify breathing circuit is connected and not
leaking.
2. Verify low pressure vent engine 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.
Q1 = Value Intermediate value in low pressure leak check
compliance calculation. None, for information only.
Relief Pressure: Value
Safety Valve check:
Value
= back pressure
generated from 75 L/min flow thru open relief
valve. Must be less than 10 cmH
2
O to pass.
Refer to Section 7.1.4.
Relief Time: Value
Safety Valve check: Value = time required to
relieve pressure in system from 34 to less than
2 cmH
2
O. Must be less than 250 msec to pass.
Refer to Section 7.1.4.
Relief Valve Chk Relief valve check in progress. None
Relief Valve Chk Complete Relief valve check passed. None
Relief Valve Chk Fail Relief valve check failed. See previous message in status log for cause of
failure.
Rising Flow Not Achieved:
Value Could not achieve minimum flow required fro
step in Checkout.
Value =
maximum flow that was achieved
(mLpm)
1. Verify breathing circuit is connected and not
leaking.
2. Verify low pressure vent engine 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.
Sensor Disagree: Value During FCV calibration, if the Air (or O
2
) flow
sensor disagree by more than: 20% of total flow
or 1500 mL/min, whichever is greater, the
calibration will fail.
Value = flow difference
between Air (or O
2
) flow sensor and total flow
sensor.
1. Check regulator for oscillation.
2. If only one FCV cal fails, replace that flow
sensor.
3. If both FCV cal fail, replace total flow sensor.
Sensor Removed Exhalation flow sensor removed prior or during
checkout. Install exh flow sensor and rerun checkout.
Skipping CHECKOUT - not in
checkout state A Checkout command was received by the Vent
Control Board (VCB) while it was not in the
Checkout sate. This is most often caused by a
series of rapidly requested Checkout starts and
aborts without allowing Checkout to run in
between. Restart Checkout and allow it to allow it to
complete.
