Lookingforabus put it best when he said:
"Basically, the continuous pressure from the flow of inert gas is supposed to keep air from getting in. Draw the bag tight, but not too tight, AND THE GAS FLOWING OUT KEEPS AIR FROM FLOWING IN." (Emphasis added by me)
The minimum size of tank recommended for this is 20 cubic feet which an SS member named Tiredhorse calculated will give about 40 minutes of nitrogen flow. That's more than enough to induce death.
Nitrogen tanks can also be bought in 40- and 60 cubic feet sizes for an even long flow of nitrogen "just to be sure".
@pane,
i have been reading that "40 minutes" is enough to guarantee death (or CTB) in nitrogen method.
A random question came to mind: is 40 minutes really enough for sure?
If someone finds me at 45 minutes after i go under nitrogen hypoxia, and if the exit bag gets removed and resuscitation attempts (e.g. CPR, rescue team coming, etc.) are made, will that thwart the body from guaranteeing ? Is it possible to suffer from brain damage, if i get resuscitated and then somehow the body is not dead completely (i.e. major organs like heart and lungs somehow recovers from temporary dead state)?
What would be the time duration that would guarantee death/ctb? (i.e. the death of major organs like heart and lung; because brain would die for sure before heart and lung, correct me if i'm wrong)
In other words, question is: For how long not being found would be enough to be completely arrive at death?
I tried checking other threads to find answer to the question, such as: https://sanctioned-suicide.net/threads/i-met-death-today.990/post-11284
I also tried reading a quora article like the following regarding this question:
https://www.quora.com/Can-inhaling-pure-nitrogen-kill-someone-instantly
In that quora article, the most upvoted answer (that quotes
"use Nitrogen safely", Chemical engineering Progress March 2012, p 44–48 ) says about 8 minutes for 100% fatality in 6-8% oxygen environment (which is probably more than the amount of O2 that the exit bag will have after O2 being inhaled or being pushed out by nitrogen coming into the exit bag).
So is a 40 minute really enough for guaranteeing death, based on reading articles & threads like the above ones?
Just trying to mildly question/challenge where the 40 minute time window comes from (i've read about the 40 minute time window, appearing in the first post by
@TiredHorse in the **Exit bag and inert gas megathread**: https://sanctioned-suicide.net/threads/exit-bag-and-inert-gas-megathread.8393/).
I can "feel" that 40 minute is not just a number made up randomly, but just want to see where that number originated from or which rationale brought the time window issue to that number.
If anyone could provide/cite more sources to back up the "40 minute", it would be greatly appreciated.
