Meaning / Function
Switching spontaneous respiratory support on / off
Switching the synchronization on or off causes the following change to the venti-
lation mode:
Pressure-controlled
Sync. on PC - BIPAP
Sync. off PC - CMV
When synchronization is switched on, mandatory breaths are synchronized with
the patient's breathing 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
expiratory phase, an inspiratory trigger window is activated so that the manda-
tory 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 trig-
ger window, a premature mandatory breath is triggered.
If no spontaneous breathing is detected within the inspiratory trigger window, a
mandatory breath will be triggered immediately afterwards.
