Abstract

The paper concerns a problem of preparation compressed gas mixtures for saturation diving. Obtained results of calculations for helium-oxygen and helium-nitrogen mixtures indicate the recessity of take into consideration the mixing effects of the real gases during preparation of the breathing mixtures. 1 Introduction Using station to underwater investigations and decompression chambers needs proper composition of breathing mixture on certain depth of diving. Precisely determined parameters and properly composed mixture decide on health and often life of a diver who breathes the mixture. At small depth of diving what means low pressure, breathing mixtures act as ideal solutions. In this case according to principle of additivity :
