Which gas component does Nitrox contain in higher amounts compared to regular air?

Nitrox contains a higher amount of oxygen compared to regular air. Regular air is composed of approximately 21% oxygen and 78% nitrogen, while Nitrox typically has a higher oxygen concentration, commonly ranging from 32% to 40% oxygen. This increased oxygen content allows divers to enjoy longer bottom times and decreased risk of nitrogen narcosis at certain depths, making it beneficial for recreational scuba diving.

Understanding the composition of Nitrox also highlights the importance of monitoring oxygen exposure and ensuring that divers adhere to appropriate depth limits to avoid oxygen toxicity, which can occur at increased partial pressures of oxygen. The other gases listed, such as nitrogen, carbon dioxide, or helium, are not found in higher concentrations in Nitrox compared to regular air, which further underscores the distinct advantage that increased oxygen offers in this type of gas blend utilized in diving.
