Fitting the mask
The diagrams in section A on the illustrations sheet show how the parts of the
mask fit together.
The diagrams in section B show the suggested sequence for obtaining the
best fit and comfort in using your mask. Please follow these instructions
carefully.
1 Wash your face thoroughly before fitting the mask. It is recommended that
you do not apply moisturizer where the mask contacts your face as it can
affect the mask seal.
2 Place the headgear on your head, like you would a cap, and pull the mask
forward onto your face (B-1). Make sure that the headgear fits evenly on the
top of your head.
3 Fit the mask over your mouth. Insert the pillows so that they sit gently just
inside the entrance to your nostrils.
4 Push the lower headgear clips into the slots on the mask frame until they
click into place (B-2).
5 To tighten or loosen the headgear straps, peel the Velcro
headgear and reposition it. Gently and evenly adjust the upper headgear
straps (B-3), then the lower straps (B-4). Alternate the adjustment of each
set of straps until they are comfortable and firm and so that the upper
headgear clips rest between your eye and your ear. The mask should gently
'float' on your face. Do not overtighten the headgear straps.
6 Connect one end of the main air tubing to your flow generator and the other
end to the swivel.
7 Connect the elbow to the mask frame, holding the sides of the elbow then
firmly pushing it onto the frame until it clicks into place (B-5). Rotate the
elbow to check that it rotates freely and does not separate from the frame.
8 Turn your flow generator on.
9 If you feel air leaks, you may need to adjust your headgear. Return to step 5
or check through the suggestions in "Optimizing mask seal and comfort"
below.
Optimizing mask seal and comfort
To receive effective therapy it is important to have the best seal possible
between your mask and your face. If you are experiencing leaks, please ensure
that you have followed the fitting instructions carefully. Carry out a quick check
after fitting your mask:
•
Is the mouth cushion creased? Creases can allow air to leak out of the
mask.
