Previously discussed?

As in ASV just makes the waveform look pretty.

Or as in the long discussion about Darth Lady's WatchPAT test results starting with your observations about the "ASV Fallacy" and continuing through some breath-by-breath analysis of some of Darth Lady's ASV data and a discussion of the fact that the WatchPAT desats weren't too severe?

Is the data in this thread more of a case of the ASV engineering the wave form to make it look pretty? And if so, how worried should Darth Lady be about it?

I'm not sure what that was. PLMs, maybe? Anyway, we're having a neurologist who specializes in sleep look at Sleep Study No. 4, the retitration study I had about 6 weeks ago, and see if he's got anything to add. I had a lot of PLMs on that study, but supposedly they weren't arousing me. But breathing like I'm having now looks pretty disruptive.

In answer to some of the other questions-

I see you posted this a few months back ->
I too am not a fan of prescription meds, and sadly, I've gone from 0 to about five of them because of one illness, for which sleep apnea may even have been the root problem!
What's the situation today?

And sorry I don't know, but why were you prescribed ASV?
Still on the meds, although I'm going to get off the neurontin to see whether other neurological issues resolve without it. Arixtra (blood thinner), Norvasc (BP), Metformin XR, and prescription folic acid still on the menu.

I was prescribed ASV because I couldn't figure out how to breathe with CPAP, and BiPAP gave me centrals. I failed the BiPAP titration altogether (AHI of 9), so I then had an ASV titration. While the centrals seem to be a consequence of therapy, I'm not sure whether that's purely the case, or whether there would have been centrals had my airway not had the tendency to collapse (you can see some instances of that on the first graph I posted - breathing trailing off, then hypopnea).

PR - Yeah, I figured it wasn't real CSR . While I've got heart rhythm issues, as far as I know I'm not in heart failure and not in the kind of medical situation that would generate real CSR. But having actual periodic breathing get flagged on most nights is a new experience for me.

Again, thanks to everyone for their input!

That would be my guess. If so, then the two or so arousal breaths from the PLMs are interpreted as normal breaths, then the normal compensatory breath reduction is interpreted as a central event, and the ASV decides to try to match the arousal breaths.

Well, I'll make sure the neurologist looks for that. The sleep study report claims I don't arouse, but that's a tech and this will be a doctor. Not that the techs aren't good, but they've got a lot on their plates.
