CPAP / PSV
– Spontaneous breathing
– Spontaneous breathing with continuous positive pressure level with or without
pressure support
Each detected inspiratory effort at CPAP level induces a patient-triggered, flow-
controlled, and pressure-supported breath. Point in time, number, and duration of
pressure-supported breaths are controlled by the patient. When no inspiratory effort
is detected, mandatory breaths are delivered at the set minimum respiratory rate
RRmin and with pressure support ∆Psupp.
Patient-triggered breaths are ended as soon as the inspiratory flow falls below the
flow defined by the Insp term setting. The duration of a machine-triggered breath is
additionally defined by the patient category and the set minimum respiratory rate
RRmin.
Purely spontaneous breathing at CPAP level can be achieved by setting ∆Psupp to
Off. In this case, the patient does not receive any more pressure-supported breaths
and RRmin does not trigger any more mandatory breaths.
