Operation Everest II: Altitude decompression sickness during repeated altitude exposure.

摘要: The incidence of altitude decompression sickness (ADS) was studied in 23 scientists during repeated exposure to 15,000-29,000 ft (4572-8839 m) a chamber. Prior each exposure, 30-60-mm pre-breathing period with 100% oxygen took place. Ascent made an at rate 2000 X min-1. altitudes ranged from m). Symptoms reported appear consistent previous reports. Incidence ADS 26,000-29,000 (7925-8839 29.7%, 274 chamber flights and 1264.6 h time. appeared related frequency severity altitude, physical activity. not age, duration or body index (weight/height 2). This high this study is similar that by NASA.
