Respirator mask for inert gas asphyxiation

[mac_se]

I had the idea of hooking up a respirator to a nitrogen regulator as an alternative to the standard exit bag. It provides an exhalation valve which makes sure CO2 doesn't build up, it would be very secure if well-fitted, and (importantly for me, due to autism sensory bullshit) it doesn't require affixing anything around your neck. There are already 3D printable adapters for filters that could be adapted to accept a hose fitting.

Thoughts? I haven't gotten around to making a mockup yet, but I think it could work pretty well.

I recently had this same idea, and still wondering if that would work.

PAPRs kind of work in similar ways by having a constant flow of air pushed in, but instead of a motor and filter, we have a high pressure tank fitted with a regulator.

I think the main important issue is having an exhaust that is sufficiently large for the gas to carry the CO2 and exhaust out to the outside, otherwise pressure build-up could lift and dislocate your mask with positive pressure while you are unconscious. With flow rate high enough, it could also rupture your lungs.
