The tidal volume of the mandatory breaths is
determined by the volume VT. The duration of the
mandatory breaths is determined by T
pressure rise is determined by the flow acceleration
FlowAcc. If the inspiratory flow is so high that the
set tidal volume is already reached before the set
inspiratory time T has fully elapsed, an inspiratory
i
pause occurs.
MMV works similar to SIMV, however, the breaths
are only provided if spontaneous breathing is not
sufficient and below the prescribed minimum

ventilation. When spontaneous breathing
increases, fewer breaths will be provided. The
minimum ventilation is determined by the settings
of the tidal volume VT and the respiratory rate RR.
The maximum number of breaths is determined by
the respiratory rate RR. However, this number is
only provided when insufficient spontaneous
breathing is present.
