The object of the study is the process of monitoring and management of glycemic profile of a patient with type 1 diabetes. The purpose of the study is to increase the information content of the process of monitoring and management of glycemic profile in patients with type I diabetes by developing a method, model and hardware and software complex. Research Methods: mathematical modeling methods for constructing mathematical models; simulation method for developing glycemic profile management algorithm; methods of biotechnical systems theory for the development of structural and functional organization of the agroindustrial complex, theoretical and experimental methods for the development of a block of psychological support and experimental studies - for the introduction and testing of models, method and complex. Theoretical results: for the first time the method of determining the psychological personalized state of the patient as a mandatory component of the medical-diagnostic process of patients with type I diabetes, represented by the structural-functional interaction of the psychologist with the personal motivational-semantic sphere of the patient, is determined regulation of the somatic state of the patient by evaluating his personalized response to the disease and the criterion of objective determination of the current psych gy of the patient; first proposed a combined method of monitoring and determining the level of glucose in human blood, represented by a set of methods for determining the level of glucose in the patient's exhaled air, the method of evaluating emotional stress by the parameters of the photoplethysmogram and the method of similarity of the form of the photoplethysmogram to the same patterns, which preserves cover and presented by an interactive process of evaluation of the physiological parameters of the glycemic profile, which provides continuous monitoring and management of the patient's glycemic profile; the mathematical model of the process of monitoring and management of the glycemic profile of a patient with type I diabetes has been improved in the part of minimizing the time delay of receiving a signal on changes of insulin dose from 5 - 15 minutes to 3 - 4 minutes by continuous control of glucose biosensor parameters in monitoring and correction level blood after ingestion, exercise, or during illness, which allowed the small but frequent doses of insulin to be determined and administered by insulin pump and provided an effective a rhyme of glucose concentration in the patient's blood in the range of "normal" for a long time; improved by applying a mathematical model for monitoring and managing the glycemic profile, the process of estimating differences between parameters, λ (determines the amount of glucose utilized in 1 unit of insulin) and µ (reflects the glucose output through the kidneys when the critical level is exceeded), which revealed no differences confirmed the informative content of only one significant parameter α (glucose sensitivity), which corresponds to the glucose level and determines the rate of production of insulin within the established range of the norm, that n confirms the diagnosis of type I diabetes. The practical results are the development of a hardware and software system for monitoring and management of the glycemic profile, which provides continuous monitoring of glucose level, forms personalized control effects on the principle of biological feedback, takes into account the quantitative regularities of physiological processes and performs non-pulmonary disease . Degree of implementation - the results of the dissertation were implemented in the practical activity of the National Center for Primary Health Care of the Kompaniyiv District Council, in the Vinnitsa Regional Clinical Specialized Endocrinology Center, in the educational process of the Department of Biomedical Engineering in Vinnitsa National Technical University while teaching the relevant disciplines. Sphere (field) of use - medicine.
