I haven’t used my cpap in ages. I just took a nap with my nasal mask on (airfit n20). I’m also using a chinstrap that is on pretty tight.
I kept getting woken up by an air sound that seemed like it was coming up somehow. Like an air bubble that wouldn’t come out. Is that a burp that can’t come out because of the forced air flow going down?
It happened several times in an hour long nap.
