What can be an important consideration when determining dive depth with Nitrox?

When determining dive depth with Nitrox, an important consideration is the potential exposure to nitrogen during dives. Nitrox is a gas mixture that has a higher percentage of oxygen and a lower percentage of nitrogen compared to air. While this mixture can extend no-decompression limits and decrease the risk of nitrogen narcosis, divers still need to be aware of nitrogen exposure.

As divers descend, they absorb nitrogen from the ambient pressure of the surrounding water. The maximum depth that can be safely reached while using Nitrox is affected by the nitrogen content in the mixture. Different blends of Nitrox (such as EAN32 or EAN36) have varying oxygen levels, which can restrict the maximum operating depth to prevent oxygen toxicity. By managing the depth appropriately and considering the nitrogen that can be absorbed during the dive, divers can minimize the risk of decompression sickness and optimize their diving experience safely.
