Thanks to Maria and David for pointing this out.

As guidance on how to determine appropriate treatment, the same issue of
AquaCorps also has a long article that describes the USN Treatment
tables, with graphs of what the treatment sequences are, together with
information on how to best decide on the most appropriate treatment
sequence and starting point.

David raised a further issue: that of how far are you from a
recompression chamber?  In Monterey, CA, you may well have access to one
within the hour.  Here in New England, you'd be lucky if you get to one
within 6 hours.  If you're diving in or around Boston, the nearest
chamber is in Groton, CT, which is 2-3 hours drive away.  Add to that
the time to decide you need it, plus the time to mobilize the chamber
staff, plus the time to get back to shore, and you have a lengthy
journey. And, on top of that, rumor has it that the latest round of Navy
facility closures will close this chamber.  So, as a New England Diver,
you need some alternative.

I agree that in-water recompression is a complex and difficult subject.
However, I also believe that for the diving I do, it is important to
have this possibility as an option, given the lack of alternatives.
This means making the effort to learn more about the subject, as well as
bringing along the equipment I may need, should some form of treatment
become necessary.
