How about respiratory minute volume? Of course, also at the surface....Personally I'm not in love with a SAC acronym (and A LOT of other terminology, one can see that pioneers of scuba were not terminilogists ), VR would be better and more sexy (Volumetric Rate), as it's depth independent really and doesn't have to be on the surface.
