Thank you for choosing the AirFit™ N20/AirTouch™ N20. These masks
are identical - except for the interchangeable AirFit N20 silicone cushion
and AirTouch N20 foam cushion. This offers two choices for your mask,
depending on your preferred comfort, stability and seal. These masks
may not be available in all countries.
Intended use
The AirFit N20 and AirTouch N20 nasal masks channel airflow non-
invasively to a patient from a positive airway pressure (PAP) device such
as a continuous positive airway pressure (CPAP) or bilevel device.

2
The N20 is:
•to be used by patients weighing more than 30 kg for whom positive
airway pressure has been prescribed
•intended for single-patient re-use in the home environment and multi-
patient re-use in the hospital/institutional environment.
AirTouch N20 cushion
The AirTouch N20 cushion is intended for single patient re-use in both the
home and hospital/institutional environment and recommended to be
replaced monthly.
WARNING
Magnets are used in the lower headgear straps and the frame of the
AirFit N20. Ensure the headgear and frame is kept at least 2" (50 mm)
away from any active medical implant (eg, Pacemaker or
defibrillator) to avoid possible effects from localized magnetic fields.
The magnetic field strength is less than 400 mT.
Clinical benefits
The clinical benefit of vented masks is the provision of effective therapy
delivery from a therapy device to the patient.
Intended patient population/medical conditions
Obstructive pulmonary diseases (eg, Chronic Obstructive Pulmonary
Disease), restrictive pulmonary diseases (eg, diseases of the lung
parenchyma, diseases of the chest wall, neuromuscular diseases), central
respiratory regulation diseases, obstructive sleep apnoea (OSA) and
obesity hypoventilation syndrome (OHS).
Contraindications
Use of masks with magnetic components is contraindicated in patients
with the following pre-existing conditions:
•a metallic hemostatic clip implanted in your head to repair an
aneurysm
•metallic splinters in one or both eyes.

English 3
Fitting your mask
1. Twist and pull both magnetic clips away from the frame.
2. With both lower headgear straps released, hold the mask against your
face and pull the headgear over your head.
Headgear check:
Ensure that the ResMed logo on the headgear is facing outwards and
is upright when the headgear is put on.
3. Bring the lower straps below your ears, and attach the magnetic clip
to the frame.
4. Undo the fastening tabs on the upper headgear straps. Adjust the
straps evenly until the mask sits comfortably just over the nose.
Reattach the fastening tabs.
5. Undo the fastening tabs on the lower headgear straps. Adjust the
straps evenly until the mask is stable. Reattach the fastening tabs.
6. Connect the device air tubing to the short tube. Attach the elbow to
the mask by pressing the side buttons and pushing the elbow into the
mask, ensuring it clicks in on both sides.
7. Your mask and headgear should be positioned as shown in the
illustration.

Adjusting your mask
If necessary, slightly adjust the position of the mask for the most
comfortable fit. Ensure that the headgear is not twisted and for the AirFit
N20 the cushion is not creased.
1. Turn on your device so that it is blowing air.
Adjustment tips:
To resolve any leaks at the upper part of the mask, adjust the
upper headgear straps. For the lower part, adjust the lower
headgear straps. Adjust only enough for a comfortable seal.
The upper strap adjustment is the key to seal and comfort.
Do not overtighten the lower straps because they mainly serve to
keep the cushion in position.
Removing your mask
1. Twist and pull both magnetic clips away from the frame.
2. Pull the mask away from your face and back over your head.

English 5

its life
Cushion performance may deteriorate as the foam nears
the end of its lifespan. Adjust your headgear and if the
problem persists, replace the cushion.
Mask is not tightened
correctly.
Ensure that the headgear straps are not overtightened or
too loose. You may find that this mask does not need to
be tightened as much as other nasal masks.
Check that the headgear is not twisted.
Mask may be the wrong size. 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.
Mask does not fit properly.
Mask is incorrectly
assembled.
Disassemble the mask, then reassemble according to the
instructions.
Mask may be the wrong size. Talk to your clinician to have your face size checked
against the fitting template, Note that sizing across

GENERAL WARNINGS
•The vent holes must be kept clear.
•The mask should only be used with CPAP or bilevel devices recommended by a
physician or respiratory therapist.
•The mask should not be used unless the device is turned on. Once the mask is fitted,
ensure the device is blowing air. Explanation: CPAP and bilevel devices are intended to
be used with special masks (or connectors) which have vent holes to allow continuous
flow of air out of the mask. When the device is turned on and functioning properly,
new air from the device flushes the exhaled air out through the mask vent holes.
However, when the device is not operating, insufficient fresh air will be provided
through the mask, and the exhaled air may be rebreathed. Rebreathing of exhaled air
for longer than several minutes can, in some circumstances, lead to suffocation. This

English 9
GENERAL WARNINGS
applies to most models of CPAP or bilevel devices.
•Follow all precautions when using supplemental oxygen.
•Oxygen flow must be turned off when the CPAP or bilevel device is not operating, so
that unused oxygen does not accumulate within the device enclosure and create a risk
of fire.
•Oxygen supports combustion. Oxygen must not be used while smoking or in the
presence of an open flame. Only use oxygen in well ventilated rooms. At a fixed rate
of supplemental oxygen flow, the inhaled oxygen concentration varies, depending on
the pressure settings, patient breathing pattern, mask, point of application and leak
rate. This warning applies to most types of CPAP or bilevel devices.
•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.
•Remove all packaging before using the mask.
•The mask must be used under qualified supervision for users who are unable to
remove the mask by themselves.
•This mask is not for use on patients with impaired laryngeal reflexes or other
conditions predisposing to aspiration in the event of regurgitation or vomiting.
•Avoid connecting flexible PVC products (eg, PVC tubing) directly to any part of the
mask. Flexible PVC contains elements that can be damaging to the materials of the
mask, and may cause the components to crack or break.
•The N20 line of nasal CPAP masks are not intended to be used simultaneously with
nebulizer medications that are in the air path of the mask/tube.
•The mask contains an exhaust port safety feature to enable normal breathing. The
mask should not be worn if this safety feature is damaged or missing.
Note: For any serious incidents that occur in relation to this device, these should be
reported to ResMed and the competent authority in your country.
