Warning!
Oronasal masks must be fitted with an emergency exhalation valve so that you can
breathe through your nose or mouth even if the device fails. Oronasal masks with-
out an emergency exhalation valve may not be used!
External exhalation system
On some masks, there is no integrated exhalation system. To enable used air containing
carbon dioxide (CO
2
) to escape, an external exhalation system is required on these masks.
Follow the instructions for use for the mask.
Warning!
Without an exhalation system, the CO
2
concentration in the mask and tube may
rise to critical values and thus obstruct your breathing. Risk of asphyxiation!
– Fit the external exhalation system between the
breathing mask and the breathing tube.

Bacteria filter
If the therapy device is intended for use by several patients (e.g. in hospital), a bacteria filter
should be used to protect against infections.
– Fit the bacteria filter between the breathing tube with
click adapter and the device.
Caution!
When using a bacteria filter, pressure consistency
and flow rate may be reduced. If a bacteria filter is
connected, check the pressure. Note the manufac-
turer’s information, especially the expiry date for
the filter.
