SPECIAL NOTES
SAFETY SUMMARY
To ensure the safe and proper installation and use of the
Invacare Twilight Nasal Mask and Headgear, these
instructions MUST be followed:
WARNING
This Twilight Nasal Mask should be used only with
CPAP systems recommended by your physician or
respiratory therapist. A mask should not be used unless
the CPAP system is turned on and operating properly.
NEVER block the vent hole or holes associated with
the mask.
Explanation of Warning: CPAP systems are intended
to be used with special masks with connectors which
have vent holes to allow continuous flow of air out of
the mask. When the CPAP machine is turned on and
functioning properly, new air from the CPAP machine
flushes the exhaled air out through the attached mask
exhalation port. However, when the CPAP machine is
not operating, not enough fresh air is provided through
the mask, and exhaled air may be rebreathed.
Rebreathing of exhaled air for longer than several
minutes can in some circumstances lead to suffocation.
This warning applies to most models of CPAP systems.
The entire mask system is for single patient use, and
must not be reused on another person. This is to avoid
risk of cross-infection.

HEADGEAR/MASK ASSEMBLY, PLACEMENT
HEADGEAR/MASK ASSEMBLY, PLACEMENT
AND USAGE (FIGURE 1)
NOTE: Wash the headgear before using it for the first time, as dye may
run. Refer to CLEANING THE MASK AND HEADGEAR in this manual.
NOTE: Invacare recommends washing your face before fitting the
mask. This will remove excess facial oil and extend the life of the mask.
1. Check the nasal mask, ensuring that the nasal cushion is attached,
the swivels function, and the exhalation ports are clear.
2. Attach the headgear to the nasal mask by sliding the upper
headgear straps through the loophole of the forehead support.
3. Adjust each strap by folding it back and attaching it to itself,
using the hook and loop fastener straps.
4. Slide the lower headgear strap through the loopholes of the
headgear clips.
5. Loosely secure the straps by folding them back and using the
hook and loop fastener straps.
6. Connect a standard 22mm bore, 6-foot tube from your flow
generator to the tubing swivel by pressing the tube end over
the swivel.
7. Turn ON the flow generator BEFORE placing the mask on
your face.
8. Place mask on face with headgear straps behind head.
9. Adjust the mask position on the nose. Depress the forehead
support adjustment tab and slide the forehead support up or
down until it contacts the forehead and the upper portion of the
nasal cushion lightly touches the bridge of the nose. The mask
should fit comfortably.
10. Place the mask loosely over the nose, with minimal pressure.
11. Attach the headgear clips to the nasal mask.
NOTE: If a leak occurs, tighten the headgear straps by readjusting the
hook and loop fasteners.
WARNING
DO NOT pull the straps too tight, this can cause skin
irritation and may deform the nasal cushion, causing a leak.
If the mask and headgear are adjusted correctly and a
problem persists, contact your healthcare professional.
