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.
