| Re: redundant O2
I could run the deep bailout which is tuned to give a decent po2 at depth first in semiclosed and then the shallow bailout (nitrox) in ccr mode when im shallower!
Running the shallow bailout in ccr mode when deep does start to up the n2 content a bit but I would be ascending by then anway and i dont think heliox will offgas you if you have to breathe it OC when shallow |
