rising central apnea , dropping AHI ....

I have been working on improvement of my therapy for about 1 month..
I've finally got the AHI below 1.0. I was very happy about this .But by some more sturdy on results, I've realized that , there is a rise in CA values which was almost zero when I had larger AHI values.
What is happening ??????????
Is my brain refuses the precautions ?????????
as far as I know hypopnea and obstructive apne are something related with narrowing throat physically. whereas the Central apnea is due to your brain.
So, I solved the problem related with Hypopnea and obstructive apnea by achieving sufficient setting of my Bipap machine.
How can I reduce the CA values ?
Do I have to try some medication ?
Or ,
this is only due to adaptation of my brain to new conditions ???????
does any one have an advice for me ?
Thank you ?

Thank you..

It would really help if you could post your numbers, e.g. how many centrals did you see vs apneas or hypopneas?

I asked the forum almost the same question a few days ago.
This is rested gal's answer, and it was so helpful.

One of my favorite posts by christinquilts is in this topic:
Oct 24, 2005 subject: Central Apnea
viewtopic.php?t=5331

Part of her excellent post:
"Everyone has central apneas- take 3 or 4 very slow & deep breaths right now, then count how many seconds after the last inhale until you feel the need to inhale again. Was it more then 10 seconds? If it was, you just had a central apnea. Next time you sigh take note how long before you inhale again....yep, another central apnea. Yawn? same thing can happen. Pick up a heavy box or weight- did you remember to breath? if you didn't, then you had another central apnea. Think of what you hear exercise trainers lecture about breathing while exercising- its human nature to not breath when we exert themselves.

Of course all of these are awake apneas- but any time you don't breath for 10 seconds, you technically have an apnea. While sleeping, you can have similar things happen- you can take several deep breaths and not need to breath for several seconds."

Jazzer... just sent you a PM..
