Looking only at lipid solubility (which I believe is what the table you 
mentioned is based on), O2 should have about twice the narcotic potency 
of N2.  However, real-world factors greatly obscure the actual role 
played by O2 in causing narcosis.  In some cases, (PO2 < ~1.4) it seems to 
cause less narcosis than the equivalent N2.  In other cases (PO2 > ~1.6) 
it seems to be more potent.  A good rule of thumb is to assume it is 
about equipotent for nrcosis as N2.
