Recently mouth is opening during sleep

[vanberg]

I have the ResMed Air sense 10 auto set and use the quatro pro FF mask. I started the Airsense 10 about 3 years ago. Good machine. About 8 months ago I started breathing through my mouth with the morning dry mouth issue. I had a chin strap I had never used so I tried it and it works. I had lost about ten pounds when it started but have gained it back. I still wear the chin strap even though it is somewhat uncomfortable. I place a handkerchief in the chin piece and this helps cushion it.

I like the air sense 10 and have no issues. I recently had a problem with the mask making a whistling noise. I found that raising the tube temperature stopped the noise. apparently I had condensate forming in the tube that was moving to the air vent in the mask. I keep the house temp between 73 and 69 year around. The condensate was forming last winter at the 69 level.

If you are a mouth breather, you need a full face mask.

I am a mouth breather and have pretty much learned to breath thru my nose. My mouth does tend to want to come open so I use a chin strap and cervical collar.

I've used nasal pillows successfully for years but recently I'm waking up several times during sleep because my mouth opens. 

No telling why, but such strange things do happen. You really shouldn't have any trouble transitioning to a full face mask. You will be better rested and will likely wake with fewer marks on your face.

When I was on pain meds Oxynorm over a year ago I started mouth breathing . Even when I got off the drugs it took a few months to get back to breathing through my nose.

I was having trouble getting low AHI numbers even with my higher pressures until I switched from my F-30 to the Wisp.
