Abstract

A Grumman EA-6B aircraft experienced a rapid pressurization failure at 27,000 feet. All four crew members had removed their oxygen masks and were breathing cabin air pressurized to 8,000 feet before the incident. Although none of the crew members developed signs or symptoms of decompression sickness, the potential for adversity was realized by all. Altitude decompression sickness (DCS) and pulmonary overinflation syndrome (POIS) represent potentially fatal complications of rapid decompression or uncontrolled ascent in aircraft. The signs and symptoms of DCS range from mild joint pain to eventual cardiopulmonary collapse and death. The symptoms of POIS are usually more abrupt and lethal. The medical management of DCS and POIS includes (1) maintenance of airway and cardiopulmonary resuscitation if necessary: (2) administration of 100% oxygen; (3) descent as per Naval Aviation Training and Operating Procedures Standardization guidelines; (4) horizontal body position; (5) maintenance of fluid intake; and (6) early medical evaluation by a flight surgeon or other physician qualified in the management of DCS. Symptoms of DCS may appear up to 24 hours after decompression, and continued monitoring or grounding of exposed individuals during this time is essential. Many controllable factors may predispose to DCS/POIS, and preventive measures should be taken to ensure maximum reduction of risk.
