SSI ENRICHED AIR NITROX
1. EAN 32 & EAN 36 The two most commonly used nitrox mixtures in
recreational diving are:
2. Nitrogen The major benefit of diving with nitrox is that it has a
lower concentration of______, which limits our time
at depth.
3. 21% Nitrox and the acronym EANx refer to mixtures with
oxygen concentrations (FO2) higher than:
4. Using the no-decompression limits While diving nitrox, you can improve your safety by:
of an air computer or air tables
5. Nitrox has more restrictive depth Which of the following is true about diving with nitrox:
limitations than air
6. EAN32, EAN36, EAN40 What nitrox mixture can be used at any depth shal-
lower than 99 feet?
7. Ask your SSI Dive Center / Dive Pro- To make sure your personal equipment is suitable for
fessional if your equipment needs nitrox, you have to:
special preparation / modification
8. Deeper A common misconception is that, when compared to
air, nitrox enables divers to dive:
9. Lungs and Central Nervous System Oxygen can be toxic to all body tissues. Its most no-
ticeable and immediate effects take place in the:
10. oxygen toxicity Remaining within the recommended limiting ppO2 of
1.4 ata helps nitrox divers avoid:
11. Pulmonary Oxygen Toxicity (the Lorrain Smith Effect)
poses no real risk to recreational divers because:
