Hello phishphood:
Arterialization
This was an early question on the Ask Dr Deco forms back in 2000 and 20001. Arterialization of bubbles is a possibility. I tested this in the laboratory with sheep and found no arterialization whatsoever. However, sheep are quadrupeds and are standing when dived in a hyperbaric chamber. Humans dive head down when descending and this changes the hemodynamics [blood flow] of the system. Arterialization could well be promoted in such a case.
Bubble Formation
As answered a decade ago [two are listed in the posters references], surface swims post dive [e.g., less than an hour] can cause bubble formation/enlargement by pressure reduction in small volumes of tissue. The tissue is loaded with nitrogen from the scuba dive and then the diver kicks around on the surface. Strenuous musculoskeletal activity is known from laboratory studies to promote bubble formation.
