size.

of ears.
Cushion is riding up the
face during use.
Spring frame is sitting too
close to the eyes.

Solution
The cushion membrane is designed to inflate
against your face to provide a comfortable
seal with low headgear tension. Adjust straps
evenly. Ensure that the headgear straps are not
too tight and that the cushion is not crushed or
creased.
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 cushion is designed to sit
mid-bridge.
Remove and refit your mask according to the
instructions. Check that the top and bottom
headgear straps are correctly positioned.
Ensure that the Velcro tab is correctly aligned
with headgear material and not cutting into top
of ear.
Check headgear positions against the
instructions. Headgear should not be worn too
far back on the head. Headgear may be the
wrong size. If the problem persists, talk to your
clinician.
