I’ve been on a cpap since Jan, I’ve also lost about 70 lbs with diet (keto mostly) and the last week I’ve noticed that when I lay down the f30i seems to have trouble venting my exhaled breath until my breathing slows considerably. Specifically when I exhale my next inhale breath is very warm and stale. I noticed that as my breathing slows down this becomes less of a problem, and is non existent when I wake up.
Has anyone else experienced this have a recommendation to deal with this? No changes to my knowledge over the last 4 months, other than weight loss which I wouldn’t expect to contribute to this issue.
