What is the primary factor to consider in dive planning when using nitrox?

When planning a dive using nitrox, the primary factor to consider is managing exposure to both nitrogen and oxygen. This is critical because enriched air nitrox contains a higher percentage of oxygen than regular air, which alters the physiological effects during a dive.

Higher oxygen levels can increase the risk of oxygen toxicity, especially at deeper depths. Therefore, divers must take care to stay within specific depth limits depending on the percentage of oxygen in their nitrox mix. By effectively managing both nitrogen exposure (to avoid decompression sickness) and oxygen exposure (to prevent toxicity), divers can plan their dives more safely and effectively.

Ultimately, understanding these factors related to gas management is essential for ensuring safe dive experiences while utilizing enriched air nitrox.
