Does decompression sickness (the bends) ultimately come from the change in pressure in the lungs, or the actual total ambient pressure over the body?

The solubility of a gas in a liquid is proportional to the partial pressure of the gas above the surface of the liquid Henry’s Law (On the ground at sea level air pressure is about 15psi, nitrogen is ...
