Nitrox Diving

Air contains 21% oxygen and 79% nitrogen, and as every diver knows it’s the build-up of nitrogen from that air that usually limits our time under water. Today I did the second dive in my NITROX course, and breathed enriched air with 32% oxygen. The difference is really noticeable after you come up from the dive – you feel a lot less tired, refreshed almost. What a difference a few percentages of oxygen can do!

As a Divemaster you make several dives every day, and it’s good to know how to dive with NITROX since the nitrogen build-up is so much lower than with regular air. Coincidentally, Quo Vadis also just installed a new NITROX blending apparatus today, so I will definitely be testing out new air blends in the future.
