4.3 Exhalation system
vented variants
Vented variants (transparent elbow and rotating
sleeve) have an integrated exhalation system. The re-
taining ring and mask body are shaped so that there
is a gap between these parts. The exhaled air can es-
cape through this gap.
Non-vented variants
Non-vented variants (blue retaining ring and elbow)
do not have an exhalation system. Only use non-vent-
ed full-face masks in combination with therapy devic-
es which have an active exhalation valve and have
alarms and safety systems for any device failure. If you
are using the non-vented variant with an external ex-
halation valve, please see the associated instructions
for use.
4.4 Anti-asphyxia valve
Risk of asphyxia if anti-asphyxia valve not
working properly!
Residues may cause the valve to stick and lead to
CO
being re-inhaled.
2
Check before every use that the openings of the
anti-asphyxia valve are clear.
If the therapy device fails, the anti-asphyxia valve
opens so that the patient can breathe ambient air.
4.5 Pressure measurement port
The mask has a pressure measurement port, which
can be used for measuring pressure or supplying oxy-
gen. If you are not using the connection, close it with
the seal for pressure measurement to reach therapy
pressure.
5
Hygiene treatment
Risk of injury from inadequate cleaning!
Residues may congest the mask, impair the
integrated exhalation system and jeopardize therapy
success.
For patients with a compromised immune system
or particular background of illness, disinfect
mask components daily following consultation
with the physician.
5.1 Clean mask
1. Dismantle mask (see Figure
).
2. Clean mask in accordance with the table below:
Action
Wash mask components with warm water and
X
a mild detergent.
When washing mask parts (except for mask
cushion and forehead cushion), clean thor-
oughly with a cloth or a soft brush.
Wash headgear by hand.
3. Rinse all parts with clear water.
4. Allow all parts to air-dry.
5. Perform a visual inspection.
6. If necessary: replace damaged parts.
7. Re-assemble mask (see Figure
).
r
Discolorations of mask components do
not impair the functionality of the mask.
5.2 Change of patient
In the clinical sphere only: You must subject the mask
to a hygiene treatment in the event of a change of
patient. Information on the hygiene treatment with a
change of patient can be found in a brochure avail-
able on the manufacturer's website. We will also send
you this brochure on request.
