OBTAINING THE PHYSIOLOGICAL DATA USING THE PHOTOPLETHYSMOGRAPHIC METHOD
AbstractThe activity of the cardiovascular system is very important for the overall health of a human being. The Photoplethysmographic method is an effective tool of assessing the activity of the heart. The method is based on recording changes in blood volume in the blood vessels of the individual. The report presents a non-invasive way to obtain physiological data using a created device based on the Photoplethysmographic method. The created device consists of a photodetector, infrared light-emitting diodes, and small pulse rate sensors. The proposed portable device has been tested with three types of interfaces. The received data from the Photoplethysmographic device is transmitted to a personal computer and stored for further processing.
