Method Partial Hanging + Nitrogen Canister?

[HazelTheGhost]

If I were to do a partial hanging, but use a cpap mask (full face) hooked up to nitrogen canister (compressed with 125 cu/ft & a regulator) to passout with the noose around my neck do you think It'd do the job?

That doesn't sound like a bad idea honestly (unless I'm missing something) if you have a good anchor point + rope I don't see what the issue is. If you passed out long enough the noose should kill you, but there's always a chance of it going awry and you ending up crippling yourself like with a lot of methods. Nooses are hit or miss especially for partial.
