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
fitted to frame.
Turn off the CPAP or bilevel device and remove
mask. Refit 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 your face
during fitting 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 refitting.
If the problem persists, talk to your clinician.
Talk to your clinician to have your face size checked
against fitting template. Note that sizing across
different masks is not always the same.
The Quattro FX/Quattro FX for Her cushion is
