Rezumat. Un rol important n conceperea, proiectarea, fabricarea și funcționarea aparatelor de respirație subacvatică l joacă gazele de respirație utilizate n aceste aparate. Tipul de gaz de respirație utilizat este impus de tipul de aparat de scufundare utilizat și de tehnologia de scufundare adoptată. Pentru alegerea corectă a gazelor de respirație n diferitele aparate de respirație subacvatică și pentru stabilirea precisă a tehnologiei de scufundare, este necesar să se cunoască n detaliu caracteristicile fizice ale gazelor utilizate.

Abstract. An important role in the conception, design, manufacture and operation of underwater breathing apparatuses is played by the breathing gases used in these apparatuses. The type of breathing gas used is imposed by the type of diving device used and the diving technology adopted. For the correct choice of breathing gases in the various underwater breathing apparatuses and for the precise establishment of the diving technology, it is necessary to know in detail the physical characteristics of the gases used.

Keywords: diving, gases, breathing apparatuses
