Study on the Optimal Method for Photoplethysmograph Measurement at radial Artery
An electronic circuit for detecting photoplethy-smograph(PGp) at radial artery is developed, and experimentstudy on the optimal method for PGp measurement at theradial artery using local pressurizing cuff is carried out. Also,amplitudes of the arterial volume pulsation detected under the same cuff pressure are used as the evaluation standard, theoptimal measurement position, the combination of photoelectricsensor and the method for PGp measurement are discussed andexperimented. Experimental results show that the bigger Pgpcan be detected under the condition that the photoelectricsensor is located at 20mm position in wrist, the distancebetween centerlines of light-emitting diode (LED) andphotodiode (PD) is set to 7mm, the photoelectric sensor is set in the vertical placement, and LED is just located on the radialartery. From the study, the optimal method for Pgpmeasurement at the radial artery is determined.
