What is the primary benefit of using enriched air in diving?

Using enriched air, also known as nitrox, primarily benefits divers by allowing for longer dives, especially at depths where air would limit dive time due to nitrogen absorption. The main characteristic of enriched air is its higher oxygen content and lower nitrogen content compared to regular air. This composition reduces the amount of nitrogen that the body absorbs during the dive, which is critical because nitrogen can lead to the risk of decompression sickness if divers ascend without properly managing their nitrogen exposure.

With less nitrogen absorbed, divers can extend their bottom time within certain depth limits, thereby increasing the time available for exploration and enjoyment of the underwater environment. This allows divers to make the most of their dives without increasing the risk associated with nitrogen accumulation.

While there are other aspects to consider, such as cost, training requirements, and environmental impacts, the primary incentive for using enriched air is its ability to safely increase the duration of dives.
