Ok, thank you. Last night was ahi of .11, but it appears to be when I first put on the mask, so I think I was awake. I was able to sleep in one session for longer. Thank you again for your help.
You won't have zeros every night, so don't worry about that

Let's see how it is after a few days, and then see whether a little more minepap would help any.

Ok, thank you. A couple of questions:
1. How long does it take to recover from sleep apnea after it has been corrected? For example, I feel better in the morning, but I still get very sleepy and tired late afternoon (I know my AHI has only been down 2 days...). Also, I was much clearer in thought and speed before apnea. Does that tend to come back?
2. Can you recommend a book, pdf, etc., on how to read sleephead data, apnea terms, general knowledge of apnea, etc., so I can do some analyzing myself. (I will still use you guys and am grateful). I'm a computer guy, so it can be technical. Thank you

My change was immediate. Other people take different amounts of time to feel better.

Some people, forgetting that they've never been that old before, say they never get to feeling like they did when they were younger.

I can recommend the 'pugsy's pointers' post that's at the top of the main page as a starting point for sleepyhead. Then there's a tutorial in the wiki over on apneaboard.

There are no books or PDFs that I know of.

That's funny!

Very good point! I first had apnea when I was 34, now I'm 54! Not likely I will feel like a 34 again. Maybe it will turn into a geezer nap rather than an apnea nap.

However, I hope there will be a great improvement, though. Thank you.

There certainly should be great improvement... though the body is VERY adept at becoming used to whatever's going on as 'the new normal'. So these things become very subjective. But, yeah, you should feel considerably better, over time, than you did before you started this.

Hello,

The new ASV machine seems to have correct my centrals and all other apneas. However, I am only sleeping for about an hour, then awake for 1/2-1 hour, then sleep again for only about an hour, etc.
I'm happy the apnea is corrected, but the lack of decent continuous sleep is killing me. Any suggestions? Attached are two screenshots, one show ahi, the other the broken sleep. Suggestions? Settings changes? Thank you.

You have trouble staying asleep where you wake often during the night for whatever reason. That's called sleep maintenance insomnia.
Do you also have trouble falling asleep at the beginning of the night and going back to sleep when you wake up in the middle of the night?

Any idea why the wake ups?

Do you take any medications of any kind? If so, what?

Any health issues that might be a factor in the wake ups? Pain, other health problems, etc?

I don't think the answer is going to be found in doing little tweaks with the settings. Lots of potential culprits for various insomnia.
Google "sleep maintenance insomnia" and "sleep onset insomnia" and look at all the potential causes and sleep disordered breathing is but one of a long list of culprits.

When did the insomnia start? Before starting cpap or after? What have you and your doctor tried in an effort to reduce the awakenings?

You might want to read this...RobySue mentions a couple of really good books you might look at.

Hello, thank you for the info. Insomnia before? I don't think so, although I haven't slept for more than 2-3 hours at a time for a long time. It's gotten worse since the new machine. I've never had trouble getting back to sleep (that much) before the new machine. Since the new machine, I have a lot of trouble getting back to sleep.

I know it sounds crazy, but I do think that the corrected apnea is something my body is not used to, yet, so I hope the broken sleep improves. Finally having enough oxygen is keeping me awake? Possible?

I am on blood pressure meds and I take benedryl at night to help me sleep.

I'll look into what you said, too.

Thank you for your help.

Sleep maintenance insomnia can be caused by alpha intrusion of delta (deep) sleep. I did a post recently asking for help with this. Did your sleep study mention this at all?

As far as I can tell, XPAP won't solve it, so it's something to look in to.

Hello,

I don't know what "alpha intrusion of delta (deep) sleep" is, nor did anyone mention it to me
I also don't know what xpap is.

please explain.

Thank you

One possible cause is if the asv bursts in pressure (to prevent centrals) is waking me up. Is there any way to change the settings so that the bursts are not so fast and strong, but more gradual? Or another solution? Thank you.

The only thing you can do with the ASV is reduce the max pressure of the pressure bursts by reducing the max pressure support tho may increase your AHI but try a max pressure support of 12 rather than it's current value of 15

I believe it's a poncy way of saying 'disturbed sleep'

x is used in place of other letters, like cpap, apap, bpap.

No way to change the burst unless you limit the burst itself and if you do that you might be not letting the machine breathe for you in the event you have a central apnea and quit breathing. It's that "burst" that makes you breathe and is kinda important.

Those "bursts" of pressure are the machine forcing you to breathe when you don't, that's it's entire purpose. If it doesn't increase the pressure like that, then you don't breathe, and you might as well have a plain cpap, and just have the centrals.
