Cleaning the Mask between Patients

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, www.resmed.com/masks/sterilization, 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

1Insert the valve into the valve clip (Fig. D-1).

2Push the valve clip onto the elbow (Fig. D-2). Make sure both sides click into place (Fig. D-3).

3Insert the swivel into the end of the elbow (Fig. D-4).

4Insert the assembled elbow (Fig. D-5) into the mask frame.

Mask Reassembly

1Fit 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 the cushion is not twisted or distorted around the clip.

2Align the cushion clip with the mask frame. Push the cushion clip into the mask frame, ensuring that all three clips click into place (Fig. D-7).

3Push the forehead pads firmly into the forehead support (Fig. D-8).
