There are others on this list with far more knowledge than I, but I
have been told that in determining the narcotic effect of a gas you
must consider its lipid solubility. Oxygen has a high lipid
solubility so therefore is in fact narcotic and should be considered
when determining the END of a mixture. He does not, or is very low,
so not a factor in the calculations. Bill Mee, George or JJ can
answer this one better. My apologies if I have mis-stated anything.
Traditional teachings by the agencies do not account for the O2
content of a mixture in determining the END. This is a mistake. End
of subject.
