Following advice from SB, I ordered a copy of Tom Mount's mixed gas diving encyclopedia, and I've read it with great interest. I understand that this book is quite popular, and Tom gained much respect in the community. In the final chapters, the book introduces the Arterial Bubble Model, apparently in the making for 20+ years, tested during commercial diving operations, and published in tables. The claims in favor of the model sound pretty attractive. A quick search on Google, and then narrowed to scubaboard.com, seems to suggest that this theory has not gained much adoption (the papers also have very few citations). Or has it? What happened to it? Are its assumptions inaccurate, claims still unproven, or has it been superseded with something even better?
