PADI, NITROXWhat 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. What are 3 advantages of using an enriched air dive computer for enriched air diving? Pg 5 - correct answer 1) More "No Stop Time" with multiple dives. 2) Alerts you if you exceed Max depth for your blend. 3) Simplify planning & execution while warning you near limits. What is the primary concern reguarding enriched air and SCUBA eguipment? Pg 7 - correct answer High O2 content: 1) Some material may burn or explode. 2) Also may cause rapid deterioration. (Oxidation) What are the requirments and recommendations for SCUBA eguipment used with enriched air with up to 40% O2. Pg 7 - correct answer No answer at this time go look up Why does enriched air diving require a dedicated cylinder? 2 reasons
