Proper mask fit is critical to ensuring that the ComfortClassic will meet the patient's needs. Below are some guidelines to follow when fitting a patient with a Respironics Comfort Classic CPAP mask.

Landmarks:

• a.) Sides of nostrils
• b.) Bridge of nose
• c.) Below the nose tip, above the upper lip

Directions:
Begin with the integrated sizing gauge on the package:

• 1. Check landmarks
• 2. Choose the smallest mask that fits without pinching or obstructing the nostrils
• 3. Tighten top straps of headgear, then bottom. DO NOT over tighten straps. Headgear should be secure but not too tight
• 4. Try the mask on with the unit at the prescribed pressure to ensure proper fit

• Final adjustment should be done while lying down with the air blowing at the prescribed pressure through the tubing and mask
• Cushion should not be crushed against the face
• If mask is too tight and causes skin irritation loosen headgear, determine whether mask is stiff from age (if so, replace) or try another size or model
• If leaks are present try loosening the mask or adjusting the forehead spacer, support arm or headgear straps
• DO NOT BLOCK the exhalation port. It is necessary to clear carbon dioxide
• Does not require the use of a separate exhalation device
• Mark the headgear straps with permanent marker to remember where they should be fastened
• Loop the tubing over the headboard to reduce pull on mask
• Remove the mask by pulling over head or use the quick release clip
• To warm the air, place the tubing under a blanket
