Specialty Course: Nitrox Diving

Increased Bottom Time & Decreased Risk of DCS

Simply stated, Nitrox is any mixture of oxygen and nitrogen. For example the air you are breathing right now is one form of Nitrox. The term Enriched Air Nitrox describes Nitrox mixtures in which the concentration of oxygen is greater than the 21% present in regular air.

Diving with Enriched Air Nitrox instead of air provides two main benefits: increased bottom time and decreased risk of decompression sickness. SSI's teaching system simplifies learning to use Nitrox. Through the use of special tables complex calculations and difficult formulas are eliminated. The Enriched Air Nitrox course is ideal for the recreational diver who wants to Nitrox dive within the no-decompression limits.

By taking this specialty course, you will learn:

  • Basic physics and physiology of Nitrox
  • How to analyze Nitrox cylinders
  • Planning Nitrox dives
  • How to use dive computers when planning on conducting Nitrox dives
  • Managing exposure to oxygen
  • Gear requirements for diving with Nitrox

Please Note

For this particular specialty you are required to purchase the SSI Enriched Air Nitrox course book, complete the study guide questions, and attend one or two class sessions before doing the dives.
