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.

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.

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.
