breathe. If the patient breathes, the ventilator provides pressure support to the patient according to
the set pressure support level. The inspiration and expiration switch by the patient according to the
set expiratory trigger sensitivity. If there is no patient breathing within the set range of apnea
backup ventilation frequency, the ventilator provides pressure control ventilation according to the
set pressure support level, and the inspiratory and expiratory switches according to the set
expiratory trigger sensitivity and apnea backup ventilation frequency. The tidal volume depends on
the level of pressure support and the patient's inspiratory force.
PS/CPAP ventilation mode setup parameters:
Differential Pressure (△P)
Minimum frequency (FreqMIN)
Triggering sensitivity (Trigger)
Positive End-Expiratory Pressure (PEEP)
