How to fit your mask
Properly fitting your mask is an essential step toward comfortable therapy. ResMed answers your most frequently asked mask fitting questions below.
Q. What's the correct way to fit a mask?
A. Fitting a mask properly depends a great deal on your position. Facial muscles change when we lie down and relax even further once we’re asleep, so it’s always best to fit the mask while you’re in your sleeping position. Whether you sleep in a bed with no pillows or in a recliner, you should fit your mask in your usual sleeping position. If you experience difficulties in fitting your mask, please refer to your mask user guide for complete fitting instructions or discuss it with your care provider or equipment supplier.
Q. How can I keep my mask on at night? I often remove it while I’m sleeping without realizing it.
A. As each individual adapts to their therapy differently, there may be various contributing factors requiring a personalized approach. You should discuss this with your medical equipment provider or physician.
Q. Do I have the right mask size? I have to strap it so tight to obtain a seal that it hurts.
A. It’s important not to over-tighten your mask. Doing so may be a sign that you have the wrong cushion size or an incorrectly adjusted forehead support. If you’re using a ResMed mask that has a MicroFit dial, it’s important to note that your clinician has set the dial at the optimal position and adjusting it significantly from that position may cause discomfort. If you experience difficulties in fitting you mask, please refer to your mask user guide for complete fitting instructions or discuss this with your medical equipment provider or physician.
Q. My mask is leaking. What does this mean?
- incorrect adjustment
- incorrect assembly
- incorrect size
- your mask is worn out and needs replacement
Contact your doctor or equipment supplier to determine which of the above factors is interfering with the proper fitting of your mask.
