New, disturbing details have emerged about an incident that got a Kansas sheriff's deputy charged with second-degree murder for the death of a Black man in custody, reported The Guardian on Friday — with the death bearing a striking resemblance to the murder of George Floyd in Minneapolis five years...
Uhm. Ackshally, your body can’t detect a lack of oxygen. In a box with no oxygen, you’d likely just peacefully doze off before you (maybe) die.
What your body does detect is a build-up of carbon dioxide. So if you want to torture someone, prevent them from expelling CO2, or put them in a room full of it.
Edit: for those downvoting, OP is basically describing a Sarco Pod
I used to work at a hospital where we needed to make dry ice to send out specimens. The room the dry ice was made in was basically a closet. Hook the CO2 canister up to this little box thing, take the box apart and boom. Dry ice. More than once I noticed my heart beating fast and I couldn’t catch my breath while making the stuff.
What do you think is filling that oxygen-less box while the person breathes in it?
The atmosphere is about 78% N2 and only 0.05% CO2. So If you took all the oxygen out of a room, it would be mainly nitrogen left, and still only trace levels of CO2.
You will die before you produce enough CO2 to detect.
You actually don’t even need to breathe to do this. If you hyperventilate to expel the CO2 from your blood then hold your breath, you will run out of oxygen before you build enough CO2 up to detect.

Will your body produce CO2 without having oxygen to break down in the first place?
You will have stored some amount of it that you will breathe out.
That’s not enough for your body to detect.
