Mirage Micro™
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.
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 cover 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.
