Enriched Air Nitrox
What's Enriched Air Nitrox?
Nitrox refers to any gas mixture composed (excluding trace gases) of nitrogen and oxygen. So, What is the Enriched Air?
Normal air is approximately 78% nitrogen, 21% oxygen, and 1% other gases, primarily argon. Nitrox with an oxygen content above 21% is called "Enriched Air Nitrox".
By the way, "Enriched" means "rich, dense". So, may be understand as "Enriched Air Nitrox is oxygen rich air".
Advantages of Enriched Air Nitrox
So, "Enriched Air Nitrox is oxygen rich air" = "Enriched Air Nitrox is less nitrogen air". Fact that less nitrogen compared to the normal air is that can reduce the risk of decompression sickness. In addition, you can get more the No decompression time.
Can reduce the risk of decompression sickness
You are going to dive for 50 minutes, maximum depth 18 m. In this case, Compare the amount of nitrogen inhale into the body of a normal air and EANx32 (Enriched Air Nitrox 32%).
* Suction amount is 7 liters / min
Use the EANx32,
You can to reduce the about 100 liters of nitrogen.
Can get more no decompression time
The following figure represents the No decompression time of Normal air (21% oxygen) and Enriched Air Nitrox (32% oxygen) at each depth.
|18 m||52 min||77 min|
|21 m||37 min||57 min|
|24 m||29 min||43 min|
Use the EANx32,
You can extend 25 minutes the No decompression time in depth 18 m.
It should be noted, is that can not be obtained two advantages at the same time. The dive at same depth and same dive time as the normal air, risk of decompression sickness because the amount of nitrogen remaining in the body is decreased is low. But, extended the No decompression time must be ignored. On the contrary, you want to use extended the No decompression time, you must accept the risk of decompression sickness same as when using the Normal air.
