What's the theory behind 'bubble pumping' when breathhold diving with residual nitrogen from a scuba dive? From googling forums the common sentiment is that it is a very real danger. One way i am imagining is that breath hold diving actually helps move around nitrogen bubbles which might be stuck or be dissolved in tissue. The moving around might be to the lungs for eventual exhalation (same effect as chamber) or to some other more vital tissue. Unlike a chamber however the pressure is released very suddenly on this sort of ascent.
