What should you consider when choosing a dive computer for Nitrox diving?

• A. It should allow for deep diving
• B. It must provide accurate ascent rate data
• C. It should track both Oxygen and Nitrogen exposure
• D. It must have an air mode for comparison

Answer: (C)

When choosing a dive computer for Nitrox diving, it is crucial to select a device that tracks both Oxygen and Nitrogen exposure. This capability is vital because Nitrox, which is a mixture of nitrogen and oxygen, alters the way divers need to manage both gases compared to standard air dives. Tracking Oxygen exposure is particularly important due to the increased risk of Oxygen toxicity at higher partial pressures, especially when using mixes with elevated Oxygen levels, typically above 21%. A dive computer that monitors both gases helps divers stay within safe limits, ensuring they adhere to the maximum permissible exposure times for both Oxygen and Nitrogen. This includes calculating no-decompression limits and ensuring safe ascent profiles, which directly correlates with minimizing the risks of decompression sickness. Thus, having accurate tracking of both gases allows the diver to make informed decisions, plan dives safely, and calculate necessary stops during ascents effectively.
