I don't support capital punishment.
But hypoxia in humans is well studied. Unless they were using monumental stupid gas like CO2 (which triggers your breathing reflex) then the problem wasn't the method, in principle.
I wouldn't put it past a execution supporter to fuck it up somehow, though.
So,.like
was this guy in a relatively large volume chamber/booth and they just trickled the N2 gas in?
If there was enough volume, it could take a long time for the O2 levels to get low enough for him to pass out... BUT does a human body produce enough CO2 to fill that space to the point of triggering the suffocation response? Seems unlikely...
OR did they just strap a rebreather mask to his face and turn on a few l/min?
Were any specifics about the actual setup published?
I don't have any details about the setup but a CO2 concentration of 0.3% would be noticeable. Humans are extremely sensitive to CO2 so it really doesn't take that much to be a problem.
But if he was in something the size of a phone booth (does America have them) then the volume probably is small enough that the CO2 concentration would add up. A breather mask would actually have been better because it would have pulled the CO2 out (they are designed for diving), if they're not going to pull the CO2 out then they need to increase the volume to something the size of a porta cabin.
Hemlock Society recommends an oven roaster bag (like for turkeys) and a bottle of inert gas (usually helium is easiest to get) and just flow enough in to keep the inert atmosphere in the bag "fresh"
Also, there is 'gas stunning' which is used in Europe for slaughter. There are some practices that use CO2 for this, but at a nearly 100% level it is pretty instantaneous, much like HS2 -- which you can't even smell at high concentration, because you're dead already.
Point, there is some state of the art around using gas to kill; it's not a brand new concept.
