Nitrox Certification Exam Review
What is "Enriched Air"? - correct answer Enriched air is any nitrogen/oxygen gas blend with more than 21% oxygen.
What is the Primary benefit of using enriched air? - correct answer Nitrox exposes you to less nitrogen than when you dive with air. (you absorb less nitrogen)
How does using enriched air affect no-stop limits? - correct answer It allows longer no stop limits because you are absorbing less oxygen.
Why is it too simplistic to say that enriched air is safer than air when diving well within no decompression limits? - correct answer Stats for DCI rates with both EANx and Air are virtually the same. Also, reduced nitrogen risk increases oxygen risk, so neither air nor nitrox is safer. Both are dangerous in their own ways.
How does enriched air affect narcosis when diving? - correct answer It does not significantly reduce the narcosis risk because nitrogen and oxygen have the same narcotic potential.
What are the three advantages of using an enriched air dive computer for enriched air diving? - correct answer 1. Computers combine multilevel diving with EANx for the most possible no-stop time.
2. Computers alert for corrective action
3. Simplified dive planning
What is the primary concern regarding EANx and Equipment? - correct answer High oxygen content causes somethings to burn/explode and may cause gear to deteriorate quicker than normal.
What are the requirements for equipment other than cylinders used with EANx up to 40% Oxygen? - correct answer All gear may be used with UP TO 40% oxygen without modification (minus cylinders!)
