Which DCS form is characterized by chest pain and a dry nonproductive cough?

• A. The Creeps
• B. The Chokes
• C. CNS Manifestations
• D. The Bends

Answer: (B)

Decompression sickness presents in different forms based on where bubbles travel after a rapid ascent. Chest pain with a dry, nonproductive cough points to the pulmonary form, often called “the chokes.” Here, nitrogen bubbles lodge in the lungs and pulmonary vessels, irritating lung tissue and impeding gas exchange, which produces chest pain and coughing without sputum. This pulmonary involvement distinguishes it from other DCS forms that affect the joints and muscles (The Bends), the nervous system (CNS Manifestations), or the skin (The Creeps). The chokes are the classic manifestation when the lungs are the primary problem, reflecting bubble-related irritation and possible mild pulmonary edema rather than neurological or musculoskeletal symptoms.
