Before diving with Nitrox, why should divers understand the physiological effects of oxygen?

Understanding the physiological effects of oxygen is crucial for divers using Nitrox because oxygen at elevated partial pressures can lead to oxygen toxicity, which can manifest as visual disturbances, muscle twitching, seizures, or even loss of consciousness. Recognizing these signs and symptoms is fundamental for safety during a dive. Divers must be educated about safe depth limits for specific Nitrox blends to avoid oxygen toxicity, ensuring that they can dive safely and make informed decisions about their dive profiles. Knowledge of oxygen effects also aids divers in planning their dives, understanding their limits, and knowing when to ascend to avoid unacceptable risks. By focusing on physiological effects, divers are better prepared to identify any symptoms of oxygen toxicity early, allowing for timely precautions or responses to ensure a safe and enjoyable diving experience.
