In deep-sea diving, what does the term "decompression" refer to?

In deep-sea diving, "decompression" refers to the gradual ascent to the surface to prevent decompression sickness, often known as "the bends." When divers are exposed to elevated pressures underwater, their bodies absorb more nitrogen from the air they breathe. If a diver ascends too quickly, this nitrogen can form bubbles in the bloodstream and tissues, leading to serious health risks. Therefore, decompression involves staged stops during ascent, allowing nitrogen to be safely eliminated from the body through respiration.

This process is crucial for maintaining diver safety and ensuring that they can return to the surface without experiencing adverse effects from rapid changes in pressure. Proper decompression procedures vary based on the depth and duration of the dive, emphasizing the need for meticulous planning and execution.
