PADI, NITROX Exam Questions And
Correct Answers (Verified Answers)
2026/2027
What is "Nitrox"? - CORRECT ANSWER -A gas composed of Oxygen and Nitrogen.
When did you first breath "Nitrox"? - CORRECT ANSWER -Your first breath on this
planet! You breathed Oxygen and Nitrogen
What is "ENRICHED AIR"?
Pg 3 - CORRECT ANSWER -Air that has been enriched with Oxygen.
Air: 21% Oxygen (O2), 79% Nitrogen (N)
What does "EANx 36" stand for?
Pg 3 - CORRECT 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 - CORRECT ANSWER -It exposes you to less nitrogen, which cause DCS.
, What are 3 other advantages of using enriched air?
Pg 4 - CORRECT 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 - CORRECT 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 - CORRECT 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"?
Pg 4 - CORRECT ANSWER -You increase your O2 exposure which can be
SIGNIFICANTLY more hazardous than Nitrogen problems.
How does using enriched air affect NARCOSIS when diving?
Pg 5 - CORRECT ANSWER -NO DIFFERANCE
Theoretiaclly O2 has about the same Narcotic potential as Nitrogen.
