What is a common misconception among divers regarding EANx?

The notion that all richer mixes inherently mean greater safety compared to air reflects a common misunderstanding among divers regarding Enriched Air Nitrox (EANx). While it is true that using oxygen-enriched mixes can extend no-decompression limits and reduce nitrogen uptake, this does not automatically translate to a universally safer diving experience.

In fact, breathing air with a higher oxygen percentage increases the risk of oxygen toxicity, particularly at greater depths. The risks associated with higher partial pressures of oxygen need to be managed carefully and divers must be trained to understand the maximum operating depth for any given mix. Therefore, simply using a richer mix does not guarantee enhanced safety; divers must still adhere to proper depth limits and dive tables. Understanding these principles is crucial for safe diving practices with EANx.
