A team at ITMO University in Saint Petersburg, Russia, has found photoplethysmography can noninvasively capture unique information on the regulation of a patient’s peripheral blood flow, according to research in Scientific Reports.
Alexei Kamshilin led the study that imaged 73 healthy patients using photoplethysmography. The noninvasive technique, which measures a patient’s pulse wave velocity as blood moves away from the heart, linked changes in the carotid system to changes in physical movement.
“Demonstrated feasibility of pulse wave velocity measurements in the pool of carotid arteries provides considerable advantages over other technologies,” Kamshilin and his co-authors wrote. “Moreover, possibilities of the method to estimate physiological regulation of the peripheral blood flow have been demonstrated. The proposed concept allows development of noninvasive medical equipment capable of solving a wide range of scientific and practical problems related to vascular physiology.”
