Abstract
The article is devoted to the problem of studying microcirculation, because one of the reasons for the development of microcirculation disorders is hypoxia, which is associated with a violation of the normal anatomy of the capillary wall, changes in the properties of blood rheologies, acceleration or deceleration of microflow. Capillaries are the first to react to long-term disturbance of nasal breathing by changing the functional state and morphological restructuring of micro vessels in the bloodstream. Based on the results of the research work, software was developed that was tested on patients with pathology of intranasal structures and impaired respiratory function. The advanced method of optical capillaroscopy allows not only to perform a visual assessment of the condition of microvessels, but also to determine such an important parameter as blood flow velocity and actually replace the laser Doppler study.
