Application of the human organism adaptation model to extreme environmental conditions for scientific support of the health protection system of military servants

Abstract

The NATO Medical Doctrine emphasizes the need to use scientific support to create a modern system of medical support for the health of military personnel. When considering various aspects of joint operations, it is emphasized that extreme environmental conditions are taken into account, as well the features of the complex technical conditions of life of the military contingent. The issue of professional selection is also important. To solve these problems, it is proposed to use mathematical modeling, in particular mathematical models of transport and mass exchange of respiratory gases, self-organization of the respiratory system and blood circulation, and urgent adaptation of the human body to extreme environmental conditions. A mathematical model of the functional breathing system of continuous interaction system operators is provided, which can include pilots and drivers of land, water and underwater transport. To study the influence of environmental temperature factors, the given model is proposed to be used in interaction with the thermoregulation model. In these models, the breathing process is considered as a controlled dynamic system, in which the executive organs of self-regulation direct their efforts to maintaining a state of equilibrium with oxygen and carbon dioxide tensions at a given level of disturbing influences on the body. Analysis of these models allows establishing the main regularities of the course of the breathing process, the role of regulatory mechanisms in providing and maintaining the main function of the respiratory system under the most diverse conditions of human life, to establish the most important properties of the studied process. Mathematical models of adaptation make it possible to predict the stationary state of the organism at a given level of disturbing influences and thus manage the process of training and preparation of military personnel and contingent selection for carrying out certain operations.
