Cheynes Stokes - is that what this screen shot shows?

Thank you both so very much  

I changed pillows and last night was good. Will work on the other adjustments this weekend. I went through my history and it does seem most of these clusters of CA/PB are when falling asleep and close to waking. There was however, this one on the 6/13. Do you think that maybe those clusters had to do with leaks and pressure needing the adjustments?

It still looks to me like you are getting the CA clusters when the pressure rises high.  Not nearly as much with lower pressure.  OA's are dispersed throughout also.  I am awaiting to see if clearing up the positional apnea also clears up the CA's.  I hope all goes well.  Thank you for posting the OSCAR chart.

I’m truly grateful to both of you for your help. It’s been a real relief. Thank you again.
