MAINTENANCE
6. TESTING THE BREATH TIMEOUT ALARM (MEDIUM PRIORITY) AND
HIGH CIRCUIT PRESSURE ALARM (HIGH PRIORITY)
Begin by ventilating using the Low Activity button. Allow the ventilator to
ventilate for a few breaths using the current settings.
Using the
Clinician’s Settings
Menu, navigate to the
Low Activity
Prescription Setting Alarm Limits
and change the
BR
setting to 0/min.
Select
OK
and
CONFIRM
.
Wait up to 20 seconds to allow the Breath Timeout to trigger. The top of the
touch screen should display the Breath Timeout alarm (in yellow), and you
should hear a sequence of three tones indicating a medium-priority alarm or
vibrate.
NOTES:
•
The High Del. Pressure alarm may appear before the Breath Timeout
alarm.
•
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 for the Breath Timeout alarm, kink (try to impede air flow)
the
interface tubing near the connection to the ventilator.
Within a few seconds the top of the touch screen should display the High
Circuit Pressure (High Crct Pressure) alarm (in red), and you should hear a
sequence of two sets of five tones indicating a high priority alarm.
NOTE:
For a high-priority alarm, an audible tone immediately occurs with a
vibration alarm with no delay.
After verifying the correct alarm notifications for the High Circuit Pressure
alarm, release the interface tubing and allow the High Circuit Pressure alarm
to resolve itself.
Touch
OK
in the message that indicates the alarm has been resolved.
Using the
Clinician’s Settings
Menu, navigate to
Ventilation Settings
and
return the
BR
setting to 12/min. Select
OK
and
CONFIRM
.
The
Breath Timeout
alarm will resolve itself once the setting is changed.
