SIMV/CMV Switching spontaneous respiratory support on / off
Switching the synchronization on or off causes the following change to the ventila-
tion mode:
SIMV
CMV
When synchronization is switched on, mandatory breaths are synchronized with
the patient's inspiratory effort. In doing so, the respiratory rate RR is held constant
by adapting the mandatory breaths and the expiratory time. At the end of the expi-
ratory phase, an inspiratory trigger window is activated so that the mandatory
breath can be initiated prematurely by up to 5 seconds (patient category Adult) or
1.5 seconds (patient categories Ped and Neo). If the spontaneous inspiratory flow
reaches the set value of the flow trigger Trigger during this trigger window, a pre-
mature mandatory breath is triggered.
If no spontaneous breathing is detected within the inspiratory trigger window, a
mandatory breath will be triggered immediately afterwards.
