I wonder if there are lessons to be drawn from other marine mammals which can diver way deeper and longer than assisted humans, although they all also metabolise oxygen. How for example do cetaceans deal with the nitrogen in their bloodstream on returning to the surface?

Marine mammals have evolved adaptations that reduce nitrogen uptake, but there is some evidence to indicate that they do suffer from decompression sickness.
