In what condition should a diver consider using EAN32?

Using EAN32, or Enriched Air Nitrox with 32% oxygen, is advantageous particularly for dives requiring longer bottom times because it increases the oxygen concentration in the breathing gas. This higher oxygen content allows for reduced nitrogen uptake during the dive, minimizing nitrogen loading and increasing allowable bottom time while still remaining within safe limits for no-decompression diving.

When diving with EAN32, the increased oxygen helps divers maximize their time at depth before needing to begin their ascent. This is especially beneficial for recreational dives where longer exploration time is desired, such as when observing marine life or exploring underwater environments that may not be accessible on shorter dives.

While EAN32 can be used for shallower dives, there are specific protocols for its use at varying depths, particularly considering the maximum operating depth due to increased partial pressures of oxygen that can lead to toxicity. It is not universally applicable to all recreational diving, as divers need to consider the dive profile and the planned duration, making EAN32 most useful for dives where longer time at depth is a critical factor.
