Pressure support induced CAs -- anyone try Diamox ? Other solutions ?

[foxfire]

no matter, but I was not commenting on the (age of the) 1982 citation. by 'ancient history' I was referring to my 1987 experience.  I have no idea if 1982 info (or 2009) is current or outdated.

good to have the additional references in any event.

oops, sorry, was trying to respond to ycsi.

Thanks everyone for the help on this, great articles / sources, really appreciate it! 

Hope no one's getting tired of my threads -- I'm taking a month off and trying something new every few days to FINALLY (3 years on cpap and trying everything under the sun) get some better results and get rid of my chronic fatigue.. 

And apologies, I may have posted unnecessarily -- after more research, I think the 'CAs' aren't real centrals. Rather SWJ, and or OA. 

They typically are preceded by unstable breathing and probably an arousal. Sometimes a big inhale (last picture), which is why i thought they were CAs -- thought I was flushing out too much CO2, causing 20+ second pauses in breathing. 

But now I think they're mostly OAs.

I think we need to go back to the fact your CAI is about 1, which is not a problem, and is well within normal for most of us. Your events seem to be mostly preceded by a sigh or other respiratory disruption suggesting this is nothing more than a sleep transition, position adjustment or similar normal sleep event which can result in an event being recorded. When CA is a concern, it involves long clusters of apnea and a CAI generally well over 5/hour.

You are becoming accustomed to pressure support, and it would be normal to experience a few more CA under those circumstances. Your rate is so low, and the events randomized in a way it should simply not be a concern at this point. Relax and work with it, but you don't have a central apnea problem.

How about "clinically insignificant"?
