SSI ENRICHED AIR NITROX Question with complete solution 2023
1. EAN 32 & EAN 36 The two most commonly used nitrox
mixtures in recreational diving are:
2. Nitrogen The major benefit of diving with ni-
trox is that it has a lower concentra-
tion 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
of an air computer or air tables your safety by:
5. Nitrox has more restrictive depth Which of the following is true about
limitations than air diving with nitrox:
6. EAN32, EAN36, EAN40 What nitrox mixture can be used at
any depth shallower than 99 feet?
7. Ask your SSI Dive Center / Dive Pro- To make sure your personal equip-
fessional if your equipment needs ment is suitable for nitrox, you have
special preparation / modification to:
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 tis-
sues. Its most noticeable and imme-
diate effects take place in the:
10. oxygen toxicity Remaining within the recommended
limiting ppO2 of 1.4 ata helps nitrox
divers avoid:
11. The required exposure time before Pulmonary Oxygen Toxicity (the Lor-
symptoms arise is well beyond the rain Smith Effect) poses no real risk
duration of most sport dives to recreational divers because:
1/4
