Did your sleep test show you actually had CAs??? Alot of stuff can show up as CA flagged by the machine that arent.
I still have the occasional CA, nothing to do with pressure. Alot of that is simply your brain and cardio trying to get back in sync concerning O2 levels in the blood after it being disrupted by SA for a period of time before Cpap.
Not a doc but unless your sleep study when your brain waves were being monitered showed you had CAs that is probably all it is.
Your brain senses more O2 than its used too and says ok to much o2 we dont need to breathe.
Then lower 02 blood hits its triggers and it goes ooops breathe. And you do. So your probably not being O2 starved by those CAs. I get em when I know im awake and turned over, didnt breathe as soon as the machine thought I should and it will flag one after pulsing my airway.
I dont get as many as you are though. And yours could be pressue induced. But as another said you need to get the min max spread narrowed first to clear the OAs which are cutting your o2.
Thanks for the replies. Last night was not a good night to base anything on, really. Did not sleep well initially. Sounded like Darth Vader, until I realized the EPR was still set at 3, and was dropping way too much for 8 minimum. Moved it to 1, so when I got up to the 14 range I would get some relief. Was able to have mask a little looser; less pressure, but mask could not handle being bumped when on side. Just got a climateline hose,(thanks, Pugsy), but it is heavier, and I will need to hang it, cause it is hanging off side of bed. Need to do some overall tweeking before screenshots will help.
keep in mind it is also very difficult to ascertain whether changes are working in a single night. You should make your changes and then record a week of data to see the effects and get a coarse tuning, then make a change and record another week. In this fashion you'll be able to have some evidence of what is or isn't working.
If everyone thinks alike, then someone isn't thinking.
Everyone knows something, together we could know everything.
