Optimization Of Diving With “Nitrox” Over-Oxygenated Breathing Mixtures, To Depths Of 15 ÷ 50 Metres

The efficiency of diving activities carried out by divers should be increased. Improving the efficiency of interventions made with divers at depths greater than 15m has brought into focus the problem of increasing underwater working time by using over-oxygenated synthetic breathing mixtures in order to optimize the relation between working time and duration of decompression. The “NITROX” binary mixture best meets the requirements of diving at depths within the range of 15 to 50 meters. NITROX is used for depths in the range of 15 to 50 m. When this mixture is used, the decompression time shortens and the respiratory resistance decreases. Therefore, the use of NITROX leads to an improvement in diving efficiency, by increasing underwater working time, and by reducing the decompression time.
