Principles of operation
16.2.4 Pressure-controlled ventilation
16.2.4.1 PC
16.2.4.2 PC - CMV
– Pressure-controlled
– Time-controlled
– Machine-triggered
The mandatory breaths are machine-triggered and are not triggered by the patient.
16.2.4.3 PC - SIMV
– Pressure-controlled
– Time-controlled
– Machine-triggered or patient-triggered
– Synchronized inspiration
In PC - SIMV, 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.
16.2.4.4 PC - SIMV / PS
This mode is similar to PC - SIMV, 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.
