What is the role of the dive computer when diving with EANx?

The role of the dive computer when diving with enriched air nitrox (EANx) is crucial for both safety and efficiency. The dive computer is designed to monitor the diver’s exposure to both nitrogen and oxygen, which is especially important when using gases with higher oxygen content than air. It provides real-time calculations of the diver's ascent rates and decompression limits based on the specific mix of gases being used.

When diving with EANx, oxygen exposure becomes a significant factor because higher concentrations can lead to oxygen toxicity if limits are exceeded. The dive computer takes into account the depth, time underwater, and the specific EANx mixture being used, to help ensure that divers stay within safe exposure limits. By calculating these factors, it aids divers in planning their dives more effectively and safely managing their ascent and any necessary decompression stops. This function is essential for reducing the risk of decompression sickness and oxygen toxicity, making it a vital tool while divers are using enriched air.
