NITROX UPDATED ACTUAL QUESTIONS
AND CORRECT ANSWERS COMPLETE
STUDY GUIDE
●● What is Nitrox
Answer: Gas mixture with less Nitrogen (usually more Oxygen)
●● Nitrox other names
Answer: Oxygen enriched air, Enriched air nitrox, Nitrox, EANx.
●● "nitrox" can refer to any mixture of nitrogen and oxygen, so plain,
ordinary air would be nitrox, and in the past nitrox has even been used to
refer to nitrogen-oxygen mixtures with less oxygen than air that were
used in undersea habitat diving.
