A testing, evaluating and control system for identifying and stabilizing physiological parameters

Abstract

This paper presents a testing, evaluating, and control system which tries to identify some physiological parameters and the possibilities to stabilize them. Two experiments are described. The first one describes the influence of mental activities on blood pressure and heart rate on the basis of measuring ECG and finger arterial pressure. The second one describes the possibility to differentiate psychological states of the tested person. The testing place should allow for the stabilization of psychological states on the basis of physiological parameters measurement by convenient selected physiological load.The task of our research was to evaluate the physiological reaction of tested persons and to try to stabilize their mental state or to control them by various physiological Ioad. From the pedagogical point of view it is possible to simulate the process and to search for an analogy among biological and technical subjects in biomedical engineering. This analogy can be a situation involving controlling the activity and work of a person. As an example, we can take the interface during communication between a student and a computer. k.We concentrated our effort on some basic experiments applying the available equipment to find and to predict the relation between psychological effects of stress and physiological parameters of the tested a person.It is necessary to search for two relationships:1. The relation between physiological parameters and the physiological state of a person, 2. The selection of physiological load to the physiological state of person.It is the task of an expert system to estimate the physiological state of a person from physiological data. The task of fuzzy-neural network or fuzzy automat is to select the psychological load according to the criteria to attain maximum information during the minimum time period with respect to physiological changes in a limited range.
