The tidal volume of the mandatory breaths is
determined by the volume VT. The pressure rise is
determined by the flow acceleration FlowAcc. The
mandatory breaths are time-cycled and are not
triggered by the patient. The number of mandatory
breaths is determined by the respiratory rate RR.

If the flow acceleration is so high that the set tidal
volume is already reached before the set
inspiratory time T has fully elapsed, an inspiratory

pause occurs. The inspiratory pause can be
identified as the plateau P
Paw (t).
