""However, different people demonstrated different responses to body position change, which means that this new method of pulse wave velocity detection provides valuable information on the regulation of the peripheral blood flow," he added.According to the scientists, the significance of the research is that it helps to understand the interaction between light and the circulatory system and how scientists can benefit from this interaction. We decided to check if other people had the same effect, and the answer was yes.Scientists can examine blood vessels located in the carotid system in order to investigate the cerebral blood flow response (Photo: Pixabay)Washington: For the first time, alterations in capillary blood flowaround the face caused by body position change have been detected by researchers through the use of imaging photoplethysmography.

Therefore, this method will make it easier for scientists to investigate the physiological regulation of the peripheral blood flow in response to external stimuli, for example, gravity.It is not only hydrostatic pressure difference that affects the velocity, but also the response of the body to its position change.end-ofTags: blood flow, body position, healthRelated StoriesSmartphone app might soon offer new way to measure blood flowScientists cure skin melanoma of mice in trial, train body to stop tumours returning.Researchers design blood test to reveal a person's internal body clock.The full findings are present in the journal- Scientific Reports.The significance of the research is that it helps to understand the interaction between light and the circulatory system.

Professor Alexei Kamshilin said, "It all started when we examined migraine patients.Using imaging photoplethysmography, researchers from the ITMO University, in collaboration with colleagues from the Almazov National Medical Research Centre, managed to find out that pulse wave velocity (PWV) in the carotid area changes in response to body position change. This optical method allows researchers to detect both the velocity of the pulse wave moving from flowmeters Suppliers the heart to tissues and amplitude of blood pulsations in different areas of the body. When observing one of our volunteers, we suddenly noticed that the way he moved affected the results of the observations.Using this method, scientists can examine blood vessels located in the carotid system in order to investigate the cerebral blood flow response to various stimuli in health and disease.The technique of imaging photoplethysmography is among the most popular ones.
