What
is Nitrox?
Strictly
speaking “nitrox” is any breathing mixture of oxygen and nitrogen,
including standard breathing air (the stuff that covers the planet). Divers
today, however, are generally referring to what is commonly called
“Enriched Air Nitrox” when they talk about nitrox diving. These “EAN”
mixtures contain a higher than normal percentage of oxygen, thereby
reducing the nitrogen and increasing the allowable safe bottom time.
You’ll
remember from your Open Water Diver Class that nitrogen build-up in your
tissues is the factor limiting the amount of time you can stay under water
at a given depth without requiring decompression stops during your ascent.
NOAA
first established standards for EAN breathing mixes in 1978. Mixtures
containing 32% and 36% oxygen (compared to 20% in “normoxic” or standard
air) are called NOAA Nitrox I and NOAA Nitrox II respectively. Subtropic
offers these mixes to qualified divers for use on our dive trips or as tank
fills to take out from the shop.
To
qualify for the benefits of Nitrox diving, special training is required.
Subtropic Dive Center offers a course for $299 to teach about the
limitations and safe use of nitrox. You will learn about the use of special
tables, gas analysis, and nitrox computers, and conduct supervised dives
using nitrox mixes.
