Low Inspiratory Pressure Alarm
This is a high priority alarm. It is detected differently for volume and
pressure therapy modes.
For volume modes, the alarm will sound if the measured patient
pressure is less than the Low Inspiratory Pressure setting specified by
the clinician. The alarm will automatically terminate when the peak
pressure at the end of the breath is greater than or equal to the Low
Inspiratory Pressure alarm setting.
For pressure modes, the alarm occurs when the delivered pressure
is 5 cmH
2
O or more below the target patient pressure during the
inspiratory phase. The alarm will automatically terminate when
the delivered pressure comes within 5 cmH
2
O of the target patient
pressure during the expiratory phase.
High Minute Ventilation Alarm
This alarm is a high priority alarm. It occurs when the patient’s
minute ventilation is greater than the High Minute Ventilation alarm
setting. The device continues to operate. The alarm will automatically
terminate when the calculated minute ventilation is less than the
High Minute Ventilation alarm setting.
Low Minute Ventilation Alarm
This alarm is a high priority alarm. It when the patient’s minute
ventilation is less than the Low Minute Ventilation alarm setting. The
device continues to operate. The alarm will automatically terminate
when the calculated minute ventilation is greater than the Low
Minute Ventilation alarm setting.
Low Battery Alarm
The Low Battery alarm occurs when the last battery available is low or
nearly depleted. This alarm occurs in two stages. When approximately
20 minutes of battery run time remains, a medium priority alarm is
generated, and the device continues to operate. If no action is taken and
the battery continues to deplete, the alarm escalates to a high priority
alarm when approximately 10 minutes of battery run time remains.
WARNING
Immediately seek an alternate
power source when the “Low
Battery” message appears.
Complete power failure and loss
of therapy is imminent.
WARNING
The ventilator has a two-stage
low battery alarm. The medium
priority alarm indicates that
approximately 20 minutes of
operation remain, and the high
priority alarm indicates that less
than 10 minutes of operation
remain. Actual run time may be
more or less than this and varies
with battery age, environmental
conditions, and therapy.
