Solution
Refit or reposition your mask.
Readjust the headgear straps to bring the
mask closer to the face and improve your
seal.
Check that your mask is assembled correctly.
Check that the mask size indicator is facing
downward on the bottom of the cushion along
the bottom of your nose.
Pull the mask away from your face and
reposition, ensuring that the lower corners of
the mask fully enclose your nose. If
necessary, readjust the headgear straps to
keep the mask in the right place.
Clean the cushion according to the
instructions.
Remove and refit your mask according to the
fitting instructions. Ensure that you position
the cushion correctly over your nose before
pulling the 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.
Ensure that the headgear straps are not
overtightened or too loose. You may find that
this mask does not need to be tightened as
much as other nasal masks.
Check that the headgear is not twisted.
Talk to your clinician.
Disassemble the mask, then reassemble
according to the instructions.
Talk to your clinician.
