[The nature of the changes in the indices of intracerebral blood circulation in flight personnel performing functional tests].
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.
