What is the primary benefit of using Nitrox during diving?

The primary benefit of using Nitrox during diving is the lower nitrogen absorption achievable when compared to air. Nitrox is a blend of oxygen and nitrogen, typically with a higher percentage of oxygen than standard air, which comprises approximately 21% oxygen and 79% nitrogen. When divers use Nitrox, the reduced nitrogen content lowers the diver's exposure to nitrogen at depth. This decrease in nitrogen absorption directly correlates to a reduced risk of nitrogen narcosis and decompression sickness upon ascent.

Using Nitrox can also lead to longer bottom times at certain depths while remaining within safe limits, as the reduced nitrogen allows for more efficient air consumption and decreased decompression stops after a dive, enhancing the overall safety and enjoyment of the diving experience.
