Why must divers understand the concept of "depth correction" when using EANx?

Understanding the concept of "depth correction" is crucial for divers using Enriched Air Nitrox (EANx) because it directly relates to managing oxygen exposure and ensuring safety during dives. EANx typically has a higher percentage of oxygen than regular air, which means that the partial pressure of oxygen increases as the diver descends to greater depths.

This increase in partial pressure can lead to a higher risk of oxygen toxicity if the limits are not understood and respected. By applying accurate dive profiles that include depth corrections, divers can stay within safe operational parameters and avoid exceeding their oxygen limits. This awareness helps divers to manage their exposure effectively, plan their dives better, and ensure a safer overall diving experience.

Other options do not relate directly to the primary concern of managing oxygen toxicity through understanding depth correction, which is the main focus of safety when diving with EANx.
