MAINTENANCE
1. TESTING THE HIGH GAS PRESSURE ALARM (MEDIUM PRIORITY)
Begin by ventilating using the Low Activity Button. Allow the ventilator to ventilate for a few breaths.
With the source gas supply on and connected to the ventilator and an adjustable regulator, set the regulator
to 95 PSI.
The top of the touch screen should display the High Gas Pressure alarm
(in yellow), and you should hear a sequence of three tones indicating a
medium-priority alarm or vibrate.
NOTES:
• If the Low PIP Pressure alarm is displayed before the High Gas Pressure
alarm, increase the volume in the
Ventilation Settings
until the Low PIP
Pressure alarm clears. Changes to the
Ventilation Settings
take effect
only after selecting the
OK
and
CONFIRM
buttons.
• If a low- or medium-priority alarm occurs while the ventilator is in
vibration mode, and the alarm is not resolved within 60 seconds, an
audible alarm occurs.
After verifying the correct alarm notifications, adjust the regulator to 50 PSI.
The
High Gas Pressure
alarm will resolve itself once the regulator has been adjusted to 50 PSI.
