manual abstract
If you are experiencing leaks, please ensure that you have followed the fitting instructions carefully. Carry out a quick check after fitting your mask: • Is the mask cushion creased? Creases can allow air to leak out of the mask. • Have you cleaned your mask cushion recently? Oils on the cushion can affect the seal. • Are your headgear straps overtightened? Try not to alter the upper headgear straps once they have been tightened by your clinician. • You may need to slightly adjust the dial. Note the dial setting when comfortable. • Does the mask seem too close to your eyes? You may need a smaller mask. If you cannot resolve any problems, look at the Troubleshooting section, or talk to your clinician. You may require another mask size. Removing the Mask To remove the Mirage Quattro, disconnect one of the lower headgear clips and pull the mask and headgear up over your head. Disassembling the Mask See section C on the illustrations sheet. 1 Detach the air tubing. 2 Unclip the lower headgear clips (Fig. C-1) and unhook the upper headgear straps (Fig. C-2). It is not necessary to remove the headgear clips from the headgear. 3 Remove the elbow assembly from the mask frame (Fig. C-3). It’s easier to pivot the bottom of the elbow away from the mask frame than to pull the elbow straight off. 4 Remove the valve clip from the elbow (Fig. C-4). 5 Peel the valve away from the valve clip (Fig. C-5). Do not pull on the membrane to remove the valve. 6 Detach the swivel from the elbow (Fig. C-6). 7 Note the position on the dial for the next time you use the mask. 4 8 Fully unscrew and remove the dial then pull the forehead support out of the mask frame (Fig. C-7). 9 Remove the forehead support pads from the forehead support (Fig. C-8). 10 Squeeze and push the upper side tabs on the cushion clip out of the mask frame. Pivot away from the mask, and gently pull out (Fig. C-9). 11 Separate the cushion from the cushion clip (Fig. C-10). 12Remove the ports cap from the mask frame (Fig. C-11). 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 optimize 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. Do not twist the valve during cleaning as this may damage or tear the valve membrane or hinge. Take care when handling the valve. 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. 5 Eng Cleaning the Mask between Patients lish The Mirage Quattro should be disinfected or sterilised when used between patients. All components, except the headgear, are validated for up to 20 disinfection or sterilisation cycles using one of the following processes: • Thermal disinfection at a maximum temperature–time combination of 93°C for 10 minutes • Chemical disinfection (eg, Cidex™ OPA or Cidex Plus™) • The STERRAD™ Sterilization System (eg, 100S or NX). The headgear should be thoroughly washed between patients, as described in “Cleaning the Mask in the Home”. Detailed disinfection and sterilisation instructions are available from the ResMed website, and must be consulted before multipatient use. Reassembling the Mask See section D on the illustrations sheet. Before reassembling the mask, check that all components are clean and dry. Check that the valve is not damaged, distorted or torn, and that none of the other components are broken or cracked. Replace any parts that are damaged. Flexible PVC contains elements that can be detrimental to the materials of the mask. If flexible PVC tubing is used continuously, the attachment port should be inspected for cracking. Replace any parts that are damaged. Elbow Reassembly 1 Insert the valve into the valve clip (Fig. D-1). 2 Push the valve clip onto the elbow (Fig. D-2). Make sure both sides click into place (Fig. D-3). 3 Insert the swivel into the end of the elbow (Fig. D-4). 4 Insert the assembled elbow (Fig. D-5) into the mask frame. Mask Reassembly 1 Fit the cushion clip into the grooved edge of the mask cushion. Fit the top section first, then work your way around, pushing the clip into the cushion (Fig. D-6). Ensure that ...
