nasal mask

Thank you for choosing the Mirage Micro™.

Intended Use

The Mirage Micro channels airflow noninvasively to a patient from a positive
airway pressure device such as a continuous positive airway pressure (CPAP)
or bilevel system.
The Mirage Micro is:

to be used by adult patients (>30 kg) for whom positive airway pressure •
has been prescribed.
intended for single-patient re-use in the home environment and •
multipatient re-use in the hospital/institutional environment.

Before Using the Mask

WARNINGS

The vent holes must be kept clear. •
Follow all precautions when using supplemental oxygen. •
Oxygen flow must be turned off when the flow generator is not operating, •
so that unused oxygen does not accumulate within the flow generator
enclosure and create a risk of fire.
At a fixed flow 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.
The technical specifications of the mask are provided for your clinician to •
check that they are compatible with the flow generator. 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 flow generator function.
Discontinue using the Mirage Micro 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 flow generator manual for details on settings and operational •
information.

Cleaning the Mask in the Home

Notes:

The mask and headgear can only be cleaned by handwashing. •
The headgear may be washed without removing the headgear clips. •

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, causing cracks.
Do not iron the headgear as the material is heat sensitive and will be •
damaged.

Daily/After Each Use

To optimise the mask seal, facial oils should be removed from the cushion
before use.
Handwash the mask by gently rubbing in warm (30°C) water using mild soap
or diluted dishwashing detergent.
If the vent requires cleaning use a soft bristle brush.
Rinse all components well with drinking quality water and allow them to air
dry out of direct sunlight. Do not soak the mask.

Weekly

Handwash the headgear in warm (30°C) water using mild soap or diluted
dishwashing detergent. Rinse well and allow it to air dry out of direct
sunlight.

This mask should be reprocessed when used between patients.
Cleaning, disinfection and sterilisation instructions are available from the
