Non-Invasive, Continuous, Accurate and Cuff-Less Measurement of Blood Pressure and Other Cardiovascular Variables by Pulse Wave Acquisition and Analysis Using Non-Invasive Sensors

摘要

A method for noninvasively measuring hemodynamic variables of a person includes physically configuring a sensor to measure the pulse of a person. The sensor generates a pulse waveform indicative of the pulse of the person. A processor obtains the pulse waveform from the sensor and the processor determines a reflection coefficient and reflection delay between an incident and a reflected wave, from which the processor determines the hemodynamic variables of the person from the reflection coefficient and the reflection delay.
