What’s the difference between air and Nitrox?
Nitrox, also called enriched air, is a mix of the same gaz but in a different proportion, we enrich the air with extra oxygen so the oxygen proportion is bigger. Its name: Nitrox comes from the combination of Nitrogen and Oxygen.
We refer to Nitrox according to its oxygen percentage, for example a Nitrox 32 contains 32% oxygen and is the most commonly used.
What are the advantages of using Nitrox?
If you remember your Open Water theory class, the amount of nitrogen entering your tissues is what limits the time you can spend at a certain depth.
The more nitrogen in the body, the more we risk a decompression sickness. Using Nitrox allows the diver to have less nitrogen in his blood within a given diving time, which gives Nitrox divers many advantages:
- I’m planning to dive with my friend who dives one air, what’s the point diving nitrox? Even if you follow the same dive profile as air divers, you will be far less tired then if you were diving on air and far safer as you will be further away from a risk of decompression sickness.
- The nitrogen tissues desaturation is what tires you so much after a long dive. The less you have nitrogen in your blood, the less tired you will fill.
What are the disadvantages of using Nitrox?
Can I dive deeper with Nitrox?
The only thing you need to know to dive using Nitrox is that beyond a specific depth, the oxygen becomes toxic. Nitrox being rich in oxygen, it becomes dangerously toxic, faster (less deep) than normal air.
But don’t get scared, after your course, you will know very well what will be your maximum depth on any given nitrox mix and plan your dive accordingly to stay safe!
Can I dive longer with Nitrox?
Where can we dive with Nitrox?
Do I need another certification to dive nitrox?
The Nitrox course is the most taught speciality in the diving industry, not only it is the easiest and quickest diving course, it can be done without even getting wet.
On the MV Smiling Seahorse, we teach Padi Enriched Air Nitrox for 6000 THB. It can be easily done onboard in a few hours but can also be done online before coming through PADI e-learning. Don’t hesitate to get in touch if you have any questions!
