Why is it important to analyze the oxygen content of Nitrox before a dive?

Analyzing the oxygen content of Nitrox before a dive is crucial to ensure that the desired gas mixture is used. Diver safety is highly dependent on the specific blend of oxygen and nitrogen in the gas mixture. Each blend of Nitrox has a maximum operating depth that corresponds to the percentage of oxygen in it. If the oxygen content is too high, it increases the risk of oxygen toxicity, which can lead to serious health risks underwater, including convulsions and loss of consciousness.

Before immersing into a dive, ensuring that the Nitrox you've prepared matches your planned dive profile helps divers to stay within safe operating limits and extends bottom times while reducing the risk of nitrogen narcosis. Proper analysis guarantees the gas used aligns with the dive plan, allowing divers to dive confidently and safely within their training and experience.
