Thank you for choosing the Mirage FX. Please read the entire manual before use.
Intended use
The Mirage FX channels airflow noninvasively to a patient from a continuous positive airway pressure (CPAP) or bilevel device.
The Mirage FX is:
- To be used by patients (> 66 lb/30 kg) for whom positive airway pressure has been prescribed
- Intended for single-patient re-use in the home environment and multipotent re-use in the hospital/institutional environment.
WARNING
- The vent holes must be kept clear.
- This 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 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 a risk of fire.
- Remove all packaging before using the mask.
- 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.
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 mask setting options.For a full list of compatible devices for this mask, see the Mask/ Device Compatibility List on www.resmed.com on the Products page under Service & Support. If you do not have internet access, please contact your ResMed representative.Note: If you experience nasal dryness or irritation, using a humidifier is recommended.

The fitting illustrations section in this user guide show the sequence for obtaining the best fit and comfort when using your mask.
Fitting steps
Prior to fitting your mask, remove the elbow from the mask by pressing the side tabs. Connect the elbow to your device air tubing.
- With both lower headgear straps released, hold the mask against your face and pull the headgear over your head.
- Bringing the lower straps below your ears, loop the headgear into the lower hooks on the mask frame.
- Unfasten the Velcro®, pull the upper headgear straps evenly until they are comfortable and reattach the Velcro. Do not overtighten.
- Repeat step 3 with the lower headgear straps.
- Attach the combined elbow assembly and air tubing to the mask by pressing the side-tabs and pushing into mask frame.
- Your mask and headgear should be positioned as shown. Ensure the headgear label is facing outwards.

- Gently separate the cushion from the mask frame.
Reassembly
Refer to the reassembly illustrations in this user guide.
Reassembly steps
- Ensure the cushion is oriented correctly by aligning the top cushion tab with the recess in the top of the mask.
- Gently pull the cushion through the front of the mask frame until the cushion locks securely into the mask frame. The tabs on either side of the cushion should be sitting against the mask frame. Ensure the cushion is not twisted or distorted.
- Attach the top headgear straps to the mask frame by looping onto each of the upper headgear hooks.
- Replace the elbow assembly into the air tubing and attach the combined elbow assembly and air tubing to the mask by pressing the side-tabs and pushing into the mask.
Cleaning your mask in the home
Your mask and headgear should only be gently hand washed.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 86°F/30°C) water using mild soap.
- To optimize the mask seal, facial oils should be removed from the cushion after use.
- Use a soft bristle brush to clean the vent.
- 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
WARNING
Do not use aromatic-based solutions or scented oils (eg, eucalyptus or essential oils), bleach, alcohol or products that smell strongly (eg, citrus) to clean any of the mask components. Residual vapours from these solutions can be inhaled if not rinsed thoroughly. They may also damage the mask.
CAUTION
If any visible deterioration of a system component is apparent (cracking, crazing, tears etc), or, if after cleaning, any component remains unclean, the component should be discarded and replaced.
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.
Troubleshooting
| Problem/possible cause | Solution |
| Mask is too noisy | |
| Vent is blocked or partially blocked. | If the vent requires cleaning, use a soft bristle brush. |
| Elbow incorrectly inserted. | Remove the elbow from the mask and then reassemble according to the instructions. |
| Mask leaks around the face | |
| Mask not positioned correctly | Gently pull the cushion away from the face to reinflate. Reposition your mask according to the instructions. |
| Air leaking around the bridge of the nose. | |
| Mask is not tightened correctly. | Tighten both upper and lower headgear straps. Do not overtighten.Turn off the CPAP or bilevel device and remove mask.

WARNING
- 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.
- 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 devices.
