Method of estimating pulse wave velocity

摘要

A method of estimating blood pressure Pulse Wave Velocity (PWV) in the aorta from a recording of a pressure waveform at a single site. The method comprises the following steps: 1. measuring the patient's arterial pressure relative to time in order to estimate a central pressure waveform (CPW); 2. estimating the patient's aortic pressure pulse transit time (PPTT) from the CPW; 3. estimating the patient's carotid to femoral arterial distance from the patient's physical characteristics; and 4. dividing the patient's estimated carotid to femoral arterial distance by the patient's estimated PPTT to estimate the patient's PWV.
