How does Nitrox affect ascent rates and safety stops?

• A. It allows for shorter safety stops
• B. It allows for longer safety stops due to reduced nitrogen absorption
• C. It requires no safety stops
• D. It increases ascent rates

Answer: (B)

Using Nitrox can affect ascent rates and safety stops due to its unique properties related to nitrogen absorption. When diving with Nitrox, which is oxygen-enriched air, divers experience reduced nitrogen partial pressures. This leads to decreased nitrogen absorption in the body during the dive. As a result, divers often find they can safely extend their safety stops without significantly increasing the risk of decompression sickness. The increased oxygen levels in the breathing gas can help mitigate the buildup of nitrogen, allowing divers to ascend more conservatively and safely. This reduced nitrogen loading in the tissues is a key factor in the way Nitrox divers approach their ascent and safety stop strategies, making the option relating to longer safety stops due to reduced nitrogen absorption the most accurate.
