How long would it take to die breathing pure nitrogen?

Answer 1

Depends entirely on blood O2 saturation prior to exposure to the Nitrogen. Given a 100% Nitrogen atmosphere, the expected time with zero oxygen, starting with a normally O2 saturated victim is about 9 minutes before mortality. However, severe and permanent injury can occur in a shorter timeframe -- as little as 4-5 minutes. Note that extreme hypthermia may cause a significant increase in these times.

Answer 2

There happened a case of Suffocation in Pakistan. The initial info is that. A Long- vehicle carrying a 42Feet Container was accomodated by more than 100 Persons being rided from Afghanistan Border To Quetta ( while travled ~ 75 miles Distance up to Quetta City from the border. Upon reaching to Quette when the container door was opened , it revealed that more than 50 persons found dead due to suffucation. Now the folowing questions arises below. 1.How much the said Vehicle contained Oxygen? 2.In the presence of 100 persons , how much Oxygen being consumed by each person during their detention in Vehicle-Container? 3.If be possible, a formula caluation can be suggested for estimation of Oxygen.

Answer 3

A bit over 4 minutes. Nitrogen is not toxic at normal pressures, it simply does not support life. As the oxygen already in your bloodstream is depleted (and not replaced) you will lose conciousness in about half a minute, and in about 4 minutes, be brain dead.
