The management of nitrogen narcosis when diving with Enriched Air Nitrox (EANx) primarily revolves around understanding the gas mixture being used and limiting exposure. Nitrogen narcosis, often described as a state of altered consciousness resulting from the narcotic effects of nitrogen at depth, can be mitigated by recognizing the effects of the nitrogen component in the breathing gas.

Using EANx, which contains a higher percentage of oxygen and reduced levels of nitrogen compared to air, helps in managing narcosis symptoms because the lower nitrogen levels decrease the severity of narcosis at depths where air would become problematic. However, it remains crucial for divers to understand their mix and to limit their exposure time, especially at deeper depths where the effects of nitrogen become more pronounced.

While increasing the oxygen concentration can improve some aspects of diving safety by reducing the percentage of nitrogen, it does not directly address the management of nitrogen narcosis itself. Diving deeper would actually increase the risk of narcosis rather than managing it, and not monitoring depth is contrary to safe diving practices, as awareness of depth is critical in preventing narcosis and ensuring safe dive profiles. Therefore, being knowledgeable about the dive plan and the effects of the gas being utilized plays a crucial
