APL Valve

Warning:
Route all lines/cables away from the
APL valve to prevent interference with
the APL valve adjustment knob.
Lines/cables caught underneath the
APL valve adjustment knob could
interfere with proper functioning of this
valve.
The following numbers in boldface refer to
The APL valve (1) has two functions. It limits the
maximum pressure during manual ventilation. It also
exhausts excess gas into the scavenger system
during manual and spontaneous ventilation.
The APL valve is connected to the patient airway
through the ventilator. It functions only when the
ventilator is in ManSpont mode or ventilator override
condition.
The APL valve has a labeled knob (2) for selecting
between spontaneous and manual modes of
ventilation and for indicating approximate pressure
settings.
When the APL valve knob is rotated fully
counterclockwise, pressure is released for
spontaneous ventilation. Spontaneous ventilation
automatically eliminates resistance to patient
exhalation.
In manual mode, the APL valve knob can be rotated
to change the pressure threshold at which gas will
flow through the valve and into the scavenging
system. Clockwise rotation of the APL valve knob
increases the pressure threshold, and
counterclockwise rotation of the APL valve knob
decreases the pressure threshold. Lifting the top of
the APL valve knob will temporarily relieve pressure.
Note:
The APL valve is automatically excluded
from the breathing circuit whenever an
automatic ventilator mode is selected.
