Thanks for responses. Is that like netspeak for "I wish you were dead"? Among the obvious, my wordy efforts are not intended for clinicians like you apparently are. Assumption. As you know, very little attention is given to flow limitation, especially that not flagged by our PAP devices. Assumption...

I have experimented with homebrew tDCS so I am happy with the risk levels involved for myself

That's great, but Ganglion is not tDCS. It's EEG.

Expanded RR Graph, which I think you requested:
15112728-RR.GIF

Actually I NM'ed that, but if you want to pursue that area, put up some 2 minute windows. I think that guy's problem centers around "Sleep Disaster", not "Duty Cycle".

I refer you to your image example from Sat Jan 08, 2022 7:31 am. Obvious severe FL, obvious increasing I-time but a clinically important arousal at 6:57:20.

Now, duty cycle has "dutifully" confirmed what your eyes just saw but I mean like "duh".

Now, my responses will not be quite as thorough as yours because 1. Using something like WordPad prevents post loss but I ain't doing that. 2. Signing up for an image host allows posting of images, but I ain't doing that. 3. Long drawn-out posts provide-- well I don't know what they provide. So I ai...

You asked, maybe challenged: Where I suggested how readers could check their inspiration work time. Actually, that was "where you suggested where", not "where you suggested how". i.e. "ApneaBoard", "cpaptalk", etc. Sorry to be dense. Au contraire, the density is all mine. But at the risk of "doing ...

Meanwhile, I often suggest in posts how sufferers can check their I/E ratios, better yet, convert I and E to duty cycle if they desire and I point out criteria studies and Resmed have shown for assessing duty cycle ratios.

Where? ApneaBoard?

That looks like a pretty busy board.

I need help to understand what you are asking, You mean a 10-20 minute view within bounds of which image? The image posted Saturday? Sorry to be dense. I was referring to Sat Jan 15, 2022 8:51 pm, 8 posts up. Respiratory rate (RR) is set to 13.5 - 17.0 and was looking to change it to 10-20 BPM to t...

FYI if you do decide to go the OpenBCI route, be cognizant that these devices are not FDA cleared.

And you aren't supposed to change your machine settings either!

Aren't we just a bunch of scofflaws!

Also on Saturday's graph, can you change the RR to something a little wider in this example (say 10-20. Play around a little to see what you get)? Right now it looks like the difference of a single breath/minute is a big deal.

Can you highlight those observations that are clinically relevant?

TIA.

Still, the question is whether an inexpensive neural device could add enough data to corroborate breathing-based estimates of time in various sleep stages, particularly if some neural devices claim to calculate this on their own for those without CPAP machines. How inexpensive is "inexpensive"? Wha...

Then there's Muse stuff:

Perhaps... the [defunct] zeo device could capture enough scientific data, particularly in sync with waveform data of breathing (regardless of whether it really has flow rate) to be able to compute things with a greater level of confidence? When did Zeo funct? https://www.amazon.com/Zeo-Model-ZEOBP0...
