•Any 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 Quattro if you have ANY adverse reaction to any part of the mask system, 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 Quattro with ResMed flow generators that have mask setting options.
