External exhalation system
Should the unit fail, the exhalation system enables you to
breath through the nose or mouth. Full-face masks must
also be fitted with a safety valve. Remove the mask as
quickly as possible. First check whether there has been a
power failure. Follow the instructions for use of your ex-
haled air system.
Bacteria filter
If SOMNO
comfort
2e is to be used by several patients (e.g.
in a hospital), a bacteria filter should be used to protect
against infection. It is installed between the breathing
hose and the adapter. Using a bacteria filter can reduce
the pressure and flow rate.
Follow the manufacturer's instructions carefully, especially
with regard to the use-by date of the bacteria filter.
Oxygen supply
For safety reasons (risk of fire) the direct introduction of
oxygen into the breathing hose or the mask without any
special protective device is not permitted. However, the
supply of up to 4 l/min oxygen to the breathing mask is
possible when using the oxygen connection valve
WM 24042.
An oxygen concentrator (e.g. Oxymat), liquid oxygen or an oxygen cylinder with a suitable
pressure reducer may be used. This application must be prescribed by the doctor in charge.
To prevent oxygen entering the therapy unit, the SOMNO
comfort
2e automatically gener-
ates a therapy pressure of at least 5 hPa when an oxygen connection valve is attached. You
must under all circumstances follow the safety instructions for handling oxygen as well as
the operating instructions for the oxygen valve and the oxygen unit used.
