External exhalation system
No exhalation system is integrated in some masks. In order for the used, carbon
dioxide (CO
2
)-enriched air to be able to escape, an external exhalation system is re-
quired on these masks. Follow the instructions for use of your exhaled air system.
Warning!
Without an exhalation system the CO
2
concentration would rise to critical
values in the mask and hose, thus hindering your breathing. Risk of
suffocation!
– Fit the external exhalation system between the
breathing mask and the breathing tube.

Bacteria filter
If the CPAP 20e is to be used by several patients (e.g.
in a hospital), a bacteria filter should be used to pro-
tect against infection. It is inserted between the
breathing tube and the device outlet port. Using a
bacteria filter can reduce the pressure and flow rate.
