This study found that there is substantial variability in venous gas emboli (VGE) grades within individual divers after repeated dives on the same profile, suggesting significant within-diver variability in susceptibility to decompression sickness (DCS), and therefore, post-dive VGE grades are not useful for evaluating decompression practice for individual divers.
