Intended use
The AirFit F40 mask has two product variants:
- The AirFit F40 variant is intended for single-patient reuse in the home environment.
- The AirFit F40 SLM (Sleep Lab Mask) variant is intended for multipatient reuse in the hospital/institutional environment.
This mask is intended for patients weighing more than 66 lb (30 kg), who have been prescribed non-invasive CPAP or bi-level positive airway pressure (PAP) therapy. The Sleep Lab Mask is the only variant that is validated and intended for multi-patient reprocessing and must be reprocessed if reused between patients.
Contraindications
Masks with magnetic components are contraindicated for use by patients where they, or anyone in close physical contact while using the mask, have the following:
- Active medical implants that interact with magnets (ie, pacemakers, implantable cardioverter defibrillators (ICD), neurostimulators, cerebrospinal fluid (CSF) shunts, insulin/infusion pumps)
- Metallic implants/objects containing ferromagnetic material (ie, aneurysm clips/flow disruption devices, embolic coils, stents, valves, electrodes, implants to restore hearing or balance with implanted magnets, ocular implants, metallic splinters in the eye).
WARNING
Keep the mask magnets at a safe distance of at least 6″ (150 mm) away from
implants or medical devices that may be adversely affected by magnetic
interference. This warning applies to you or anyone in close physical contact
with your mask. The magnets are in the frame and lower headgear clips, with a
magnetic field strength of up to 400 mT. When worn, they connect to secure the
mask but may inadvertently detach while asleep.
Implants/medical devices, including those listed within contraindications, may
be adversely affected if they change function under external magnetic fields
or contain ferromagnetic materials that attract/repel to magnetic fields (some
metallic implants, eg, contact lenses with metal, dental implants, metallic
cranial plates, screws, burr hole covers, and bone substitute devices).
Consult your physician and manufacturer of your implant/other medical device
for information on the potential adverse effects of magnetic fields.
WARNING
- The mask contains safety features, the exhaust vent holes and anti-asphyxia valve, to enable normal breathing and exhaust exhaled breath. Occlusion of the exhaust vent holes or antiasphyxia valve needs to be prevented to avoid having an adverse effect on the safety and quality of the therapy. Regularly inspect the vent holes and anti-asphyxia valve to ensure they are kept clean, clear of blockages and are not damaged.
WARNING
- Only use compatible CPAP or bi-level therapy devices or accessories. The technical specifications of the mask are provided for healthcare professionals to identify compatible devices. Use in combination with incompatible medical devices can decrease the safety or alter the performance of the mask.
- Regularly clean your mask and its components to maintain the quality of your mask and to prevent the growth of germs that can adversely affect your health.
- The mask must be used under qualified supervision for patients who are unable to remove the mask by themselves. The mask may not be suitable for those prone to aspiration.
- Discontinue using or replace this mask if the patient has ANY adverse reaction to the use of the mask. Consult your physician or sleep therapist.
- 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.
- If there is any visible deterioration of a mask component (cracking, crazing, tears etc.) the component should be discarded and replaced.
- The mask is Magnetic Resonance (MR) unsafe and must be kept outside of MRI scanner rooms.
WARNING
- Always follow cleaning instructions and only use a mild liquid detergent. Some cleaning products may damage the mask, its parts and their function, or leave harmful residual vapours. Do not use a dishwasher or washing machine to clean the mask. Ozone or UV light products have not been validated for use with the mask and may lead to discoloration or damage.
- The mask is not intended to be used simultaneously with nebulizer medications that are in the air path of the mask/tube.
CAUTION
- When fitting the mask, do not overtighten the headgear as this may lead to skin redness or sores around the mask cushion.
- Using a mask may cause tooth, gum or jaw soreness or aggravate an existing dental condition. If symptoms occur, consult your physician or dentist.
- The mask should not be used unless the device is turned on. Once the mask is fitted, ensure the device is blowing air to reduce risk of rebreathing exhaled air.
- As with all masks, some rebreathing may occur at low pressures.
- Do not iron the headgear as the material is heat sensitive and will be damaged.
Fitting your mask
Remove all packaging before using the mask.
- Twist and pull both magnetic clips away from the frame magnets.
- Place the cushion under your nose and ensure it sits comfortably against your face. With the ResMed logo on the headgear facing out, pull the headgear over your head. The top headgear strap should sit on top of your head and not too far forward or back.
- Bring the lower headgear straps under your ears and attach the magnetic clips to the frame.
- If the mask needs adjusting, undo the fastening tabs on the upper headgear straps and pull evenly. Repeat with the lower headgear straps.
Mask setting options
Ensure that Pillows is selected in the mask setting options of your ResMed
device. For a full list of compatible devices for this mask, see the
Mask/Device Compatibility List at
ResMed.com/downloads/masks.
Adjusting your mask
-
With the device turned on and blowing air, adjust the position of the cushion for the most comfortable fit under your nose. Ensure that the cushion is not creased and the headgear is not twisted.
-
The top headgear strap should sit on top of your head and not too far forward or back. Reposition the strap if needed to ensure the cushion has a good seal under the nose.
-
To fix any leaks around the nose, pull the cushion slightly away from the face and reposition the cushion so that it sits comfortably under the nose. Adjust the upper headgear straps, if required.
-
To fix any leaks around the mouth, adjust lower headgear straps.
Adjust only enough for a comfortable seal and do not overtighten. -
If you continue to have leaks around the face, you may have the wrong mask size. Talk to your clinician to have your mask size checked. Note that sizing across different masks is not always the same.

Make sure that the vents and anti-asphyxia valves are clean and clear.
Reassembling your mask
- Insert the cushion stud into the frame stud hole. Repeat on the other side.
- Align the vent ring groove against the cushion opening. Press firmly to secure in place and ensure that the cushion opening sits into the vent ring groove.

- With dark grey fabric side facing inwards, insert both upper headgear straps into the frame from the inside and fold the fastening tabs over to secure.
Reprocessing the mask between patients
Only Sleep Lab Mask variants of the mask system are intended for multipatient
re-use. This variant is identified by the “SLM” acronym on the packaging label
and a Unique Device Identifier labeling on the mask.
When using between patients, these masks must be reprocessed according to
instructions available on ResMed.com/downloads/masks.
