Wondering what the yellow and green bands that say Nitrox or Enriched Air Nitrox on a scuba cylinder mean? <\/p>\n\n\n\n
You might even notice that divers using those tanks have taken extra steps before assembling their gear. During the dive, when you are headed upwards to your safety stop, they seem to still have more bottom time left. <\/p>\n\n\n\n
I will explain what Enriched Air Nitrox diving is about so you have a basic understanding of this outstanding tool for a better dive. <\/p>\n\n\n\n
What is Enriched Air Nitrox (EAN) or just Nitrox, is a frequent question from new divers. The answer to that question is fairly simple, however, the reasons behind using it can use some explanations. <\/p>\n\n\n\n
Enriched Air Nitrox is a breathing gas with a higher percentage of oxygen then normal air.<\/p>\n\n\n\n
A Nitrox tank is a dive cylinder filled with an EAN mixture, it has a higher percent of oxygen than what is found naturally in the air we normally breathe. The air we breathe has about 21% oxygen and 79% nitrogen, with a few traces of other gases. EAN-32 is a common blend of Nitrox. It has added oxygen to bring its percentage up to 32%. <\/strong><\/p>\n\n\n\n That means that the nitrogen portion has been reduced to 68%. Since there is less nitrogen going into our lungs, there will be less available to go into our bloodstream as well. This change means that we have a different risk factor than the dive tables will show us using 21%.\u00a0<\/p>\n\n\n\n
