First, I am not a Trimix diver nor am I planning on doing it (too much time, money and trouble for me) but I had a question about its use.
I understand that the idea is to reduce oxygen toxicity by reducing the % of O2 in the mix and to reduce nitrogen narcosis by reducing the % of N in the mix. (He) is then used as a filler (correct me on any of that if I am wrong).
So, and my numbers should not be taken literally as I have no idea what a valid mix is, say for example you have determined that you need 10% O2 and you put in 15% N so you would then add 75% (He).
Why would you not do 10% O2 and 90% (He) and just forget about the N as I donÃÕ see how it helps at all. I know there must be a valid reason for the Nitrogen but could someone explain it to me please?
