Questions on exit bags

[Adronu]

I am trying to find out the average time to unconsciousness with exit bags depending on gas. trying to see how long it would take to pass out with either helium or nitrogen?

Per the PPH and some other related books, it is pretty fast due to zero oxygen if someone follows the guide correctly. Loss of consiousness should occur in under 10 seconds. Medical journals also support this assertion of it being that fast (see: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9412544/#B24-toxics-10-00424 and also Ogden R.D., Hamilton W.K., Witcher C. Assisted suicide with oxygen deprivation with helium at a Swiss right-to-die organization. J. Med. Ethics. 2010; there are many other med articles/journal entries about it too if you research it a little bit).
