Minimum O 2 Delivery - Dräger Perseus A500 Instructions For Use Manual

Principles of operation
VC - CMV / AutoFlow
– Volume-controlled
– Pressure-limited
– Time-controlled
– Machine-triggered
– Decelerating inspiratory flow
The mandatory breaths are machine-triggered and
are not triggered by the patient.
VC - SIMV / AutoFlow
– Volume-controlled
– Pressure-limited
– Time-controlled
– Machine-triggered or patient-triggered

– Decelerating inspiratory flow
– Synchronized inspiration
In VC - SIMV / AutoFlow, the patient can breathe
spontaneously at any time, while the number of
mandatory breaths is predefined. When
synchronization is switched on, the breaths are
adapted to the spontaneous breathing efforts of
the patient. If spontaneous breathing effort by the
patient is detected during the inspiratory trigger
window, a patient-triggered breath will be initiated.
VC - SIMV / PS / AutoFlow
This mode is similar to VC - SIMV / AutoFlow,
except that the patient's spontaneous breathing at
the PEEP level during the expiratory phase is
pressure-supported with ∆Psupp when outside the
trigger window.
