Dive into the Depths of Success with the 2025 Enriched Air Nitrox Challenge – Breathe Easy and Conquer!

Question: 1 / 400

What is the role of a dive computer or dive tables when using EANx?

To measure underwater temperature

To calculate bottom times and safe dive profiles based on the gas mixture

The function of dive computers and dive tables in the context of using Enriched Air Nitrox (EANx) centers around calculating bottom times and determining safe dive profiles based on the specific gas mixture being used. When divers utilize EANx, they are dealing with different gas mixtures, notably those that have higher levels of oxygen than standard air. This variation in gas composition influences not only the allowable bottom time but also the decompression limits for the dive.

Using dive tables or dive computers, divers can accurately assess how long they can safely spend at a given depth without exceeding safe limits for oxygen exposure and nitrogen absorption. The increased concentration of oxygen found in EANx affects key aspects of diving physics, necessitating precise calculations to prevent issues such as oxygen toxicity. Therefore, it is essential for divers to utilize these tools to maximize safety and minimize the risk associated with diving at varying depths while using enriched air mixtures.
