Anderson5420's OSCAR Data

I have copied and pasted this post into a text document in the CPAP folder on my computer's SD card. Thanks.

Thanks, helpful!

BTW, the link in the Wiki to the University of Chicago page leads to a "page not found" error.

Thanks! Deleted the link.

Today's OSCAR data from last night - both the graphs and the statistics page. Again, the graph shows all CA event flags and no OA event flags. And the statistics page shows an OA index of 0.12 and a Clear Airway index of 7.25. Am I mistaken in thinking that a Clear Airway index is equivalent to Central Apnea event index? Are we all convinced now that my diagnosis of Obstructive Apnea was in error, or do we need more evidence?

So a question occurs: what settings can I change on the Airsense 10 Autoset in the meantime to maximize what it can do for CA, if any?

Thanks.

You had a single OA event flagged just before 2:30.

You had a single OA event flagged just before 2:30.

You are correct, hard to see and I guess I missed it. Does that change anything, and what are your thoughts on my questions if you would care to share?

Oh yippie the purple flags of CA. Yes CA = Clear Airway to the PAP and Central Apnea as the medical term. The historical side shows you've had some elevated CA for a bit. And the AutoSet can be set to avoid CA sometimes, but never can it treat them. Typically the BPAP/bilevel like a VAuto will probably make them go even higher, as in the wrong way. I'll have to look back over the thread to see if we discussed the results from the diagnostic sleep study. As I see it, CA are and have been an issue. The only real fix for CA that will not be avoidable is the ASV.

Attempts to avoid as applicable, CPAP/APAP like AutoSet is to reduce pressure swings as I call it, and that includes No Ramp and no EPR. I know you're already there on settings though. Historical says your CA have been 7.25-10.x during PAP treatment so the avoidance method isn't doing so well. Now it appears most of this thread has been about high CA and the possibility of the ASV.

So back to the diagnostic and titration, both had CA. We must note that CA are consistently inconsistent. A one night sleep study is one sample only and may be a night where CA choose to be lower. And for you the titration was a night they chose to be higher.

My take is bottom line the AutoSet is taking care of everything but CA. This is expected as nothing but ASV treats CA. Unless I'm missing something, CA are currently the only apnea problem and only the ASV takes this case from untreated to treated.

[Sleeprider]

You asked, what can I do to optimize for CA? Dave's answer is pretty accurate, that CPAP does not treat CA events and they will be consistently inconsistent. My only suggestion is to set minimum pressure at 12.0 and maximum pressure at 12.0 to get fixed pressure. That seems to help with CA events for many people. It removes some variables in assessing your PAP therapy. You are looking into movement as a potential root cause, and that may be helpful. In the long run, the only therapy that treats CA is adaptive servo ventilation (ASV). You should contact your doctor informing him that your AHI is unsatisfactory,and describe your symptoms, then request a titration that includes bilevel and ASV to find out what will work for the rest of your life so you don't have to keep dealing with the high AHI and breathing apnea.

I'd agree, the fixed pressure Sleeprider is suggesting is about the only thing left to try. Look at the CA as major QRM and/or QRN and you need to implement the right action to rid yourself of it.

If you're up to it try the fixed 12 and post the OSCAR. Even if you do try it, get your apnea logbook out and keep writing in the current symptoms and complaints on the apnea treatment successes and failures. Make doc aware of this issue.
