Strange event, no air

[mrtechbench]

There is a gas exhange. The air in my lungs was 32% at start of event, the exchange would have been reduced but not stopped..

Imla:
Question: What was your rationale for not going straight to the surface when you had two failing regs? If you are not breathing, you are not really offgassing either, so a safety stop is neither effective nor warranted? Wouldn't the safer option be to surface sooner?

#####
That was my question too Imla, I wonder how much gas exchange happens when you're not breathing.

I don't think that the amount of offgassing that takes place when you pause on a single breath at 20 feet is significant, but your heart is beating, your blood is circulating, and the lungs are filled with nitrox, so nitrogen should be moving from the blood into the lungs, during the pause.

I think it is analogous to freedivers (who absorb N2 at depth), even though they are not actively moving air in and out of their lungs.

The safe resolution of this failure, is another example (in my mind anyway) of the benefits of freediving and general comfort in the water.

Going too far down that road will make you believe that people who use less air have less chance of the bends if they breathe faster as they come up.
