What adjustment must be made to a dive plan when using Nitrox compared to air?

When planning a dive using Nitrox, one of the main adjustments is to plan shallower depths for longer bottom times. Nitrox contains a higher percentage of oxygen compared to air, which allows divers to utilize the benefits of reduced nitrogen uptake and extended no-decompression limits at shallower depths. This means that divers can spend more time at these shallower depths while reducing the risk of nitrogen narcosis and decompression sickness.

Using Nitrox provides divers with the ability to extend their bottom times due to the decreased concentration of nitrogen in the gas mix. The principle of allowing for longer dive times at shallower depths takes advantage of the oxygen levels in Nitrox, which are within safe limits for recreational diving. By adjusting dive plans in this way, divers effectively enhance their safety and enjoyment underwater. This thoughtful approach to dive planning is crucial to ensuring divers can maximize their experience while minimizing risks associated with nitrogen absorption.
