The investigators hypothesize that membrane microparticles (MPs) are liberated into the blood
stream in response to decompression stress and that certain MPs characteristics initiate
inflammatory responses that contribute to the clinical syndrome the investigators call
decompression sickness. The research goal is to evaluate the number, type and time-course for
elevations in MPs in sport SCUBA divers who present for treatment of decompression sickness.
Blood samples are to be taken from consenting patients before and after they undergo
treatment for decompression sickness and at a follow-up clinic visit from 1 to 3 weeks later
(three samples total).
