空中晕厥是指飞行人员在飞行中尤其是在受头—盆向加速度作用下突然发生短暂的意识丧失。这种现象严重者可导致一等飞行事故。为防止或减少此类现象发生,研究空中晕厥问题是航空医学中的重要课题之一。本文试图阐明在模拟头—盆向加速度的条件下观察空中晕厥飞行人员的脑血流变化特点。实验方法观察对象:31名男性飞行员,分两组。第一组20人,年龄在20～37岁之间,平均26.4岁,该组飞行员均在近期(三个月内)发生过空中晕厥,简称晕厥组;第二组
Syncope refers to the flight crew in flight, especially by the head - basin acceleration under the sudden short-term loss of consciousness. This phenomenon can lead to serious first-class flight accident. To prevent or reduce the occurrence of such phenomena, the study of air syncope is one of the most important topics in aeromedicine. This paper attempts to elucidate the characteristics of cerebral blood flow changes observed in airborne syncope pilots under simulated head-to-basin accelerations. Experimental methods Observation object: 31 male pilots, divided into two groups. The first group of 20 people, aged 20 to 37 years old, an average of 26.4 years of age, the pilots in the group in the near future (within three months) had a syncope, referred to as syncope group; the second group
