This can be combined with the ventilation modes SIPPV, SIMV
and PSV.
The inspiratory plateau pressure is automatically regulated
between P
and PEEP such that the set tidal volume VTset
insp
is applied.
VG requires a ventilation mode with a plateau.
This function is used for patients who are to be ventilated with
a constant tidal volume.
If the yellow LED blinks, consider:
–
The inspiration time is set too short. PSV/VG stroke has
ended.
–
The Tidal volume delivered is less than the VG tidal volume
set. The »VT low« alarm may activate.
Press the key »Vent. Option«.
Press the key »VG« and set the desired tidal volume VTset
with the keys »

Press the key »On«.
The tidal volume and the peak pressure of the regulated
ventilation stroke are displayed.
Adjust the rotary knobs »T

When switching from a ventilation mode (SIPPV, SIMV or
