Removing The Mask; Disassembling The Mask - ResMed Mirage Quattro Guia Del Usuario

6 Test the functioning of the valve by sealing the swivel with your hand and
ensuring that you can still breathe freely.
7 Connect the main air tubing to the swivel (Fig. B-6). Then connect the free
end of the air tubing to your flow generator and turn the flow generator on.
8 Lie down in your sleeping position. Twist the forehead support dial
(Fig. B-7) until you feel that the mask is evenly positioned on your face. It
should be comfortable, with a satisfactory seal. Gently tighten the lower
headgear straps if necessary.
9 The fitted mask is shown in Fig. B-8.
Optimising 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 mask cushion creased? Creases can allow air to leak out of the mask.
•
Have you cleaned your mask cushion recently? Oils on the cushion can
affect the seal.
• Are your headgear straps overtightened? Try not to alter the upper headgear
straps once they have been tightened by your clinician.
•
You may need to slightly adjust the dial. Note the dial setting when
comfortable.
•
Does the mask seem too close to your eyes? You may need a smaller mask.
If you cannot resolve any problems, look at the Troubleshooting section, or talk
to your clinician. You may require another mask size.

Removing the Mask

To remove the Mirage Quattro, disconnect one of the lower headgear clips and
pull the mask and headgear up over your head.

Disassembling the Mask

See section C on the illustrations sheet.
1 Detach the air tubing.
2 Unclip the lower headgear clips (Fig. C-1) and unhook the upper headgear
straps (Fig. C-2). It is not necessary to remove the headgear clips from the
headgear.
3 Remove the elbow assembly from the mask frame (Fig. C-3). It's easier to
pivot the bottom of the elbow away from the mask frame than to pull the
elbow straight off.
4 Remove the valve clip from the elbow (Fig. C-4).
