Koh Lanta Nitrox Course

More Oxygen, Less Nitrogen, Less Tired

Feel less tired after diving

Learn to dive with more oxygen and less nitrogen in your tank, with the SSI Enriched Air Nitrox course here on Koh Lanta.

During your Open Water Diver Course, you learned some of the limits of diving on normal air, and how nitrogen affects the body when we go scuba diving.

During our dives, nitrogen is absorbed into our body tissues and this limits our diving depth and time. As you learned in your Open Water Course, too much Nitrogen can be a bad thing.

Diving @ Hin Muang from Koh Lanta with Dive & Relax

Enriched Air gas mixtures contain more oxygen and less nitrogen which means that during a dive, our tissues are exposed to a lower partial pressure of nitrogen. This lower nitrogen partial pressure results in less nitrogen being absorbed by the body during a dive.

As part of your course, you will have 2 dives on 32% Enriched Air Nitrox, that is approximately 32% oxygen and 68% nitrogen.

Many Nitrox divers also claim to feel much less tired after diving on Nitrox, and for those of you who are feeling a little less fit than you used to be, less nitrogen in your body can only be a good thing - especially if you're planning several days diving here on Koh Lanta.

Are you Fit to Dive?

Whilst scuba diving is a very safe activity, it is important to know that you are fit to dive and that you do not have any fitness or medical conditions that could increase your risk of an accident underwater.
