The correct answer is that Nitrox contains a higher concentration of oxygen compared to air. Standard air is comprised of approximately 78% nitrogen and 21% oxygen, with trace amounts of other gases. In contrast, enriched air Nitrox typically includes a higher percentage of oxygen, which can range from 32% to 40% depending on the specific blend used. This increase in oxygen concentration allows divers to breathe a less nitrogen-dense gas mix, which can help in reducing nitrogen absorption and consequently decrease the risk of decompression sickness during dives.

This higher oxygen content is beneficial for divers as it can enhance safety and extend bottom time at certain depths while allowing for shorter surface intervals. The ability to manage oxygen exposure is critical in diving operations, as divers must remain aware of the potential for oxygen toxicity at greater depths. It’s important to note that the ratios of nitrogen and other gases in Nitrox are lower than those found in standard air due to this increase in oxygen content.
