How should divers handle signs of oxygen toxicity?

Oxygen toxicity is a serious condition that can arise when divers are exposed to high partial pressures of oxygen, which is more likely when using Nitrox or other enriched oxygen mixtures. Recognizing and responding to symptoms of oxygen toxicity promptly is critical to ensure the safety of the diver.

Ascending immediately if symptoms develop is the appropriate response because it helps to reduce the partial pressure of oxygen the diver is experiencing. When a diver ascends, the ambient pressure decreases, which lowers the partial pressure of oxygen in their breathing gas and subsequently lessens the risk of further toxic effects. Delaying ascent could exacerbate any symptoms and lead to more severe complications.

While monitoring symptoms, using safety stops, and notifying the dive master are important points in diving practice, these actions do not take precedence when dealing with the immediate threat of oxygen toxicity. Quick ascent when faced with such symptoms ensures that the diver minimizes the risk associated with oxygen toxicity effectively.
