Photoreoplethysmography as a method for studying the regional blood supply to skin wounds
In an experiment on pigs, the photoreoplethysmography method adapted for this purpose was used to characterize the blood supply to the granulation tissue of the bottom of skin wounds under various therapeutic effects. It has been shown that the method allows one to graphically record the state of volumetric blood flow in tissues, to carry out a comparative assessment of microcirculation in tissues due to the possibility of simultaneous registration in several places. The resulting photoreoplethysmograms make it possible to quantify the amplitude and time parameters of blood flow.
