This anesthesiologist may need some basic chem - N2 does not form ionic
bonds @ ordinary temps & pressures (yes diving P's R ordinary P).  N2 gas
is difficult molecule  to ionize.
So any citations he comes up will B of great interest.

As for aggregability of RBC, platelets & diving, that info goes back to
Pihl (1970's).  It de facto became the progenitor of aspirin as bends
prophylaxis.

The BBA article & subsequent similar papers attempting to dissect the
effects of staright P on RBC's from gas partition we discussed a few
months back.
