CORRECT Answers
What is nitrox? Fraction of nitrogen is reduced, oxygen increased,
also called EANx for example EAN32 (32% oxygen)

excess nitrogen is the cause of ----- decompression sickness
Development of Nitrox began in what year? The same 1908
year the first diving decompression tables were
published

certifications from two specialized nitrox training
agencies
