How to stop CPAP air leakage through my lips?

by Warren

If you want to stop the CPAP air leaks from your mouth or lips while you sleep, this article will give you some solutions.

I have had my cpap machine for about 3 months...nasal mask seals good but some nights i keep blowing air out of lips even with chin strap on.

As soon as i fall asleep my chin seems to relax and drop and air leaks thru my mouth which causes me to wake again...

I have now tried a full nasal and mouth mask for a trial period but had a real hard time to get the seal to stop leaking...any ideas???


CPAP mask leaks are one of the main reasons for quitting the treatment. However, I can give you some ideas to prevent mouth leaking and lip flutter.

Many CPAP user have to duct tape their lips, seriously, cause they can't think of a better way to stop the leaks.

As an alternative to duct tape - you can use a medical tape called Blenderm by 3M. It is clear, stays put but comes off clean and easily, and does't irritate your skin.

You should leave a 1/2 inch tab turned under and taped together for fast removal just in case.

With the tape I don't think you have to wear the CPAP chin strap. I figure you've got enough crap on your head as it is. However, if it doesn't work, try this method with the chin strap.

A CPAP full face mask, a "hybrid" style mask of nasal pillows and mouth piece (Resmed Mirage Liberty), or a thin layer of PoliGrip Denture Gel is the only viable alternative I know of to stop the "lip flutters" if you don't want to use any of the various taping methods.

You can easily open your mouth with no discomfort if you need to with the thin layer of Poligrip Adhesive Cream and if you do you can easily re-seal your lips by running your tongue lightly over them to moisten them and press them together to re-seal them.

You can also try Poligrip Seal Strips Adhesive for similar results. Since they are made to go in your mouth they won't irritate your lips.

Air Leaking Between Lips During Sleep
by: Ray

I have been using CPAP for aver 12 years and am an "air leaking between lips" sufferer, or used to be! The remedy that works for me is to wear a headband (tennis player type) across my mouth. It needs to be a fairly wide one to ensure it doesn't slip out of position during the night. It also needs to be washed regularly and replaced once the elastic loses tension. I always have at least two on hand to rotate. It provides a soft and comfortable solution, unlike duct or surgical tape, especially if, like me, you have a beard or moustache. The lower strap of my nasal mask helps to keep the headband in position. If using a single strap mask or pillows, it may not be so effective. However, it's an inexpensive option that's worth a try.

have found no tape that works
by: peterp

Even a pinhole leak is enough. Think of a balloon with a pinhole in in it, deflates at once. Have found no solution.

Every tape, including heavy duty industrial, is undermined by saliva and starts leaking within an hour or less. As for full face mask, you the the pressure is equalized, and no problem with air escaping your mouth. But..they leak like crazy!

I had some success with duct tape, but never thought of surgical tape. I will try that tonight.

Glad I finally found a forum that actually helps me!

I use an APAP on 13-20 pressure, nasal mask, 2 chin straps, a Puresleep mouthpiece and earplugs.
