TDI Nitrox Diver Course in Playa del Carmen

What is Nitrox?

Nitrox, or Enriched Air, is a type of gas mixture that uses higher concentrations of Oxygen than what is found in the air we normally breathe.  Any air mix with an oxygen concentration higher than 21%, will be considered enriched air.

With this certification, you will be qualified to dive mixes with up to 40% oxygen.

There are many benefits of diving with nitrox. You can extend your bottom time significantly because you are taking in lower concentrations of Nitrogen, you decrease your need for long surface intervals and when used conservatively, diving with nitrox will reduce your risk of decompression sickness (DCS). Mind you, nothing will ever eliminate the risk of DCS other than not diving.

Nitrox does also have some risks due to the higher Oxygen concentrations.  So you should never dive with any mix other than air without proper training.
