What should divers do to manage residual nitrogen effectively?

Following guidelines for ascent rates and surface intervals is vital for managing residual nitrogen effectively because it helps prevent decompression sickness, commonly known as "the bends." During the dive, nitrogen is absorbed into the body's tissues under increased pressure, and as a diver ascends, this nitrogen needs to be eliminated safely. Adhering to recommended ascent rates allows for a controlled reduction in pressure, enabling nitrogen to be released gradually and reducing the risk of bubble formation in the tissues and bloodstream.

Surface intervals are equally important as they provide the necessary time for the body to off-gas the residual nitrogen before the next dive. Proper management of surface intervals allows divers to engage in repetitive diving without excessively increasing their risk of decompression-related injuries. By following established guidelines, divers can ensure a safer diving experience and better gas management.
