1 临床资料 石某,男,26岁。某部歼-7飞机飞行员。飞行时间800h,于1997年7月来我院疗养。经常规体检未发现异常,开始参加航空生理训练,训练项目是常规加压供氧。我们应用空军航空医学研究所研制的YD型地面供氧器,训练前查心电图正常,心率80次/min,一般情况良好。在模拟12000m高空飞行训练时,加压供氧由3.9kPa～5.9kPa(40cmH_2O～60cmH_2O)时,飞行员突然出现胸闷、憋气、窒息感、面色苍白及全身出冷 1 clinical data Shimou, male, 26 years old. Some F-7 pilot. Flight time 800h, in July 1997 to our hospital convalescence. Routine physical examination found no abnormalities, began to participate in aerobics training, training program is conventional pressurized oxygen. We use the Air Force Institute of Aeronautics and Astronautics developed YD-type ground oxygen supply, check ECG before training check normal, heart rate 80 beats / min, generally good. During simulated flight training at altitude of 12000m, pilots suddenly developed chest tightness, suffocation, asphyxia, paleness and whole body cooling when pressurized with oxygen from 3.9kPa to 5.9kPa (40cmH2O to 60cmH2O)
