Part of the issue might also be that they just used a cheap one size fits all mask instead of something that took a modicum of fucking effort. Nitrogen asphyxiation is used in parts of Europe for medically assisted suicide, so it can be done humanely, but the procedure requires more than just slapping something you ordered on Amazon on a guy’s face and calling it good. Of course, the people undergoing it in Europe have also chosen to die, and aren’t struggling to hang on for ten more seconds. Fuck this place.
