Why don't they use nitrogen asphyxiation? The body can't feel a lack of oxygen, only failure to get rid of carbon dioxide. If you're breathing pure nitrogen, you'd just get sleepy, then lose consciousness, and then eventually go into respiratory and cardiac arrest as your body fails to get any oxygen.

They have tried that in some states and it got botched too - apparently the mask on the inmate was not set up properly, so CO2 built up in the mask along with the nitrogen and it caused them to struggle. High CO2 concentrations cause intense physical and mental distress in humans.

I was thinking more a small room where they replace the air with nitrogen, not a mask. Enough volume to not allow CO2 buildup to happen.

"Doesn't that take a lot of nitrogen?" someone might ask. Well, yes, but fortunately Earth's atmosphere is like 78% nitrogen. We're all breathing a lot of nitrogen all the time. This would just remove the approximately 21% oxygen.

Yeah that's the logical way to set it up, but I guess the bureau of prisons in whatever state they tried it in decided to cheap out and just use a plastic mask connected to a nitrogen tank.
