Dr. Deco,
Let me start off by explaining I am not a technical diver (no tri-mix, nitrox or deco courses -yet) and this is for information only not actual use.
I am however, a curious engineer who dives a lot. I have been reading a lot on partial pressures and narcosis and am trying to figure out how O2 Narcosis is taken in to account in calculating your END. Can you answer this simply or point me in the direction of a good source. I have figured out that in a tri-mix you can increase helium and decrease nitrogen to make up for the O2 narcosis as well as the nitrogen narcosis; the O2 narcosis is still a mystery to me -not that I fully understand nitrogen narcosis either.
I assume that all gasses are narcotic at some depth depending on how "heavy" (not sure if that is the correct word) they are. Are there equations to figure out narcosis based on this or is it based off some theory and then trial and error?
Thank you,
JSC
