What is a potential risk when diving with higher oxygen levels?

Diving with higher oxygen levels can lead to oxygen toxicity, which is a significant risk associated with enriched air diving. Oxygen toxicity occurs when the partial pressure of oxygen in the body exceeds safe limits, leading to potentially severe physiological effects. Symptoms can include visual disturbances, seizures, and in extreme cases, loss of consciousness, which can be life-threatening underwater.

Understanding oxygen toxicity is essential for divers using enriched air, as it emphasizes the importance of adhering to recommended depth limits and managing exposure times based on the percentage of oxygen in the breathing gas. This helps ensure safety and minimizes the risk of adverse effects during dives.

While other options may represent aspects relevant to diving, they do not reflect the direct risks posed by elevated oxygen levels as accurately as oxygen toxicity does.
