Low Insp Pressure If the peak airway pressure during any mandatory inhalation
is less than the Low Insp Pressure limit, the ventilator will
immediately signal a high priority alarm.
Note: If an inspiration is triggered immediately after the
mandatory minimum exhalation time of 200 msec, this
alarm will not be activated unless this condition occurs for
three consecutive breaths.
Low Minute Volume Indicates the measured patient minute ventilation (VE) is
below the set limit. It is elevated to high urgency after one
minute.
Note: A Low Minute Volume setting of zero (0) will disable
this alarm.

concentration is 18% or at least 6% below set value for 30
seconds. Verify operation of the O

sensor. Alarm cannot be
manually reset.
Low O

setting is above 21%. Check
O

Low PEEP If PEEP is less than the operator set Low PEEP limit for one
second during exhalation, triggers a medium priority alarm.
If the Low PEEP alarm remains active for one minute, the
alarm moves to high priority.

Note: If an inspiration is triggered immediately after the
mandatory minimum exhalation time of 200 msec, this
alarm will not be activated unless this condition occurs for
three consecutive breaths.

that the NPPV (mandatory or spontaneous breath) tidal
volume is less than the set limit. It is elevated to a high
urgency alarm after one minute.
Note: A Low Tidal Volume setting of zero (0) will disable this
alarm.
