What strategy can help prevent hypoxia during a dive?

Utilizing enriched air mixtures, such as nitrox, is a strategy that can significantly help prevent hypoxia during a dive. Enriched air contains a higher percentage of oxygen compared to standard air, which can provide divers with a greater amount of this vital gas. By increasing the oxygen content in the breathing mixture, divers reduce the risk of hypoxia, especially during deeper dives where the partial pressure of oxygen decreases due to increased water pressure. This approach allows divers to maximize their oxygen intake, supporting better overall respiratory function and enhancing safety while handling the physical demands of diving.

In addition, enriched air can also allow for longer bottom times and shorter required surface intervals, which contributes to overall planning and safety. Understanding the gas mixtures and their effects on the body is crucial for divers, particularly when considering factors such as depth and duration of the dive.
