A 43-year-old female recreational scuba diver presented to the emergency department 1 hour after a rapid, uncontrolled ascent. Her presentation included progressing confusion, slow and slurred speech, and complaints of headache and hypesthesia over her forearms and anterior thighs bilaterally. Differential diagnosis included arterial gas embolism and decompression sickness. She underwent recompression therapy with US Navy Table 6 within 120 minutes of her ascent. After recompression therapy, the patient had signs and symptoms consistent with severe rhabdomyolysis, including creatine kinase levels of 36,000 U/L and myoglobinuria.

Decompression injuries are potentially life-threatening incidents, generated by a rapid decline in ambient pressure. Although typically seen in divers, they may be observed in compressed air workers and others exposed to hyperbaric environments. Decompression illness (DCI) results from liberation of gas bubbles in the blood and tissues. DCI may be classified as decompression sickness (DCS) or arterial gas embolism (AGE), depending on where the gas bubbles lodge. DCS occurs after longer exposures to a hyperbaric environment with correspondingly larger up-take of inert gas. DCS may be classified into type 1 with cutaneous symptoms and musculoskeletal pain only or type 2 with neurologic and/or pulmonary symptoms as well. AGE usually results from a pulmonary barotrauma, and with cerebral arterial involvement, the symptoms are similar to a stroke. The most important therapy, in the field, is oxygen resuscitation with the highest possible concentration and volume delivered. The definitive treatment is rapid recompression with hyperbaric oxygen therapy. Additional therapeutic measures are discussed.
