SSI ENRICHED AIR NITROX Question
with complete solution 2023
EAN 32 & EAN 36 - correct answer The two most commonly used nitrox mixtures in
recreational diving are:
Nitrogen - correct answer The major benefit of diving with nitrox is that it has a lower
concentration of______, which limits our time at depth.
21% - correct answer Nitrox and the acronym EANx refer to mixtures with oxygen
concentrations (FO2) higher than:
Using the no-decompression limits of an air computer or air tables - correct answer
While diving nitrox, you can improve your safety by:
Nitrox has more restrictive depth limitations than air - correct answer Which of the
following is true about diving with nitrox:
EAN32, EAN36, EAN40 - correct answer What nitrox mixture can be used at any
depth shallower than 99 feet?
Ask your SSI Dive Center / Dive Professional if your equipment needs special
preparation / modification - correct answer To make sure your personal equipment is
suitable for nitrox, you have to:
Deeper - correct answer A common misconception is that, when compared to air,
nitrox enables divers to dive:
Lungs and Central Nervous System - correct answer Oxygen can be toxic to all body
tissues. Its most noticeable and immediate effects take place in the:
oxygen toxicity - correct answer Remaining within the recommended limiting ppO2 of
1.4 ata helps nitrox divers avoid:
The required exposure time before symptoms arise is well beyond the duration of most
sport dives - correct answer Pulmonary Oxygen Toxicity (the Lorrain Smith Effect)
poses no real risk to recreational divers because:
Multiple ambient pressure (depth in atmospheres or bar) by Fraction of Oxygen (F02)
found in breathing gas. - Bar x F02 - correct answer How can the ppO2 of a breathing
gas be calculated?
1.4 and 1.6 - correct answer The recommended limiting ppO2 and maximum limiting
ppO2 for recreational nitrox dives are:
