Remark
The adjustment ranges of the ventilation parameters can limit
each other and may vary, depending on the situation.
The selector indicates the parameter which is limiting an adjust-
ment range.
To cancel the entry, press the button of the selected parameter once again.
7.3.4
Trigger
The trigger function synchronises the ventilator and the patient. Depending on
the selected ventilation mode and patient activities, mandatory ventilation strokes
can be initiated via a flow or a pressure trigger, or the pressure support PS can
be activated to enable deeper spontaneous breaths. The ventilator detects the
patient's attempts to breathe in via the trigger, and the trigger sensitivity can be
individually adapted to the patient. The lower the set value the more sensitive the
ventilator is to patient's attempts at inhaling. At very low sensitivities, the elasticity
of the ventilation tubes could cause a trigger signal (auto-triggering).
Inspirations initiated by the trigger variable are coloured on the pressure curve.
Different colours are assigned to mandatory and spontaneous triggers for differ-
entiation.
If the triggered breaths are not coloured, the function may not have been activat-
ed. Change the configuration accordingly (to open the menu, tap and keep your
finger on the curve) or contact your service technician.
Switching between flow and pressure trigger is done with the selector at the
minimum trigger value or at OFF. The indication “Flow” and “Press.” is displayed
as appropriate. The desired trigger function is available after selection and con-
firmation.
Remark
When the trigger function is switched off, no pressure support is
available in any of the modes to assist spontaneous breathing.
7.3.5
Backup ventilation
A backup ventilation mode, which completely takes over the patient's ventilation
in case of apnoea, is associated with each ventilation mode.
Tap the “Backup” button to configure the backup ventilation parameters.
