CNS oxtox is a random event above a ppO2 of 1 bar but can be lessened by relative hyperventilation. It is assumed a diver is largely at rest during deco although Dr Deco recommends cyclical finning at stops to maintain effective tissue perfusion and maximum off-gassing.TwoBitTxn thought I once bubbled...
I always stuck to the 1.4 rule on the bulk of the dive but switched to 1.6 for deco to utilize 100% O2 as there little risk involved and deco is much shorter with 100% oxygen since there is no nitrogen counterpressure.
I am not sure this makes sense. If it takes a certain time for equalisation at the start of any gas change it takes the same time for equalisation at the end of that change. Surely this is just swings and roundabouts since what is taken away at the start must be added at the end?Saturation once bubbled
. . . If we take circulation time as a factor to reduce the total 02 time. . .
However, Saturation, I entirely agree, I think!

Take the 02 breaks to lessen whole body toxcity, add the break time to your 02 time
Here I go, showing my ignorance again. What's a decoweenie. (Indeed what's a weenie?)
