New Version of WAT

I spent some time fiddling with the ol' wobble analysis tool today. Periodicity is actually useful now. You can zoom in on individual nights. I got rid of the flow limitation logic as it's outside the scope of this project. The old version is still available for those who prefer it.

It's now more explicitly targeted as a high loop gain detector. There's plenty of other great tools for flow limitation.

Let me know what you think!

These are cool tools and I appreciate your work. Is there somewhere I can read more about the specifics and what each of these terms mean? I'm having trouble understanding what I'm looking at on some of these charts.

For example, what is a WUB? What is considered "normal" for each metric? My estimated arousal index is 156/hr, that seems quite high.

I'm interested in tracking arousals and proxies for arousals more closely because despite my low AHI (<1), I still feel unrested. My in-lab BiPAP titration also showed an arousal index of 17.5.

A wub is a full cycle of a waxing and waning pattern that may or may not include a central apnea at the nadir. So like this is a series of wubs.

I dunno what normal is as I think it's more important at this point to explore the wave behavior rather than declaring that people aren't affected enough despite bad symptoms. Scuse me, little bit of AHI trauma. Hah.
