Problem/possible cause Solution
Mask leaks around the face
Cushion membrane is
creased or folded.
Cushion incorrectly
inserted into frame.
Mask could be the wrong
size.
Spring frame incorrectly
fi tted to frame.
Turn off the CPAP or bilevel device and remove
mask. Refi t your mask according to the
instructions. Ensure you position the cushion
correctly on your face before pulling headgear
over your head. Do not slide mask down the
face during fi tting as this may lead to folding or
curling of the cushion.
Remove cushion from frame and reinsert
starting at the top. Line up raised section on
cushion with recess in top of frame. Ensure
the alignment markers at bottom corners of
the cushion line up with the indent features on
frame. Ensure cushion membrane looks even
before refi tting.
If the problem persists, talk to your clinician.
Talk to your clinician to have your face size
checked against fi tting template. Note that
sizing across different masks is not always the
same. The cushion is designed to sit mid-bridge.
Remove the spring frame from the frame, then
reassemble according to the instructions.
