I
NSUFFICIENT PRESSURE SUPPORT ALARM
•
Is triggered if for 3 breaths in a row the maximum mask pressure achieved at
inspiratory to expiratory transition is either <87.5% of the absolute mask pressure
targetted at that point, or < absolute mask pressure targetted minus 1 cmH
whichever is the lower.
H
IGH LEAK ALARM
•
Leak exceeds 30 L/min for more than 20 seconds.
F
LOW BLOCKED ALARM
•
Flow is less than 6 L/min for more than 20 seconds.
