Abstract:
Based on Moens-Korteweg model & hydrostatic principle, a simple calibration method by changing vertical distance between heart and radial artery is proposed in this paper. Using hydrostatic pressure to change arterial pressure and pulse wave transmit time, consequently obtain several sets of cardiovascular parameters and finally build up relationship between blood pressure and pulse wave transmit time. Clinical tests have been carried with different age and gender for long and short time monitoring. The comparison results with Sphygmomanometer OMRON EW3152 show its promising accuracy and coincidence feature in blood pressure measurement.
