Abstract

Monitoring of person microcirculatory bed state is one of the important problems of modern medical diagnostics. Due to the fact that many diseases cause changes of microcirculatory blood flow velocity, and timely diagnosis of these diseases prevents the development of pathologies. Currently, there are many methods for assessing of the capillary bed state. However, the most effective diagnostic methods for determining the main parameters of microcirculation include the method of dynamic light scattering. In this paper the speckle correlation sensor of microcirculatory blood flow velocity registration is considered. Using this setup, monitoring of blood flow velocity of a group of people under various conditions were studied. The results of these studies are presented. The measurement results showed that the installation is sensitive to external factors and allows you to record rapid changes in the speed of capillary blood flow. Also, the rate of blood flow in patients varies, depending on the state of their microvasculature, this fact will allow doctors to monitor the state of the human capillary system.
