空中晕厥是飞行人员在飞行中突然丧失工作能力和造成飞行事故的重要原因。它的医学鉴定问题受到了航医界的重视,尽管在临床上有较多的检查方法,但在应用中仍不理想。人体离心机虽可模拟正加速度造成的空中晕厥,但由于设备庞大,难于推广。因此,探索一种既可模拟晕厥时人体的生理变化又能在一定范围内推广使用的无创性方法 Aerial syncope is a significant cause of sudden incapacity and flight accidents of pilots in flight. Its medical appraisal has received great attention from aeromedicine community. Although there are more clinical tests, it is still not ideal in the application. Although the body centrifuge can simulate the positive acceleration of the air syncope, but due to the huge equipment, it is difficult to promote. Therefore, to explore a non-invasive method to simulate the physiological changes of the human body during syncope and to promote the use within a certain range
