I see a pulmonologist tomorrow. I will keep you posted. Update. I am using an o2 condenser set at 1.5 when I sleep. It seems to be helping. Sleep is better and. Asthma meds are more effective.

Someone mentioned these are our people! I agree! I have the same issues. I requested o2 to protect my other organs at least while I sleep. That helps for nocturnal hypoxia. My daytime drops are Willy nilly like others in these posts. I purchased the O2 ring to prove it! The pulmonologist doesn’t believe the walk of shame with me and all is fine! I do have reynauds but my galaxy watch says the O2 is even worse. I’m getting older so even though I might have had this all my life it’s getting worse. I was tested and they found that I have a PFO . That’s a right to left heart shunt. I was referred to a heart surgeon who the then told me he didn’t think that was the reason. Chech in with him in 6 months. They usually don’t fix this unless you have had a stroke or heart attack. Really!!!!?????
