My hypoxia device is fully tested. I would say this is exciting news, but that would be weird. I am satisfied with the device and a bit shocked at how well this method works.
Here are the details. I wore the mask for approximately 3 minutes, in that time my SpO2 (blood oxygen saturation) dropped from 99% to 70%. My O2 level remained at 98-96% until minute 1:30, after that it dropped rapidly. The pulse oximeter I am using was kind enough to alert me (beeps) when the level dropped below 80% I began to feel light headed around at 75% and took the mask off at 70%.
My breathing was shallow and relaxed, the air was starting to get a bit warm and humidity increased to a noticeable, yet not uncomfortable level. This is expected since it's a closed system. The air passing through the soda lime had a slight odor, although it wasn't unpleasant or irritating. I was careful to remove fine particles before loading the device and added a fine mesh filter to remove any stray particles.
Took this photo at minute 2:30, oxygen level at 76% and dropped to 70% 30 seconds later! The right number (82)is my pulse which was around 62 when I started, elevated but not a concern.

* are we really sure the new Debreather is suitable solo, without assistance ?
> I just tested my hypoxia device (aka debreather) and I am personally confident that I can use it solo, although it's impossible to know for sure since there's no way to test past the point of unconsciousness.
* is there a favored body position / setting to undergo, to avoid interference of eventual body convulsions plus object colision so the mask stays still, not hit then displaced after unconsciousness transitioning (that could make death ineffective or worse, brain injury)
> I believe that body position is important, mostly due to movement, not necessarily from convulsions after becoming unconscious. It's probably impossible to predict if a person will have convulsions or how violent they will be.
* for it to be peaceful and reliable, should you prior drug yourself, to experience early sleep in order to avoid distresful symptoms from slow not abrupt O2 drop, or just time stress / second thoughts versus fighting back reflexes ?
> I will probably take Ambien and have a drink or two before. I hit 70% today and was feeling dizzy at the point. It doesn't feel bad. I've been hypoxic before, probably under 70% and started to blackout and saw stars. I would probably lose consciousness at 50-55%.
>> It's hard to imagine a person being able to remove the mask at 6% O2, but who knows as our SI is always at hard work! EDIT: They are referring to 6% available O2 by volume, not not oxygen saturation. A person is typically unconscious under 50-55% SpO2 (oxygen saturation).
