not operating.
Explanation of the Warning: When the
CPAP or bilevel device is not in
operation, and the oxygen flow is left
on, oxygen delivered into the ventilator
tubing may accumulate within the flow
generator enclosure. Oxygen
accumulated in the CPAP or bilevel
device enclosure will create a risk of fire.
This warning applies to most types of
CPAP or bilevel flow generators.
Please refrain from smoking while
•
oxygen is in use.
Using a mask may cause tooth, gum or
•
jaw soreness or aggravate an existing
dental condition. If symptoms occur,
consult your physician or dentist.
Note:
At a fixed rate of supplemental
oxygen flow, the inhaled oxygen
concentration will vary, depending on the
pressure settings, patient breathing pattern,
mask selection and leak rate.

1 Place the headgear on the head. Adjust
the side vertical straps so that the lower
strap sits just below the ear (not
touching it) and at the base of the head
(Fig. C-1).
2 The headgear clip should be parallel
with the nose and not in the line of
vision. Check that the crossover is as far
forward as possible (Fig. C-2).
To adjust the crossover to a forward
position, slide the crossover buckle
along one strap (Fig. C-2a) and then
along the other strap (Fig. C-2b).

Alternate the movement on each side
until the crossover is as far forward as
possible.
3 Ensure that the crossover and the rear
straps lie flat against the head.
4 Place the mask on the nose (Fig. C-3).
Clip the mask to the headgear.
5 Adjust the lower straps by pulling firmly
(Fig. C-4) so that the rear straps fit
securely around the base of the head
(Fig. C-4a).
6 Connect one end of the main air tubing
to your flow generator and the other
end to the swivel.
Note:
The swivel, short air tubing and
mask elbow are supplied assembled.
7 Turn your flow generator on.
8 Connect the mask elbow to the mask
frame. To do this, hold the sides of the
mask elbow (Fig. C-5) and firmly push
the elbow onto the mask frame until it
clicks into place.
Check that you have connected the
mask elbow correctly by rotating it. Be
careful not to squeeze the sides of the
elbow. If the mask elbow is fitted
correctly, it should rotate freely and not
separate from the mask frame.
9 Adjust the angle of the mask by selecting
the setting that provides a comfortable
fit with minimum or no leak.
To test each setting, hold down the
Angle Selector Tab (Fig. C-6) and move
the headgear clip up or down
(Fig. C-6a) as required. You may need
to raise the headgear clip when moving
it from one setting to the next.
The mask can be tilted at five different
positions. If you feel excessive pressure
on the middle of the nose, tilt the mask
down. Alternatively, if you feel excessive
pressure on your upper lip, tilt the mask
up.
