Operation
Synchronized volume guaranteed ventilation
with pressure support (optional)
Pressure support is activated during Volume AF by
entering a value for the level of pressure support.
This can be defined via the soft key
sync.

1 Press the soft key
tivated, the last value set for pressure support
appears as the default value, together with the
last value set for the trigger sensitivity above it.
2 Set and confirm the value for pressure support
with the rotary knob. When finally confirmed,
the indication PressSupp in the status area (G)
of the ventilation mode lights up steadily instead
of flashing.
If the patient was ventilated without synchronization
when pressure support was activated, synchroniza-
tion will be activated automatically with the last trig-
ger setting used.
Synchronization is maintained with the set value
when pressure support is deactivated and set to
OFF.
In case of a continuous and strong patient activity,
it is possible that the mandatory ventilation coin-
cides with the pressure supported patient breaths,
resulting in an increased tidal volume V
Pressure support is automatically deactivated
when the trigger is deactivated and set to OFF.
The current trigger status is shown above the keys
for the ventilation parameters (H).
