If the inspiratory flow (Insp Flow) during
inspiratory effort is greater than the set trigger flow
(Trigger), the device supports the patient with the
setting ∆PPS.
The set inspiratory flow (Insp Flow) defines how
fast the ∆PPS pressure is reached. When 25 % of
the maximum inspiratory flow (Insp Flow) is
reached (or after maximum 4 seconds), the
inspiration is automatically ended. The value Freq
Min (e.g., 3 bpm (1/min)) defines a safety period
(safety period = 1/Freq Min, e.g., 20 seconds). If
no inspiratory effort is detected and the safety
period has elapsed, the device generates a
pressure-controlled breath with PINSP=∆PPS.
The lower alarm limit of the airway pressure PAW
low is used for the airway pressure monitoring to
detect apnea (disconnection) and continuous
pressure.
If the pressure waveform does not cross the
pressure threshold either from above or below, an
alarm is sounded.
