Manos,

Maybe the problem is your English is a little rusty.  What exactly
do you mean by "Fo2 1.6"?  Are you referring to the fraction of
oxygen in the breathing mix or the partial pressure of oxygen at
a given depth?  FO2 commonly refers to the fraction, not the
partial pressure of a gas.  The phrase "Fo2 1.6" doesn't make
sense.
