Type 1 decompression sickness features include

• A. Central nervous system disorders
• B. Skin manifestations and bends
• C. Chokes
• D. High fever

Answer: (B)

Type I decompression sickness is the milder form, caused by nitrogen coming out of solution after a rapid ascent and forming bubbles in tissues. The hallmark features are musculoskeletal pain—often described as the bends in joints and muscles—and skin changes, such as itching or a mottled, marbled appearance of the skin (cutis marmorata). These signs reflect bubbles affecting the skin and joints rather than the nervous system or lungs. By contrast, symptoms involving the central nervous system, such as confusion, numbness, or weakness, and pulmonary signs like chest discomfort or coughing (the chokes), point to Type II DCS, which involves more serious, deeper compartments. Fever isn’t a defining feature of decompression sickness.
