Method Time needed to guarantee death

[dog3000]

How much time needs to pass before someone discovers the body to be sure they cant bring me back to life? The method is nitrogen.

6 hours is plenty, 12 hours is on the sure side. I see news of ctb bodies found already decomposing, they must have really planned the timing of their deaths really well.

30 minutes to be sure.
