Physiological response of pilots to the LBNP-, flight-, and centrifuge load.
The possibility of the LBNP method's utilization at persons with low resistance of the cardiovascular system to the orthostatic load is a matter one of the research projects of IAM. We concentrated in previous stages our effort on an evaluation of basic physiological responses of the organism to this type of a load and on determination of reliable markers of the precollapse state. After analysis of results of examinations of 64 probands' set we defined qualifying criteria to the prediction for selection of individuals with the insufficient orthostatic resistance. Verification of experimental results by the comparison with well-established examination methods, during a real flight load and at the examination in a human centrifuge, is a goal of the following research activity. In current period of the task's solution the physiological response to an LBNP load has been compared with the physiological response to the load during real flight in an aircraft.
