Enriched Air Nitrox (EANx) Diver (Nitrox, ISO 11107)

About

This course aims to provide the diver with the knowledge and practices necessary to safely use EANx (Enriched Air Nitrox or NITROX) -- oxygen-enriched air -- as a breathing gas in diving. Upon completion of this course, certified students will be qualified to use EANx (up to EAN40, maximum 40% oxygen mixture) in open water diving activities without direct supervision from an instructor or divemaster, provided that the diving environment, activities, dive areas, and equipment are similar to those used during training.
 
The following topics will be covered in the theoretical classroom sessions (10h): What is NITROX; The history of NITROX as a breathing gas; NITROX myths; Gases and gas mixtures; Diving physiology and NITROX: Nitrogen narcosis, decompression sickness, and oxygen toxicity; Choosing the best NITROX mixture: Maximum Operating Depth (MOD) and best mix; Dive tables and dive computers: Planning using NAUI dive tables for air, EAN32, and EAN36, Equivalent Air Depth (EAD), the rule of halves, and using dive computers for NITROX diving; Oxygen safety precautions and NITROX preparation; Knowing what you breathe: Oxygen analyzers, gas analysis, and cylinder labeling.
 
The following Open Water skills will be reviewed during the confined water practical sessions (5h): SCUBA unit assembly; Water entries: giant stride, side roll, and back roll; Descent; Buoyancy control in a horizontal position (TRIM); Mask clearing; Mask removal and replacement; Regulator clearing; Regulator recovery; Gas sharing; Ascent and safety stop; Water exit.
