Typical symptoms of decompression illness (DCI) may include:

Joint pains, skin rashes, and itching are typical symptoms of decompression illness (DCI), particularly in the context of decompression sickness, often referred to as "the bends." This condition occurs when a diver ascends too rapidly, causing nitrogen bubbles to form in the body tissues and bloodstream. The symptoms can vary widely, but musculoskeletal pain is one of the hallmark signs.

Joint pains, also known as "the bends," are particularly characteristic because they are often described by divers experiencing this condition. The itchy skin and rashes can arise from the body’s inflammatory response to the presence of these gas bubbles. This combination of symptoms is critical for recognizing DCI early, allowing for timely treatment such as hyperbaric oxygen therapy.

Other options describe symptoms that do not align as closely with DCI. For instance, tunneling of vision is not a common symptom associated with DCI; rather, it pertains to different phenomena associated with physiological stress or other visual disturbances. Cyanosis, while a significant indicator of hypoxia or lack of oxygen, does not directly relate to the symptoms typically seen during DCI. Profuse sweating is more indicative of stress or anxiety rather than a specific symptom of decompression illness.
