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:

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:

found in breathing gas. - Bar x F02 - correct answer How can the ppO2 of a breathing
gas be calculated?
