Method How much time does it take to die with Nitrogen method?

[randomsomeonein]

I am choosing nitrogen method. I know that we become unconscious within a min but I don't know how much time does it take to die with that method.

Please help.

Around 10-15 min, brain damage occurs after a few minutes.

Unconsciousness typically comes in less than 20 seconds in a few breaths. Then maybe death in 10 minutes or less.
