Solution
Remove the elbow from your mask, then
reassemble according to the instructions.
Clean with a soft bristle brush until the vent
is clear.
Refit your mask according to the instructions.
Ensure that you position the cushion correctly
on your face before pulling headgear over
your head. Do not slide the mask down your
face during fitting as this may lead to folding
or curling of the cushion.
Talk to your clinician to have your face size
checked against fitting template. Note that
sizing across different masks is not always
the same.
Remove the rest of the mask from the frame,
then reassemble according to the
instructions.
The mask contains passive venting to protect against
rebreathing. As a result of manufacturing variations, the vent
flow rate may vary.
