Insert gas test with video. 98% SP02 to 35 in 14 second

[Msvr]

Earlier today I did an experiment. I filled my exit bag with N2 and filmed myself, planning on doing the blackout test. After 3 breaths and about 15 seconds my blood oxygen levels started plummeting from 98% to 35% in 14 seconds. So in 29 seconds total I dropped to 35% SP02. I then backed out before actually blacking out, but obviously one more breath would have done it for sure. I also didn't even hyperventilate, or deeply exhale before the test. If I had done those I probably would have passed out in sub 30 seconds. Zero discomfort, headaches, or anything. I just as rapidly increased back to 99% when I started breathing oxygen again. Here's a quick 14 second video of my finger oximeter showing the plummet. Sorry for the quality, it's highly zoomed in:

Did you make your own exit bag?

Did you make your own exit bag?

Yeah, just a classic bag as described in the PPH or doing it with Betty/chi videos

Oh wow. So you weren't planning on actually doing it yet at this point, correct? Any feelings of SI?

Yeah this was just a test, not an actual attempt to CTB. I just breathed the N2 through a tube I stuck in the exit bag. And due to that there weren't any feelings of SI. When I actually do CTB though I have wrist straps. If SI does kick in those will make it harder to change my mind. Also prevent my hands from doing anything after falling unconscious

I think it is fake, because oxy pulse meter itself take 10 second show reading, and it never down during breath holding than how it is down in nitrogen environment, it is not atmosphere oxymeter
