The tidal volume of the mandatory breaths is deter-
mined by the volume VT. The duration of the man-
datory breaths is determined by Ti. The pressure
rise is determined by the Slope or Insp. flow set-
ting. The maximum pressure that Babylog VN500
uses is set via the Pmax therapy control. If Pmax is
not linked to the alarm limit Paw high, the pressure
can be limited using Paw high.

MMV works similar to SIMV, however, the manda-
tory breaths are only provided if spontaneous
breathing is not sufficient and below the prescribed
minimum ventilation. Should spontaneous breath-
ing increase, fewer mandatory breaths will be pro-
vided. The minimum ventilation is determined by
the setting of the tidal volume VT and the respirato-
ry rate RR.
