short answer, read CPAP charts only,
Cpap is your problem get a ASV.
ASV can lower CPAP pressure from 19 to 4.
would you rather sleep with a pressure of 19 or 4?
people with ASV pressure above 4 should change it to 4 as per studies makes no difference.
ask doctor first.

It would help if you could post some charts using sleepyhead. The links for sleepyhead are just below this.

Hello,
In response to Walla Walla, I post charts that match a fairly typical record.
Is that matching with the sleep-wake-junk as quoted by Beej?

I'd like to see the studies you are referring to in regards to pressures not making a difference. Where would they be located? I'm asking, so I can be more informed and to add to my learning.
As for pressures making no difference though, my personal experience says otherwise. For proper therapy for me, I must start at EPAP Min of 9 or I get OSA. In theory, I may try 8 EPAP Min but the machine then has to adjust up when I have events, indicating 9 is closer. But for me personally, I'm not setting my ASV to 4, starving myself of air and making my ASV work harder to always adjust much farther up the pressure scale to a pressure that's more suitable and closer to my 90%.
Not attempting to be offensive or confrontational, but what works for you personally isn't a guarantee that the same applies to everyone else. And yes this does go both ways, my settings may not work for you and your machine nor would your settings be guaranteed good for me.
Happy Friday & weekend to y'all,

The CA's at the end could very well be sleep-wake junk. However you do have a lot of CA's throughout the night. It looks like your on a fixed pressure of 8cm. I don't know if there's an adjustment that can be made. I'll leave that to someone with more background on CA's.
In the future if you could post your charts with the information from the left side also it would help a lot. Check the links below on how to setup the charts.
Thanks and Welcome to the board again.

It’s hard to understand what you’re saying and how the lines relate to each other. It would also help—since data is involved here and offered as fact—if you could say how you arrived at your positions. What “studies” are you referring to?
Could you maybe clarify?

Do appreciate the intent of your reply but as I have no depth of experience with PAP, in my posts, I can only refer to my own experience. Indeed most of us hopefully are adult enough to appreciate individual replies may not apply to everyone else. I have read many many posts to learn from every one's experience and am really happy to report that distilling them for myself and experimentation to discover what suits me has helped me personally.
I am in awe of those who are able to read the data posted and be able to infer best ways forward for others. Not all of us can be in that category.
Thanks for good wishes and of course the same to you too........

In a similar situation. CA's are extremely variable and I can't pin down an environmental cause.
RE: What affects the central apneas ? - E.W. - 11-03-2017
I read an odd article that probably doesn't apply to anyone here. In people who have heart failure and
mixed ca and osa there AHI was a lot better after cardio rehab. And the funny thing is there wasn't much
or any inprovement in there OSA but the CA was reduced a lot it might have been either 40 or 50 %. It
does make me wonder if exercise would help reduce the ca events in us without heart failure.
