Abstract
Diagnosis of blood circulation in the microvessels of the skin allows you to predict the presence of microcirculatory disorders in the body, assess their severity and monitor therapy. Currently, one of the promising methods for assessing blood microcirculation in the vascular bed is laser Doppler flowmetry. Due to its high sensitivity to the psycho-functional state of the body, its use is most effective when conducting functional tests. One of the most accessible is a functional test with a change in the position of the hand. The use of a functional test associated with a change in the position of the entire human body or its parts, for example, limbs, is a method for diagnosing various diseases of the cardiovascular system and disorders of the autonomic nervous system. However, in the case of a venoarteriolar reflex, an erroneous interpretation of Dopplerograms and their wavelet spectra may be obtained. We conducted a study of the effect of the venoarteriolar reflex during a test with a change in the position of the limb according to a set of parameters characterizing the dynamics of blood circulation in the microvessels of the finger using laser Doppler flowmetry.
