What should divers be aware of when using nitrox?

When diving with nitrox, divers must be particularly aware of the impact of oxygen toxicity. Nitrox, which is a mixture of nitrogen and oxygen, increases the proportion of oxygen in the breathing gas. While this can lead to benefits such as reduced nitrogen absorption and extended bottom times, it also presents a risk of oxygen toxicity at deeper depths or extended exposure times. Oxygen toxicity can manifest as symptoms ranging from visual changes and nausea to more severe neurological effects that can impair a diver's ability to function underwater.

Understanding the depth limits for specific nitrox mixes and adhering to the maximum operating depth is crucial to ensure safety. Proper training equips divers with strategies for monitoring their exposure to oxygen, allowing for safe diving practices while utilizing nitrox. This makes awareness of oxygen toxicity essential for safe and effective diving with enriched air mixtures.
