The state of intracerebral hemocirculation in the pilots during expert examinations to determine the tolerance for special exercise tests was studied. The cerebral circulation reactions were evaluated with the use of ultrasonic transcranial Doppler vasography. It is found that exercise tests depending on an intensity of exposure and directionality result in different degree of changes in the cerebral circulation parameters. In an effect of the flight-surgeon's appraisal the use of transcranial Doppler vasography during LBNP test to identify the persons susceptible to the syncopal states is advisable.
在确定特殊运动试验耐受性的专家检查期间，对飞行员的脑内血液循环状态进行了研究。使用超声经颅多普勒血管造影术评估脑循环反应。结果发现，取决于暴露强度和方向性的运动试验会导致脑循环参数出现不同程度的变化。在飞行医生评估的作用下，建议在下肢负压试验期间使用经颅多普勒血管造影术来识别易发生晕厥状态的人员。
