Thank you all for your answers. I have not been tightening the chin strap for comfort reasons. I’ll tighten it tonight and see if that makes a difference.

The ring monitor looks interesting. I’ll think about that.

Tightening the chin strap usually does work. I also bring a couple of feet of tubing in the bed with me in case I roll over during the night. Keeping slack in the line helps stop the cannula from coming out of your nose. Another trick might be to use a small amount of medical tape to hold the cannula on your cheeks or slightly alongside the nostrils. Good luck with rectifying the issue, Heather.

Hi Heather, I have to tighten the tubing a little under my chin, make sure you are not pulling the tube out with your body when turning over. Is there a facial tape for sensitive skin that you might can hold it in place, someone had suggested that when I first went on oxygen. I go from my back to my right side at night, I try to keep the tubing above my shoulder so I don't accidently roll on it and pull it out of my nose.

I sleep all different ways and haven't had this problem. I also get up quitte often for pee breaks. Are you tightening the chin strap tight enough?

I sleep on my sides at all times. I have had good luck w/ canula going around ears & staying in place. There have been a few times (can count on 2 hands) that the canula has slipped off during the night, but not often. The canulas I use also have that little adjustment piece where you can tighten it up around the chin, which holds it in place. I don't care for that adjustment piece myself. (could be why my canula comes off all the time ie: daytime)
