PADI ENRICHED AIR NITROX SPECIALTY COURSE
It's about TIME! This
course is designed to qualify you to use enriched air (“nitrox”)
for no stop recreational diving. The program addresses the use of enriched
air with 22 percent to 40 percent oxygen, with emphasis on enriched
air with 32 and 36 percent oxygen.
The primary purpose of enriched air is to extend your no decompression
limits beyond those of normal air.
The primary goals for this flexible specialty course is to:
- Enable you to plan and make no decompression dives using primarily
enriched air nitrox blends containing 22 to 40 percent oxygen, remaining
within accepted dive table and oxygen exposure limits. You will also
learn some additional material for using enriched air with up to
60 percent oxygen, which is commonly used in semiclosed circuit scuba
for recreational diving.
- Enable you to obtain and care for equipment used in enriched air
diving.
- Enable you to manage and avoid possible enriched air hazards.
- Enable you to use and apply the benefits of enriched air for recreational
diving.
What is Enriched Air Nitrox?
Air consists of approximately 79 percent nitrogen and 21 percent oxygen.
Enriched air has been enriched with oxygen, so it has more than 21
percent oxygen. Enriched air is any nitrogen/oxygen gas blend with
more than 21 percent oxygen.
Enriched air is sometimes called nitrox, which includes nitrogen/oxygen
mixes with less than 21 percent oxygen. These are used by commercial
divers to reduce oxygen exposure when remaining under pressure for
days at a time. For clarity, the terms enriched air or enriched air
nitrox are preferred for the gas blends recreational divers use.
During this course, you’ll be learning to use enriched air with
from 22 percent to the maximum 40 percent oxygen recommended for recreational
diving. You’ll also be introduced to using blends from 41 percent
to 60 percent oxygen, which are common in some recreational semiclosed
circuit rebreathers.
Enriched Air Nitrox is abbreviated EANx, followed by the percent of
its oxygen content. For example, EANx36 is 36 percent oxygen, remainder
(64 percent) nitrogen. In conversation, you would say “EANx36,”“Enriched
Air 36,”“Enriched Air Nitrox 36”or “Nitrox
36.”
