Allowing adequate time for inert gas elimination through a surface interval is essential before re-diving after a Nitrox dive. During a dive, divers absorb inert gases, primarily nitrogen, into their bodies under increased pressure. After surfacing, the body needs time to safely eliminate the accumulated nitrogen to reduce the risk of decompression sickness (DCS) on subsequent dives. The surface interval allows for the dissipation of these gases, and the specifics can vary based on the depth and duration of the previous dive, as well as the total dive profile. The longer the dive and the deeper the depths, the longer the recommended surface interval generally should be.

Following this practice ensures that divers remain within safe limits and promotes their overall safety during diving activities. Proper understanding of inert gas management is crucial for both recreational and technical divers, as it directly relates to dive safety and the physiological aspects of diving.
