Exhalation System; Anti-Asphyxia Valve - Weinmann JOYCEeasy Manual De Instrucciones

With many combinations of device, the
actual pressure in the mask will not
correspond to the prescribed therapy
pressure, even if the therapy device is
displaying the correct pressure. Have the
combination of devices adjusted by a
physician or specialist dealer so that the
actual pressure in the mask corresponds to
therapy pressure.
Quick-release cord (optional)
You can use a quick-release cord (accessory)
to open the headgear in emergency
situations (e.g. vomiting).
The quick-release cord consists of a special
clip with a cord which you can fit to the
mask instead of one of the bottom
headgear clips.
In an emergency, simply pull the quick-
release cord. The special clip will detach
itself from the mask. The headgear is now
open and the mask can be removed
(figure G).

3.3 Exhalation system

The mask has an integrated exhalation
system. The retaining ring and mask body
are shaped in such a way that a gap forms
between these parts. The exhaled air can
escape through this gap (figure A2).

3.4 Anti-asphyxia valve

Risk of asphyxia if anti-asphyxia valve
not working properly!
Residues may block the mask and
jeopardize the success of therapy.
 Check before each use that the anti-
asphyxia valve is working properly.
 Clean contact surfaces between the
elbow and the rotating sleeve
thoroughly.
Safety function of the anti-asphyxia
valve
The anti-asphyxia valve has an opening to
the atmosphere through which the patient
can inhale ambient air if the therapy device
fails. This significantly reduces the risk of
breathing CO back in and thus also the risk
2
of asphyxia. Inside the anti-asphyxia valve is
a membrane which can adopt one of two
positions:
• as long as the therapy device is in
operation, the air flow forces the
membrane against the opening to the
atmosphere and seals it completely. The
patient breathes through the therapy
device.
• if the therapy device fails or if the device
is not connected, the membrane is in the
rest position, in other words the
opening to the atmosphere is free. The
patient breathes ambient air through
this opening.
