Basic Enriched Air/Nitrox Course

For a number of years commercial and military divers have used Oxygen Enriched Air (Nitrox, or EANx) in many of their activities. Nitrox has only recently been accepted for recreational diving use. Along with this acceptance comes controversy. Many divers claim that Nitrox adds safety, and others consider it dangerous. Well, both can be correct, but it is highly dependent on diver behavior. Let’s explore the issues a little. To fully understand Nitrox and its use, you will want to take a Nitrox course or read more about it. I'll try to hit the high points and explain its potential benefits.

Why is it used? Because Nitrox has less nitrogen due to the increased oxygen content, the diver does not absorb nitrogen as quickly on Nitrox as a diver breathing air. This can offer two significant benefits. These are: (1) Less nitrogen absorbed than would have been absorbed using air; (2) Longer bottom time to reach the no-deco limits.  With a lower rate of N2 absorption, divers can extend their bottom times to the no-deco limits.

TDI Nitrox course is an entry level course for divers wishing to utilize enriched air nitrox as a breathing gas. Little else has impacted recreational diving more than the introduction of nitrox, allowing more time underwater. During this course, you will learn the benefits, hazards and proper procedures for diving with EAN 22 to EAN 40 your TDI Instructor will also cover:

• Equipment considerations

• Cylinder labeling

• Analyzing of Nitrox

The course follows an easy to read and understand diver manual titled Understanding Nitrox and water proof tables for quick on site reference.

Upon successful completion of this course, you will be qualified to dive using multiple gas blends up to 40% oxygen.  Additionally, you will be able to enroll in TDI Advanced Nitrox Course and TDI Decompression Procedures Course.
