Solution
Mask leaks around face.
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.
Mask does not fit properly.

assembled.
Disassemble the mask, then reassemble

that the printing on the left headgear strap
(Swift FX) aligns to the printing on the
cushion arm (Nano).
Mask may be the wrong
size.
Talk to your clinician.
