Low Del. Pressure
Interface pressure during delivery
fails to exceed the minimum
expected.
Check the interface connections.
Check the interface; replace it if it is leaking.
Check that the interface is connected to the
ventilator, not the compressor.
Check the interface connections.
Check the interface; replace it if it is leaking.
Ensure the ventilator is properly docked into the
compressor.

Low Gas Pressure
NOTE:
Alarm may
appear on the screen
intermittently.
Gas pressure drops below the
allowable limit (35 PSI)
Check all connections for possible leak.
Ensure that the source gas supply hose is not
kinked or pinched.
Ensure you are using a 50-PSI (nominal) regulator
with a minimum outlet flow of ≥40 LPM at 41 PSI.
Ensure the gas source (e.g. cylinder) has a
sufficient supply of gas (e.g. check that the
cylinder is not empty.)
If using a cylinder as the gas source, ensure the
cylinder valve is fully open.
Connect the ventilator to the compressor in
Extended Range or Stationary Configuration or
connect the ventilator to another gas source
(oxygen cylinder or wall source).
If the alarm is not resolved, place the patient on an
alternate means of ventilation (if necessary) and
contact your service representative.
Verify that the compressor is powered on.
Check all connections for possible leak.
Ensure that the source gas supply hose is not kinked
or pinched.
Dock the ventilator back into the compressor.
If the alarm is not resolved, place the patient on
an alternate means of ventilation (if necessary),
or connect the ventilator to an alternate pressure
source (oxygen cylinder or wall source) in Stand-
Alone Configuration. Contact your service
representative.
The Low Gas Pressure alarm may temporarily sound
when switching from an Activity Button with a lower
volume to one with a higher volume, the alarm
should resolve itself within 60 seconds. Ventilation is
still provided while the ventilator is alarming.
The Low Gas Pressure alarm may temporarily sound
when switching from an Activity Button without PEEP
to one with PEEP. The alarm should resolve itself
within 60 seconds. Ventilation is still provided while
the ventilator is alarming.
A 50-foot source gas supply hose may require
changing to a 20-foot source gas supply hose, for
volumes greater than 350ml.
Verify that the compressor is powered on.
Ensure the ventilator is properly docked into the
compressor.
Ensure that the purge tube connector is not connected to
the compressor.
If the alarm is not resolved, place the patient on an alternate
means of ventilation (if necessary), or undock the ventilator
from the compressor and connect to an alternate pressure
source (oxygen cylinder or wall source) in Stand-Alone
Configuration. Contact your service representative.
The Low Gas Pressure alarm may temporarily sound when
switching from an Activity Button with a lower volume to one
