•Any supplemental 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 will vary, depending on the pressure settings, patient breathing pattern, mask, point of application and leak rate.
•The technical specifications of the mask and flow generator are provided for your clinician to check that they are compatible. 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 Liberty if you have ANY adverse reaction to the mask system, and consult your physician or sleep therapist.
•Discontinue using the Mirage Liberty if you experience nasal irritation, and consult your physician or sleep therapist.
•Refer to your flow generator manual for details on settings and operational information.
Using the Mask
Select ‘Mir Full’ or ‘Full Face’ as the mask option when using the Mirage Liberty with ResMed flow generators that have mask setting options.
Fitting the mask
The diagrams in section A on the illustrations sheet show how the parts of the mask fit together.
The diagrams in section B show the suggested sequence for obtaining the best fit and comfort in using your mask. Please follow these instructions carefully.
1Wash your face thoroughly before fitting the mask. It is recommended that you do not apply moisturiser where the mask contacts your face as it can affect the mask seal.
2Place the headgear on your head, like you would a cap, and pull the mask forward onto your face
3Fit the mask over your mouth. Insert the pillows so that they sit gently just inside the entrance to your nostrils.
4Push the lower headgear clips into the slots on the mask frame until they click into place
