I’m using a ResMed Air10 BiPAP with an AirFit N20 mask (covers just my nose). It took me a lot of trial and error to find a mask that works for me, and I’ve been using the N20 for a couple of years without a problem.

But the last week or two I’ve been waking up extremely tired (as if I hadn’t used my BiPAP at all), with a very dry mouth, and the machine reporting a leak. I suspect I’m for some reason opening my mouth in the middle of the night.

My doctor had once told me about some sort of a strap I can wear around my head to prevent leaks and help keep my mouth closed. Does anyone have any recommendations?

Thanks!
