Hi All,

If anyone else has any other ideas on what they do to reduce the risks maybe
they will post for all to evaluate.

He was refering (I think) to High PO2s.  When I'm doing an O2 deco
I do one third of the 6m stop at 6m, then move up to 5m.  If it is
a longish deco (>40min on O2) then I move up to 4m after two thirds
of the 6m stop is completed and pull all the remaining O2 time at 3m.

That way only a comparitvely short time is spent at 1.6.  I don't know
how much this would compromise the deco (smaller gradient from bubbles
to blood gas) but then, I run quite conservative decos.  normally ;)

Cheers Jason =:)
