Understanding the relationship between EANx (Enriched Air Nitrox) and dive planning is essential because using EANx affects the way divers must approach their dive profiles. With higher percentages of oxygen compared to air, EANx changes the no-decompression limits and the nitrogen absorption rates in divers' bodies. This means that when planning dives with EANx, divers must adjust their profiles to account for these differences, which can include altering maximum depths and total bottom time depending on the specific blend of Nitrox used.

For example, a dive using a 32% Nitrox blend allows for longer bottom times at shallower depths than air, but differs significantly at deeper depths. Without proper adjustments to dive profiles when using EANx, divers could risk exceeding their no-decompression limits, potentially leading to decompression sickness. Understanding these adjustments ensures safety and allows for more extensive dive opportunities while still minimizing the associated risks.
