I don't pay much attention to the CNS math (I have yet to find any real
basis for it). However, from my discussions with chamber operators, I am
convinced that air breaks can reduce the probability of convulsion. They
generally use 5 minutes of air for every 20 minutes of O2, so something
on that order of magnitude is probably good.
I would recommend doing the air breaks regardless of what the CNS% clock
says (i.e., don't wait until the clock is full to start them). As for
whether or not to count the air braks as deco time - it probably doesn't
matter a whole lot - either by deco algorithms, or by human physiology.
