Background. The paper considers the methods of building an information and control complex that affects the human respiratory system. Such systems are used worldwide for the rehabilitation, treatment and prevention of patients with chronic obstructive pulmonary disease and heart failure. A two-circuit control method based on a decisionmaking system built using fuzzy logic allows for adaptive load on the respiratory muscles based on the information received in real time. Materials and methods. The methods of system analysis, fuzzy logic, and approximation theory are used in the work. Results. In the course of the conducted research, a block diagram of the information management complex was obtained, which includes a block for determining the level of human fitness and a decision support system. A method for testing the state of the human respiratory system and an algorithm for assessing the level of approximation of the respiratory system to the «norm» and «pathology» groups have been implemented. Conclusions. The proposed methods and tools make it possible to provide a configurable level of stress on the respiratory system of each patient, taking into account changes over time.
