O.
EPAP
during a timed breath is 5 cmH
2
O.
Timed breath rate is 15 BPM (timed breath indicator display).

Spontaneous breath test:
Occlude the test orifice for a few seconds. View the pressure
waveform, and create a small leak at the orifice to simulate a
spontaneous trigger (you might need to repeat this process a few
times).
Verify that the ventilator cycles to IPAP and that the Rate indicator
does not flash. Once a spontaneous breath is triggered, unblock the
test orifice.

Press
ALARMS
to go to the Alarms screen, then set
