Hello,
I often breath 100% oxygen at 5m (20 feet PPO2 1.5) to enhance offgassing. My hang time at 5 m is usually 5 minutes and I then proceed to 3 m (10 feet) an do an additional 2 to 3 minutes before surfacing. This is not decompression, but rather safety stops from no decompression dive.
My question: Is there much beneifit in the 3 m (10 feet) hang considering the 100% oxygen would be creating a very large pressure gradient for elliminating nitrogen??
There probably is not much data on this - I don't know. I guess I'm curious as to the benifit/ lowering of DCS risk with the addition of the 3 m hang in comparison to doing only a 5 m hang. Is the 3 m hang really helping to ellimate the nitrogen or is it just marginal in its beneifit?
Perhaps it is better to only to the 5 m stop then surface?
As always - thank you................Iain
