High Inspiratory
Pressure
Indicates that circuit pressure exceeds the high pressure
limit. When High Inspiratory Pressure condition occurs, the
ventilator immediately cycles into the exhalation phase and
illuminates the low priority indicator. Then on the second
consecutive breath with a pressure violation, sounds the
audible alarm, lights the Alarm High indicator, and displays
High Inspiratory Pressure message.
High Internal O

Oxygen concentration internal to the enclosure is beyond
allowable levels. Indicative of an internal O

leak. Alarm
cannot be silenced or manually reset.
High Leak Rate The average estimated leak from the previous breath has
exceeded the set High Leak alarm limit (alarm applies to
NPPV mode only). Medium urgency, escalates to high
urgency after 60 seconds. The alarm cancels when the
estimated leak from the previous breath equals or falls
below the alarm setting, if the ventilation type changes from
NPPV to another ventilation mode or if the alarm is reset by
the clinician.
