Which of the following is a feature of Nitrox diving?

Nitrox diving, which involves using a gas mixture that contains a higher percentage of oxygen and a lower percentage of nitrogen compared to regular air, has several features that make it advantageous for divers. One of the most significant benefits is the reduction of nitrogen absorption in the body during dive activities.

When divers use Nitrox, the higher oxygen content decreases the proportion of nitrogen that the body absorbs compared to breathing air. This is crucial because nitrogen is what primarily contributes to the risks of decompression sickness (the bends). With less nitrogen in the body, divers can have a greater safety margin regarding the decompression process, allowing for longer bottom times and potentially shorter surface intervals, depending on the specific mix used.

By reducing nitrogen absorption, Nitrox diving can enhance safety in terms of decreasing the chance of nitrogen-related issues. This characteristic fundamentally differentiates Nitrox diving from standard air diving, making it an appealing option for those looking to optimize their diving experience.
