What role do dive computers play in planning EANx dives?

Dive computers play a crucial role in tracking nitrogen absorption during EANx (Enriched Air Nitrox) dives. Their primary function is to monitor a diver's exposure to nitrogen based on the depth and duration of the dive. As divers breathe a mix of gases, including higher percentages of oxygen, the dive computer calculates the nitrogen that is absorbed into the body tissues over time. This information is vital for ensuring that divers remain within safe limits to avoid decompression sickness.

By tracking nitrogen levels accurately, dive computers allow divers to adjust their dive plans in real-time, providing the necessary data to manage bottom times and additional safety considerations. This aspect of dive computers is especially important in EANx diving because different blends of nitrox can alter nitrogen absorption rates compared to air dives. Therefore, utilizing a dive computer enhances safety and awareness during EANx dives, helping divers maintain a thorough understanding of their physiological status underwater.
