SSI Specialty Course Enriched Air Nitrox (SC-EAN) 40% Level 2 Practice Test

Diving organizations such as PADI, SSI, and NAUI each offer courses that provide training and certification for enriched air nitrox. This means that divers from any of these organizations can receive qualifications to safely dive using nitrox mixtures, which contain a higher percentage of oxygen than regular air.

Each organization has its approach to teaching nitrox, incorporating critical elements such as the benefits of using nitrox in terms of increasing bottom time and reducing nitrogen absorption, along with the associated risks like oxygen toxicity. Hence, any diver certified by PADI, SSI, or NAUI can confidently utilize enriched air nitrox in their diving activities, making the answer inclusive of all the mentioned organizations.
