Adjusting The Therapy; Adjusting The Apl Valve - Dräger Perseus A500 Instructions For Use Manual

Adjusting the therapy

Adjusting the APL valve

The pressure limitation set with the APL valve only
takes effect during manual ventilation or
spontaneous breathing.
WARNING
Risk of excessively high airway pressures
If the ventilator fails, the device switches into
the MAN / SPON ventilation mode.
The APL valve should also be set to a
pressure limitation value suitable for the
patient when using automatic ventilation
modes. If the ventilator fails, ventilate the
patient manually.
 The selection between manual ventilation
(Man) and spontaneous breathing (Spont) is
made at the APL pressure limitation valve, see
page 16.

The patient can be manually ventilated with the
breathing bag. The pressure is limited by the set
value.
In the Manual / Spontaneous mode, lifting the
valve head relieves pressure from the breathing
system.
Spontaneous breathing
 Turn the APL valve counterclockwise as far as
it will go.
The points are vertically aligned and the valve
head is raised.
The pressure limitation is canceled and the valve is
open for free spontaneous breathing.
