What does the term "decompression stop" refer to?

The term "decompression stop" specifically refers to a pause during ascent that allows nitrogen, which has been absorbed by the body during the dive, to safely exit the body. When divers are exposed to increased pressure underwater, their bodies absorb more nitrogen than they do at surface pressure. As they ascend and the pressure decreases, nitrogen can form bubbles if the ascent is too rapid. The decompression stop allows for a gradual release of nitrogen to help prevent decompression sickness, also known as "the bends." This concept is crucial in dive planning and safety, ensuring that divers ascend at a controlled rate and include necessary stops based on their depth and time underwater to minimize the risk of injury.
