What does the term "decompression sickness" refer to?

Decompression sickness, often referred to as "the bends," is primarily associated with the formation of nitrogen bubbles in the body tissues and bloodstream when a diver ascends too rapidly after a dive. During a dive, the body absorbs nitrogen from the breathing gas due to the increased pressure underwater. If a diver ascends too quickly, the rapid decrease in pressure can cause the nitrogen to come out of solution and form bubbles, which can lead to various symptoms including joint pain, dizziness, and in severe cases, can affect the nervous system or lead to unconsciousness. Understanding this phenomenon is crucial for divers, as it highlights the importance of proper ascent rates and adherence to dive tables or computers to prevent such conditions.

Other options are not accurate representations of what decompression sickness entails. The condition is not associated with stings, fatigue, or simply categorized as a generalized deep-sea injury, making the understanding of nitrogen bubbles and pressure changes essential in preventing this serious condition.
