OPTICAL-ELECTRONIC TECHNOLOGIES OF EVALUATION OF CHANGE OF PERIPHERAL CIRCULATION AT PHOTON INFLUENCE FOR COMPLEX TREATMENT OF CHRONIC DIAGNOSIS

Abstract

The paper deals with the prospect of using the photoplethysmographic method for the evaluation of microcirculatory changes in peripheral circulation to study the processes that occur during photonic physiotherapy exposure for the complex treatment of chronic complications of diabetes. It is shown that photonic radiation helps to increase the elasticity of the walls of blood vessels, the elasticity of erythrocytes, oxygen transport function of the blood, the activity of cell membranes, the acceleration of processes of tissue regeneration, the reduction of lipid oxidation, the normalization of rheologic indices. After procedures of phototherapy in patients, the syndrome of "thermoamputation" disappeared, swelling of the legs decreased, as well as significantly decreased pain in the legs, numbness took place, leg cramps stopped. It is shown that photonic radiation of the Barva apparatus leads to anti-inflammatory, desensitizing, analgesic, antispasmodic, and anti-edema actions, which was confirmed in this study in the treatment of patients with complications of diabetes. To control the level of peripheral circulation, a photoplethysmographic method was used, which, compared to other known methods of blood circulation research, has certain advantages, because it allows to conduct studies in both transient and reflected light. It allows to obtain useful information about vascular activity, vascular response to specific substances, as well as to study blood circulation in isolated vessels of different caliber (veins, arteries, etc.). In addition, the photosensor does not cause compression of vessels of biological tissue, that is, does not cause impaired blood circulation. Thus, it is obvious that the most promising direction of registration of physiological parameters is the use of non-invasive methods of diagnosis, among which the wide development has received optical methods of registration and transformation of biomedical information and allows to study microcirculation in human tissues without impaired circulation in the study area, which is essential for medical practice.
