Abstract : The decompression sickness is caused by localized gas bubbles in the body tissues resulting from dissolved gas. The basis for a calculation of these bubbles is derived. Only the inactive permanent gases which are not involved in respiration, as e.g. N2, He, are of interest. The bubble grows due to the driving tension of these gases between tissue and bubble where approximately the gas tensions of the surrounding atmosphere exist. The ratio of this tension to the tension in the bubble appears as the governing quantity; its time integral is proportional to the size of the bubble. These considerations are specialized for a simple decompression in three stages and applied to the tables of the U.S. Navy Diving Manual. (Author)
