Trigger threshold
The adjustable trigger threshold determines the
volume the patient must inhale in order to trigger a
mechanical breath. The settings from 1 to 10
correspond to a trigger threshold of approx. 0.02 to
3 mL.
Begin with a low trigger threshold. This
corresponds to a high trigger sensitivity. If auto-
triggering occurs, increase the trigger threshold.
An increased trigger threshold delays the
mechanical breath.
The display
Trigger
lights up briefly with each
mechanical breath triggered.
Setting the trigger threshold
1
Press the
Vent. Option
key.
The trigger threshold currently set (
Trigger
) is
displayed.
2
Reduce the trigger threshold by pressing the
key.
3
Increase the trigger threshold by pressing the
key.
Ventilation with pressure plateau
The patient can be ventilated with or without a
pressure plateau in the
IPPV/IMV
,
SIPPV
, and
SIMV
ventilation modes.
In the
PSV
ventilation mode and when using the
additional setting
VG
, the pressure plateau must
always be set.
If a pressure plateau is set, inspiratory pressure is
limited to
Pinsp
.
Limiting the pressure to
Pinsp
prevents damaging
pressures, e.g., if compliance decreases. The
pressure plateau benefits the diffusion of the
breathing gas in the lungs.
1
Adjust the view so that the pressure waveform
and the measured pressure values are
displayed, see page 87.
2
Adjust ventilation using the following setting
knobs:
Pinsp
,
PEEP/CPAP
,

3
Adjust the view so that the flow waveform and
the measured volume values are displayed,
see page 87.
4
Adjust the tidal volume using the following
setting knobs:
Pinsp
,
PEEP/CPAP
5
Set the alarm limits, see page 84.
CAUTION
Risk of patient injury
High trigger sensitivity may lead to auto-
triggering of the ventilator.
Set the trigger threshold accordingly.
