The clock only seems to apply to PO2s that are higher than any of us should be breathing in the first place. Also, I modify my deco tables so much that I am virtually ignoring them anyway. > > Second sat divers are more concerned with pulmonary/whole body toxicity that > CNS problems as they are either in surface supplied or in a habitat where > the cns problem is not a risk.
