Nasal Mask
Thank you for choosing the AirFit N20 Classic. This document provides
the user instructions for the AirFit N20 Classic.
Using this guide
Please read the entire guide before use. When following instructions,
refer to the images at the front of the guide.
Intended use
The AirFit N20 Classic channels 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 AirFit N20 Classic 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.
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

2
circumstances, lead to suffocation. This 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. The mask may not
be suitable for those predisposed to aspiration.
•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 nebuliser medications that are in the air path
of the mask/tube.

English 3
•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.
Using your mask
When using your mask with ResMed CPAP or bilevel devices that have
mask setting options, refer to the Technical specifications section in this
user guide for the correct setting.
For a full list of compatible devices for this mask, see the Mask/Device
Compatibility List on www.resmed.com/downloads/masks. If you do not
have internet access, please contact your ResMed representative.
Fitting
1. With both lower headgear straps released, hold the mask against your
face and pull the headgear over your head.
2. Bringing the lower straps below your ears, loop the headgear into the
lower hooks on the mask frame.
3. Undo the Velcro®tabs on the upper headgear straps. Adjust the straps
evenly until the mask sits comfortably just over the nose. Reattach the
Velcro tabs.
4. Undo the Velcro tabs on the lower headgear straps. Adjust the straps
evenly until the mask is stable. Reattach the Velcro tabs.
5. Connect the device air tubing to the elbow. 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.
6. Your mask and headgear should be positioned as shown in the
illustration.
Adjustment
If necessary, slightly adjust the position of the mask for the most
comfortable fit. Ensure that the cushion is not creased and the headgear
is not twisted.
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.

Ensure the headgear straps are not overtightened or too loose.
Removal
1. Unloop the lower headgear straps from the lower hooks of the frame.
2. With both lower straps released, pull the headgear back over your
head.
Disassembly
If the mask is connected to your device, disconnect the device air tubing
from the elbow.
1. Pull the straps out of the frame.
2. Remove the elbow from the mask by pressing the side button and
pulling the elbow away.
3. Pull the cushion away from the frame.
Reassembly
1. Push the cushion into the frame.
Note: Ensure the cushion mask size indicator is facing downwards.
2. Attach the top headgear straps to the mask frame by looping onto
each of the upper headgear hooks.

mask.
Cleaning your mask at home
It is important to follow the steps below to get the best performance out
of your mask.
WARNING
•As part of good hygiene, always follow cleaning instructions and
