Using Nitrox provides a significant benefit in extending bottom time at certain depths due to its altered composition compared to standard air. Nitrox is a mixture of oxygen and nitrogen, where the percentage of nitrogen is reduced in favor of a higher oxygen percentage. This adjustment leads to a decrease in the overall partial pressure of nitrogen when diving, which does not accumulate in the body as quickly as it would with regular air.

At depths within the recreational diving range, divers using Nitrox can reduce nitrogen loading and experience a longer safe no-decompression limit (NDL). As a result, they can extend their bottom time without increasing the risk of decompression sickness, allowing for more extended periods underwater. This advantage makes Nitrox a popular choice among divers who aim to maximize their dive experience while ensuring safety.
