Intended Use

The Mirage Activa LT 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 Activa LT is:

•  to be used by adult patients (>66 lb/30 kg) for whom positive airway pressure has been prescribed
•  intended for single-patient re-use in the home and multipatient re-use in the hospital/institutional environment.

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 selection 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.

WARNING

•  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 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.
•  Remove all packaging before using the mask.

Cleaning your mask in the home
Your mask and headgear should only be hand washed by gently rubbing in warm (approximately 86°F/30°C) water using mild soap. All components should be rinsed well with drinking quality water and allowed to air dry out of direct sunlight.
Daily/After each use:

•  To optimize the mask seal, facial oils should be removed from the cushion after use.

•  Handwash the separated mask components (excluding headgear).

•  If the vent requires cleaning use a soft bristle brush.
  Weekly:

•  Handwash the headgear. It may be washed without being disassembled.

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 vapors from these solutions can be inhaled if not rinsed thoroughly. They may also damage the mask, causing cracks.

CAUTION

•  If any visible deterioration of a mask component is apparent (cracking, crazing, tears etc.), the mask component should be discarded and replaced.
•  Avoid connecting flexible PVC products (eg, PVC tubing) directly to any part of this mask. Flexible PVC contains elements that can be detrimental to the materials of the mask, and may cause the components to crack or break.

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

__Mask is too noisy
Cushion clip is not inserted correctly.| Check that the cushion clip is correctly inserted into the cushion, and that the cushion is correctly clipped to the frame.
Ports cap or elbow incorrectly inserted.| Check the the ports cap and elbow are correctly inserted.
Vents are blocked or partially blocked.| Clean vents according to instructions in “Cleaning the Mask at Home”.
__Air leaking around the face
Mask not positioned correctly.| Reposition the mask upon the face.
Air leaking around the bridge of the nose.| Wind the dial in.
