Diaphram
Could we open a discussion about our diaphram. I think mine is not working like it should.
When I get up from my chair, my oxy #'s drop into the 80's. I have been trying to educate myself.
I don't know if this will help but we do have this article on breathing exercises https://copd.net/living/better-breathing-exercises among others. In case it is something you'd like to try - either way, though, there are a few articles that also talk about strengthening your diaphram muscles like https://copd.net/video/three-part-breath Hopefully that at least gives you a place to start. Let us know if there's anything else we can do! Keep on keepin' on, DPM
