7.14 MPVp mode
MPV mode (mouthpiece ventilation mode) is a spontaneous
breathing mode in which the patient decides freely when to
get breathing support. A pressure level on inspiration and an
inspiration time are set. The graph shows the currently
regulated airway pressure over time.
7.14.1 Adjustable parameters in MPVp mode
7.15 MPVv mode
MPV mode (mouthpiece ventilation mode) is a spontaneous
breathing mode in which the patient decides freely when to
get breathing support. A volume on inspiration and a
pressure level on inspiration are set.
The graph shows the currently regulated airway pressure
over time.

Set trigger sensitivity here:
1: Highly sensitive
10: Not very sensitive
Auto: Device optimizes trigger sensitivity.
Trigger
sensitivity on
exhalation
95 % – 5 %
Set trigger sensitivity on exhalation here. Triggering is effected when
the following values are reached by maximum flow:
95 %: Highly sensitive
5 %: Insensitive
Trigger
