– 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
determined by the patient. When no inspiratory
effort is detected, mechanical breaths are
delivered at the set minimum respiratory rate
RRmin and pressure support ∆Psupp.

Insp. term.
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 determined by the
patient category and the set minimum respiratory
rate RRmin.
Purely spontaneous breathing at CPAP level is
achieved by setting ∆Psupp=Off. In this case the
patient does not receive any more machine-
triggered breaths.
