Abstract. Breathing gas mixtures are gaseous mixtures with two or three components, one component being oxygen and the other components being inert gases. These mixtures result from the mixing, in the desired proportion, of two or three of the gases described in the previous paragraphs, one of which is always oxygen. According to the number of main components in breathing mixtures, they are divided into binary (two-component) and ternary (three-component) mixtures. For diving with breathing mixes, account is taken not only of the concentration of oxygen in the mixture but also of the nature of the inert gas in terms of its narcotic effects.
