My breaths looks like this for the majority of most nights. I don't seem to have as many inspiratory flattening except during the first hour of sleep most nights. And then it always looks like this, with the squiggly, flat part on what I think is the exhale?
I've always been suspicious of palatal prolapse, but I don't think I've ever had full blown prolapse in my Oscar data. But does this look like it's partial palatal prolapse?
I always have trouble keeping my mouth shut, and for a couple years I would just sleep with no mouth tape, and sometimes just a cervical collar or chin strap to try to keep my mouth shut, so I still had the option for air to leak out my mouth. But I would often wake up with a dry mouth, and probably experience more disturbances from the mouth leaking. So recently I've tried mouth taping again, and it's been okay but I still feel tired and crappy most days, and I can feel the tape sometimes loosens in the night and I get a dry mouth again. And sometimes my cheeks will puff up if I don't maintain good tongue posture.
So I feel like this all points to some kind of issue with my soft palate. I tried BIPAP in 2020 and it went terribly. I just woke up constantly like every 30-60 mins, with similar settings to the APAP. So I'm wondering if something about that also suggests the soft palate is causing problems that are just made worse by BIPAP, which I've heard can happen with palatal prolapse.
