Help Pure Nitrogen vs. Pure Helium, which is more effective for CTB?

[Muktar]

Title basically. And how many liters of either one would you need to effectively CTB?

I think both are exactly the same, helium just have more documented case reports. As for the litre i think by calculation you need 10L 200 bar 15 LPM, or a more common one is 9L 137 bar at the same LPM, do cmiiw.

Either…. It's not the gas that kills you….its the lack of oxygen in the environment ( bag or hood) that is created. NB the atmosphere we breath is 90%+ Nitrogen so all your doing is removing the oxygen content.

Would something like this be enough?
