This is a Nitrox class for certified divers that covers, in detail, current uses of “back-gas” breathing mixtures with an oxygen content of 32%. Breathing Nitrox allows for extended bottom times and/or a safety margin over air in depths to 100 feet/30m.
The class covers the practical and theoretical aspects of breathing high-oxygen gas mixtures, gas laws and physics, physiology, gas blending and safety, maximum operating depths, “Min-deco” procedures, standard gases and an academic introduction to decompression diving.
The class also addresses gas planning, creating an understanding of “Rock Bottom” or “Min-gas,” which is the amount of gas required to bring two divers safely to the surface from a dive’s maximum depth, in detail.
This is a class that gives the student a practical knowledge and understanding of breathing Nitrox.
