One of the most important tasks for occupational medicine is ensuring the later development of fatigue and maintaining optimal stability of the functional state of a person — the operator of continuous interaction systems. A comprehensive study of the oxygen supply of the human body in the process of adaptation to new living conditions and new types of activity allows us to identify the leading links in the cascade of compensatory reactions and evaluate the functional reserves of the body. Difficulties of a methodological nature that arise when characterizing a person’s functional state in the process of his work lead to the need to build mathematical models that describe the functions of basic physiological systems of the body for theoretical study of the state of these systems during hard work, assessing the reserve of regulatory mechanisms, predicting possible consequences and correcting the state of organism. One of such models is a mathematical model of mass transfer and mass transfer of respiratory gases in the human body, which allows simulating disturbances in the internal and external environment in the dynamics of the respiratory cycle and, thus, predicting possible reactions of the body to these disturbances. The model investigated the compensatory reactions of the respiratory system while simulating intense operator activity. Obtained results indicate that the intensification of this activity, associated with an increase in the rate of oxygen consumption by brain tissues by 10-30%, does not cause a significant restructuring of the cardiorespiratory system, more intense activity leads to the active inclusion of the regulation mechanisms of the cardiovascular system and external respiration system, a change in the tone of smooth muscles and is associated with the development of hypoxia. The simulation on a mathematical model of a complex situational conditions for the organism of an average person showed that when compensating for the load in a complex situational conditions, when deciding, the decisive role belongs to the functional of the control performance by hypercapnic stimulus, and the behavior of the minimized functional is more influenced by a change in the ventilation parameters. Determining the optimum of the human operator and the corresponding changes in the most informative indicators makes it possible to predict the boundaries of the zone of optimal working capacity, and in the future, go on to control the functional state of the operator, improve the quality and reliability of the professional selection procedure and conduct a balanced personnel policy for operators of continuous interaction systems.
