Thinking the strange-to-this-newbie Flow graphs I've been seeing were distorted by ECR3, I set ECR to zero (for the first time) last night. I selected the worst of several resulting examples which I hope will be permitted and shown in my next (8th) post.
As the graphs show, the Flow limitations are not that lengthy, high nor coincident with the sawtoothing and the Leak is moderate.
Yes, it appears that the many top-outs of Respiration
Rates above 50 reflects counting many, maybe all, of the local sawtooth peaks between two successive flow minimums (one "breath").
Using ECR3 my AHI's have been running <1.0 and near or at zero; the related Flow wave forms have a lot of "bumps" but do rise to and fall from a definite maximum in each cycle.
I have a CMS50I on order and am guessing it would have shown a lot of desats last night.
Maybe with this post I'll have 8 posts and will be permitted to (learn and) use appropriate links to Imgur. I hope including the surprisingly large image in my next post will be OK this time
