between these parts. The exhaled air can escape
through this gap.

 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.

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.
