ENRICHED AIR NITROX UPDATED ACTUAL EXAM
QUESTIONS WITH VERIFIED ANSWERS (2026)
●● When did you first breath "Nitrox"?
Answer: Your first breath on this planet! You breathed Oxygen and
Nitrogen
●● What is "ENRICHED AIR"?
Pg 3
Answer: Air that has been enriched with Oxygen.
Air: 21% Oxygen (O2), 79% Nitrogen (N)
●● What does "EANx 36" stand for?
Pg 3
Answer: Enriched air Nitrox 36%
Can be called:
1) EANx36
2) Enriched Air 36
3) Enriched Air Nitrox 36
4) Or, Nitrox 36
, ●● What is the primary benefit of using enriched air?
Pg 4
Answer: It exposes you to less nitrogen, which cause DCS.
●● What are 3 other advantages of using enriched air?
Pg 4
Answer: 1) Extends allowable bottom time.
2) Reduces need to "Push" air No Decompression Limits.
3) Reduces overall Nitrogen load on multiple dives.
●● How does using enriched air affect "No Stop Limits"?
Pg 4
Answer: Longer "No Decompression Limits. Less Nitrogen in body.
Body metabolizes the extra O2.
●● How does using an "Enriched Air Computer" affect your "No Stop
Limits"?
Pg 4
Answer: Used with "Enriched Air Computer" you have even longer No
Stop Limits.
●● Why is it wrong to say, "enriched air is safer than air when diving
well within Air No Decompression limits"?
