WARNING
•
The technical specifications of the mask are provided for your
clinician to check that they are compatible with the CPAP or bilevel
device. If used outside specification or if used with incompatible
devices; the seal and comfort of the mask may not be effective;
optimum therapy may not be achieved; and leak, or variation in
the rate of leak may affect the CPAP or bilevel device function.
• Discontinue using this mask if you have ANY adverse reaction to
the use of the mask, and consult your physician or sleep therapist.
• Using a mask may cause tooth, gum or jaw soreness or aggravate an
existing dental condition. If symptoms occur, consult your physician
or dentist.
• As with all masks, some rebreathing may occur at low CPAP
pressures.
• Refer to your CPAP or bilevel device manual for details on settings
and operational information.
Tighten both upper and lower headgear
straps. Do not overtighten.
Turn off the CPAP or bilevel device and
remove mask. Refit the mask according to
the instructions.
Ensure you position the cushion correctly
on the face before pulling headgear over
the head.
Do not slide mask down the face during
fitting as this may lead to folding or curling
of the cushion.
Disassemble the mask, then reassemble
according to the instructions.
Clean cushion according to the
instructions.
Talk to your clinician to have your face size
checked against the fitting template. Note
that sizing across different masks is not
always the same.
