I may be off here, but how can SAC be dependent on the tank size? If I breathe .53 c.f. per minute on the surface, I will burn 1.06 cubic feet per minute at 33 fsw, 2.12 cubic feet per minute at 66 fsw, etc. regardless of what size tank I am breathing from. Tank size has zero to do with my rate of consumption, or in figuring what that rate is. Am I wrong?
This is the distinction issue that I got into with several people in the thread I referenced above. .53 cfpm is not a SAC rate, it's actually RMV, Respiratory Minute Volume.
Most seem to disagree with me on the differences between SAC and RMV.
