Mask is not positioned correctly. Check that the ResMed logo is
facing upward on the top of the
cushion across the bridge of your
nose.
Mask may have been fitted
incorrectly.
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 top strap to keep the
mask in the right place.
Cushion membrane is creased or
folded.
Remove and refit your mask
according to the fitting instructions.
Ensure 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.
Mask is not tightened correctly. Ensure that the headgear straps are
not overtightened or loose.
Readjust the back strap to bring the
mask closer to the face and improve
your seal.
Check that the headgear is not
twisted.
Mask may be the wrong size. Talk to your clinician.
