Why should you avoid certain activities after diving with Enriched Air Nitrox?

The importance of avoiding specific activities after diving with Enriched Air Nitrox relates directly to managing the risks associated with both oxygen toxicity and decompression sickness. When diving with higher concentrations of oxygen, typically in Nitrox mixtures, the body is exposed to more oxygen than what is present in normal air. This increased oxygen exposure necessitates careful consideration of pre- and post-dive activities to avoid complications.

After diving, the body's nitrogen levels can also be elevated due to the breathing of Nitrox—despite the lower nitrogen content—adjusted decompression guidelines must be observed. Engaging in strenuous activities or climbing to higher altitudes too soon can greatly increase the risk of decompression sickness, as the body needs time to off-gas residual nitrogen safely.

Understanding oxygen toxicity is crucial, as it can occur at elevated partial pressures of oxygen. After diving with enriched air, it is recommended to avoid certain activities, particularly those that could lead to exertion or increase the likelihood of experiencing conditions that exacerbate this risk. Therefore, minimizing exposure to both of these risks ensures a safer experience and aids in proper recovery post-dive.
