Intravenous Gas Emboli in Man after Compressed Air Ocean Diving.

Abstract : Non-symptomatic venous gas emboli (vge) in man after ocean diving was studied with the Doppler 'Bubble Detector.' Curves of vge score post-dive after several dive profiles is presented. The relationship between at-depth exercise and post-dive vge was studied. Lower levels of vge were found with moderate exercise underwater than with either resting or heavy exercise. Exercise-induced perfusion increases during diving can increase N2 uptake and, thus, vge formation.
