Full face mask
Thank you for choosing the AirFit F20. This document provides the user instructions for the AirFit F20 and AirFit F20 for Her masks referred to collectively as AirFit F20 throughout this manual.

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 F20 is a non-invasive accessory used for channeling airflow (with or without supplemental oxygen) to a patient from positive airway pressure (PAP) device such as a continuous positive airway pressure (CPAP) or bilevel system.

The AirFit F20 is:

• to be used by patients weighing more than 66 lb (30 kg) for whom positive airway pressure therapy has been prescribed
•  intended for single-patient reuse in the home environment and multi-patient reuse in the hospital/institutional environment.

WARNING
Magnets are used in the lower headgear straps and the frame of their fit F20. Ensure the headgear and frame is kept at least 2″ (50 mmaway from any active medical implant (eg, pacemaker or defibrillator) to avoid possible effects from localized magnetic field strength is less than 400 mT.

Contraindications
The 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 following a penetrating eye injury.

GENERAL WARNINGS

• 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.
• The mask must be fitted with the supplied elbow (containing the valve and vent assembly) to ensure safe and functional usage unless otherwise specified. Do not use the mask if the valve or vent assembly is damaged or missing.
• The elbow, valve and vent assembly have specific safety functions. The mask should not be worn if the valve is damaged as it will not be able to perform its safety function. The elbow should be replaced if the valve is damaged, distorted or torn. The vent holes and valve should be kept clear.
• The mask should only be used with CPAP or bilevel devices recommended by a physician or respiratory therapist.
• 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 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 venting to allow a 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 holes. When the device is turned off, the mask valve opens to the atmosphere allowing fresh air to be breathed. However, a higher level of exhaled air may be rebreathed when the device is off. This applies to most full-face masks for use with CPAP and 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 the 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.
• The F20 line of full-face CPAP masks is not intended to be used simultaneously with nebulizer medications that are in the air path of the mask/tube.
• 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.

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.
Use a standard conical connector if pressure readings and/or supplemental oxygen is required.

Fitting

1. Twist and pull both magnetic clips away from the frame.
2. Ensure that the ResMed logo on the headgear is facing outwards and is upright. With both lower headgear straps released, hold the mask against your face and pull the headgear over your head.
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. Pull the straps evenly until the mask is stable and positioned as shown in the illustration. Reattach the fastening tabs.
5. Undo the fastening tabs on the lower headgear straps. Pull the straps evenly until the mask is stable and sits comfortably on the chin.
   Reattach the fastening tabs.
6. 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.
7. 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:
   With air pressure applied, pull the mask away from your face to allow the cushion to inflate and reposition onto your face.
   • 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.
2. Adjust only enough for a comfortable seal. Do not overtighten as this may cause discomfort.Removal
   1. Twist and pull both magnetic clips away from the frame.
   2. Pull the mask away from your face and back over your head.

CAUTION
Visible criteria for product inspection: 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:

1.  Disassemble the mask according to the disassembly instructions.
2.  Rinse the frame, elbow, and cushion under running water. Clean with a soft brush until the dirt is removed.
3.  Soak the components in warm water with a mild liquid detergent for up to ten minutes.
4. Shake the components in the water.
5. Brush the moving parts of the elbow and around the vent holes.
6. Brush the areas of the frame where the arms connect, and inside and outside the frame where the elbow connects.
7. Rinse the components under running water.
8. Leave the components to air dry out of direct sunlight. Make sure to squeeze the arms of the frame to ensure that excess water is removed.

Weekly:

1. Disassemble the mask. The magnets can remain attached to the
2. Handwash the headgear in warm water with mild liquid detergent.
3. Rinse the headgear under running water. Inspect to ensure the headgear is clean and detergent-free. Wash and rinse again, if necessary.
4. Squeeze the headgear to remove excess water.
5. Leave the headgear to air dry out of direct sunlight.

Reprocessing the mask between patients

Only Sleep Lab Mask (SLM) variants of the mask are intended for multi-patient re-use. When using between patients, these masks must be reprocessed according
to cleaning and disinfection instructions available on ResMed.com/downloads/masks.
