Non-vented Full Face Mask
Thank you for choosing the Quattro Air Non-Vented (NV) full face mask.
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 Quattro Air NV is a non-invasive accessory used for channelling
air-flow (with or without supplemental oxygen), intended to be used
with active-exhaust-valve ventilators, to provide ventilatory assistance
to patients with respiratory insufficiency and respiratory failure.
The Quattro Air NV is:
•to be used by patients weighing >30 kg requiring non-life support
ventilatory assistance.
•intended for single patient re-use in the home environment and/or
multi-patient re-use in the hospital/institutional environment.
Clinical benefits
The clinical benefit of non-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, and obesity hypoventilation
syndrome (OHS).
GENERAL WARNINGS
•The mask must not be used without qualified supervision for
patients who are unable to remove the mask themselves.

2
•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.
•The mask should only be used with ventilators recommended by
a physician or respiratory therapist.
•The mask should not be worn unless the ventilator system is
turned on and operating properly.
•Follow all precautions when using supplemental oxygen.
•If oxygen is used with the ventilator, the oxygen flow must be
turned off when the ventilator is not operating, so that unused
oxygen does not accumulate within the device enclosure and
create a risk of fire.
•At a fixed rate of supplemental oxygen flow (if used), the inhaled
oxygen concentration varies depending on the pressure settings,
patient breathing pattern, mask size selection and leak rate.
•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.
•The technical specifications of the mask are provided for your
clinician to check that they are compatible with the ventilator. 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 ventilator 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.
•Refer to your ventilator manual for details on settings and
operational information.
•Remove all packaging before using the mask.
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.
Using your mask
ResMed has tinted the Quattro Air NV elbow blue to identify it as a
non-vented mask.

English 3
The Quattro Air NV has a standard female 22mm tapered fitting for
external connection to the ventilator.
Use a standard conical connector if pressure readings and/or
supplemental oxygen are required.
Fitting
1. Remove the elbow from the mask by pressing the side buttons and
pulling the elbow away.
2. With both lower headgear straps released, hold the mask against your
face and pull the headgear over your head. Ensure that the label on
the back of the headgear faces outwards when the headgear is
put on.
3. Undo the fastening tabs on the upper headgear straps. Pull the straps
evenly until the mask is stable and positioned as shown in the
illustrations. Reattach the fastening tabs.
4. Bring the lower straps below your ears. Loop the headgear onto the
frame and clip the quick release together.
5. Undo the fastening tabs on the lower headgear straps. Pull the straps
evenly until the mask sits firmly on the chin and reattach the fastening
tabs.
6. Start ventilation, then connect the air tubing from your device to the
elbow. Attach the elbow to the mask by pressing the side buttons and
pushing the elbow into the mask.
7. Undo the fastening tabs on the upper headgear straps. Readjust the
straps evenly only enough that a seal is achieved and reattach the
fastening tabs. Overtightening may cause leaks.
8. Your mask and headgear should be positioned as shown.
Removing your mask
There are two ways to remove your mask.
Removing your mask normally
1. Unclip the quick release from the frame by pinching the buttons on
the sides. You can also remove the lower headgear strap from the
hook.
2. Pull the mask away from your face and back over your head.

4
Removing your mask using the quick release cord
1. Pull the quick release cord down. The quick release clip separates
from the mask.
2. Pull the mask away from your face and back over your head.
Disassembly
1. Unhook the upper headgear straps from the frame. There is no need
to undo the fastening tabs.
2. Remove the elbow from the mask by pressing the side buttons and
pulling the elbow away. Remove the elbow from the air tubing.
3. While holding the bottom of the hook, pull the corner of the frame
slightly away from the side of the mask.
4. Remove the frame from the rest of the mask.
Reassembly
1. Press the frame onto the rest of the mask, ensuring it clicks into place
at the top and at both bottom corners.
2. Attach the top headgear straps to the frame by looping through each
of the upper headgear hooks. Ensure that the ResMed logo on the
headgear is facing outward and right side up.
3. If the quick release clip has been removed from the frame, reattach it
by threading it onto the lower right headgear hook.
4. If the quick release has been disassembled, reclip the parts together
as shown in the reassembly illustrations.
5. If the quick release has been removed from the headgear, thread the
lower right headgear strap through the slot on the quick release. Fold
the tab over to reattach.
6. Attach the elbow to the air tubing. Attach the elbow and air tubing to
the mask by pressing the side buttons and pushing the elbow into the
mask. Pull on the elbow to check that it sits securely in the mask.
Cleaning your mask in your home
Your mask and headgear should only be handwashed by gently rubbing in
warm (approximately 30°C) water using mild soap. All components should
be rinsed well with drinking quality water and allowed to air dry out of
direct sunlight.

English 5
WARNING
Always follow cleaning instructions and use mild soap. Some
cleaning products may damage the mask, its parts and their function,
or leave harmful residual vapours that could be inhaled if not rinsed
thoroughly.
CAUTION
If any visible deterioration of a system component is apparent
(cracking, discoloration, tears etc.), the component should be
discarded and replaced.
Daily/After each use:
•Disassemble the mask components according to the disassembly
instructions.
•Thoroughly clean the separated mask components (excluding
headgear), by gently rubbing in warm (approximately 30°C) water
using mild soap.
•To optimise the mask seal, facial oils should be removed from the
cushion after use.
•Inspect each component and, if required, repeat washing until visually
clean.
•Rinse all components well with drinking quality water and allow to air
dry out of direct sunlight.
•When all components are dry, reassemble according to the
reassembly instructions.
Weekly:
•Handwash the headgear. It may be washed without being
disassembled.
Reprocessing the mask between patients
When using between patients, these masks must be reprocessed
according to instructions available on ResMed.com/downloads/masks.

Troubleshooting
Problem/possible cause
Solution
Mask is uncomfortable.
Headgear straps are too tight. The cushion membrane is designed to inflate
against your face to provide a comfortable
seal with low headgear tension. Adjust straps
evenly. Ensure that the headgear straps are
not too tight and that the cushion is not
crushed or creased.
Mask could be the wrong size. Talk to your clinician to have your face size
checked against fitting template. Note that
sizing across different masks is not always the
same.
Mask is too noisy.
Elbow incorrectly installed. Remove the elbow from your mask, then
reassemble according to the instructions.
Mask leaks around the face.
Cushion membrane is creased or folded. Refit your mask according to the instructions.
Ensure that you position the cushion correctly
on your face before pulling headgear over your
head. Do not slide the mask down your face
during fitting as this may lead to folding or
curling of the cushion.
Mask could be the wrong size. Talk to your clinician to have your face size
checked against fitting template. Note that
sizing across different masks is not always the
same.
Frame incorrectly fitted. Remove the rest of the mask from the frame,
then reassemble according to the instructions.
