Nitrox Diver

This is a 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’/30m. The class covers the practical and theoretical aspects of breathing high-oxygen mixtures, gas laws and physics, physiology, gas blending and safety, maximum operating depths, “Min-deco” procedures, and an academic introduction to decompression diving.

The UTD Nitrox course is normally conducted over a 2 day period, and cumulatively involves a minimum of 16 hours of instruction including academics and two dives. The dives focus on precise buoyancy control and emergency procedures.

This is a class that gives the student a practical knowledge and understanding of breathing Nitrox.
