3.7 Compatible devices and
accessories
Therapy units
YARA and YARA NV masks can be combined
with all units designed for carrying out the
therapies described under "Intended Use".
Note that if unsuitable device combinations are
used, the actual pressure in the mask may not
correspond to the therapy pressure you have
been prescribed.
This may also happen even if the correct
pressure is indicated on the therapy unit. Have
your device combination adjusted by a doctor
or distributor so that the pressure in the mask
corresponds to your therapy pressure.
Humidifier
YARA and YARA NV can be used with both
cold and warm-air humidifiers.
Never set the humidification level so high that
condensation forms in the air hose. Follow the
instructions for use of your humidifier and
therapy unit.
Quick release system (optional) (Fig. I)
To open the headgear in an emergency (e.g.
vomiting) a quick release system can be
supplied as an accessory.
The quick release system consists of a special
clip with ripcord, which is fitted instead of one
of the lower headgear clips.
In an emergency, simply pull the ripcord. The
special clip will detach itself from the mask. The
headgear is now open and the mask can be
removed.
