Abstract

The most likely factor initiating Decompression Sickness (DCS) is believed to be the formation of bubbles in the blood and the tissues. Bubbles form during decompression as a result of supersaturation of the dissolved gas, from the gas nuclei present in the tissues even at normal atmospheric pressure and provoke the symptoms of DCS. Ascent rate is known to be a critical factor for DCS risk. Individual factors, such as age, weight, fat tissues are also recognized for their implication in DCS risk. The aim of this study was to contribute to enhanced safety of divers, by measuring the rate of off-gassing by means of Doppler after decompression and relate it to ascent rate and some individual factors. We showed a clear influence of age and weight on the grades of bubbles. Also, we are making the detections of the grades of circulating bubbles every ten minutes after surfacing, to measure the kinetics of the bubbles. We investigated that bubbles generally peak about 30 ÷ 40 min after the end of the dives.
