[Symptoms] Things are better, but not good enough. Help?

[notausername]

Hello again, esteemed board members 

Things improved a lot since the folks here looked at my graphs and correctly diagnosed positional apnea - I have been working on neck brace choices, still trying a couple Valpeaus

But what's going on is shown in the graph - adding O2 data from O2-Ring Model 3163


At about 06:14 my flow (respiration) stops for 7 seconds, not enough to register as an apnea event.
At 06:17 there's a sudden drop in O2; I have my O2 alarm set to 91%
My HR spikes to 80 in response to the hypoxia, presumably because I have an occluded vertebral artery?
Then at 6:23 there's another spike - I assume because the bump to 80 BPM then drop back to 60 wasn't enough for my brain.
With my HR at 100, I'm jolted awake.

This is serious sh*t; over enough time this kind of thing is sure to screw me up, even if it's not an immediate emergency. This needs to be managed but neuro and sleep doc have been totally unresponsive. It's been going on since March '23

Any ideas? I don't see any event flags other than the O2/HR. C-collar still not working well enough, maybe?

Thanks in advance for any thoughts!

Side note:
I'm really aggravated that sleep docs took a bunch of stats from a healthy population to derive acceptable standards. I should be able to flag 5-second interruptions as apnea if they're going to make my brain hypoxic.


Anyone interested in some advocacy and activism???

Overall, your chart doesn't look that bad based on flow limitations, respiratory rate, tidal volume, etc.  

Notice how the spo2 drop lags behind in time by seconds after the large event you had in the 1st half of this chart.  It takes time for blood to circulate through the body.  

I cannot see any reason why your pulse jumps close to 100 at the end of this chart:  your tidal volume is steady, no major event in flow rate, steady spo2, etc.  Puzzled here.

Hi - thanks for the note. This is what I gather so far:
The flow limit of 7 seconds is what starts the cascade. Note it doesn't show up as apnea, since it's < 10 sec
Then the O2 drop happens, a small spike in HR, then a big spike.

The spikes are a result of brain hypoxia. The O2 drop triggers an autonomic nervous system response from the brain to "dammit hurry up and get some oxygen in here!"

A little scary.

I'm attaching my full sleep session from 3AM to 7AM, in case someone sees something in the overall pattern.

Thanks again for looking! Any ideas welcome.

ugh.
