dc.description.abstract The growth dynamics of gas bubbles has been generally modelled and can be applied to situations such as decompression, flying after diving and diving at altitude. Evolution of the gas volume contained in a bubble nuclei distribution is determined from the ambient pressure-time relationship, diffusion, permeability of gas/medium interface and surface tension. The distribution characteristic is inferred from the upper tail measurements under atmospheric conditions and theoretical considerations. The gas volume of bubbles at ambient pressure is evaluated from the atmospheric distribution. The new estimated distribution gives significantly increased bubble gas volume compared to previously proposed distributions. The theory predicts that the initial rate of decompression should be higher than USN tables, and that the final rate at apx. 50 msw and shallower should be less. Total decompression time can be shorter. Flying at apx. 0.75 bar immediately after saturation decompression makes the bubble volume continue to increase more than twice the excess volume at arrival at the surface. When diving at altitude, apx. 2000 m, a sea-level decompression may increase the excess bubble volume apx. fourfold compared with the corresponding sea-level decompression. en
