Choosing the right frame size

  1. For male patients, start with the standard frame size. For female patients, start with the small frame size. 
  2. If the frame is too large, try the small size frame for a better fit.
  3. If you try the small frame first and the frame sits too close to your patient's eyes, size up to the standard frame for a better fit.
  4. If the frame is too small, try the standard size frame for a more comfortable fit.

Choosing the right cushion size

  1. Use the provided template to determine whether a patient has a narrow or wide nose. 
  2. If the patient has a narrow nose, place the blue/red side of the template under their nose. If the patient has a wide nose, place the grey/purple side of the template under their nose.
  3. If either the width or length of their nose breaches the margins on the template, size up (to medium or wide).
  4. Select the matching cushion from those provided.

Fitting

  1. Bring the mask above your patient's head and then down over their face while ensuring the elbow is centred on the top of their head.
  2. Place the headgear behind their head and the cushion under their nose. 
  3. Adjust the headgear until the mask and cushion are comfortable.
  4. Disconnect the elbow from the top of the frame and attach it to their air tubing.
  5. Reconnect the elbow with the air tubing to the top of the frame.

Managing leak

  1. Locate where the air is escaping from, which is typically above or below the cushion. Note, there is an intentional vent on the front of the cushion where air will flow through, this is normal. If air is escaping, this is typically above or below the cushion.
  2. Adjust the cushion by gently pulling it away from your face and letting it reseal itself.
  3. Adjust the headgear as needed to achieve a more secure seal.
  4. Check to ensure the frame is secure and that the mask elbow and tubing are not pulling on the mask.

Daily cleaning

  1. Take the cushion off the frame as per disassembly instructions. 
  2. Soak the cushion in warm water and a mild liquid detergent. 
  3. Clean the cushion and its vent holes inside and out with a soft bristle brush. 
  4. Rinse the cushion thoroughly under running tap water. 
  5. Leave the cushion to air dry away from direct sunlight. 

Weekly cleaning

  1. Disassemble the mask into its components as per disassembly instructions.
  2. Soak each of the components (headgear, elbow and frame) in warm water and a mild liquid detergent.
  3. Clean the elbow and frame with a soft bristle brush and the headgear with your hands.
  4. Rinse each of the components thoroughly under running tap water.
  5. Squeeze the sleeves on the frame with a clean towel to remove excess water.
  6. Leave each of the components to air dry away from direct sunlight.

Assembly

  1. Ensure you have all the mask components and parts together. 
  2. Connect the elbow to the frame.
  3. Thread the left end of the headgear into the left side of the frame and fasten the tab.
  4. Thread the right end of the headgear into the right side of the frame and fasten the tab.
  5. Align the arrow on the cushion to the arrow on the frame and connect together.
  6. Connect the remaining end of the cushion and frame together with the ResMed logo facing the right way up through the headgear. 

Disassembly

  1. Ensure your mask is disconnected from your machine.
  2. Pull the cushion out from one end of the frame.
  3. Pull the cushion out from the other end of the frame.
  4. Unfasten the headgear tab from one side and pull it out of the frame.
  5. Unfasten the headgear tab from the other side and pull it out of the frame.
