diving decompression theory

Diving decompression theory explains how divers safely ascend to the surface after deep or long dives. When underwater, divers breathe compressed air, causing nitrogen to dissolving into their tissues. As they ascend, pressure decreases, and excess nitrogen must be released gradually to avoid bubbles forming in their bodies, which can cause decompression sickness ('the bends'). Diver tables and computers calculate safe ascent rates and decompression stops, allowing nitrogen to be eliminated slowly. This process ensures a safe transition from high-pressure environments to the surface, preventing dangerous bubble formation in tissues and blood.
