Comparative Analysis of Methods of Laser Doppler Flowmetry and Doppler Ultrasound Measurement of Blood Flow during the Procedure of Intermittent Pneumatic Compression

Abstract

The results of the analysis of microcirculation of the blood flow of the toe and ultrasound Doppler measurement of blood flow in the femoral artery during the intermittent pneumatic compression procedure are presented. A professional device “Doctor Life Mark 400” (South Korea) was used for the pressotherapy procedure. Microcirculation was measured using a portable laser Doppler flowmeter “LAZMA PF” (Russia). Ultrasonic Dopplerograms were obtained using the device “Edan U50” (China) with a linear sensor model L15-7b with a frequency in pulsed Doppler mode (PW) 7.2 MHz. The study involved a group of 11 subjects without identified vascular disorders, the age of the group was from 23 to 42 years. The method of calculating the average speed and volume of blood flow over the period of the cardiac cycle was used for ultrasound Dopplerograms. Arterial resistance was evaluated, which was compared with the dynamics of perfusion in the limb. In the studies, approximately half of the test subjects had an increase in perfusion of the microcirculatory bed and a decrease in resistance of arterial vessels. At the same time, with an increase in the perfusion of the microcirculatory bed, a decrease in the resistance of arterial vessels was observed.
