Non-Invasive, Non-Occlusive Blood Pressure Estimation using Ultrasound: Clinical Results

Abstract

State-of-the-art blood pressure measurement devices suffer from various pitfalls; they are either occlusive, invasive, inaccurate, hard-to-use, or operator dependent. In order to address many of these shortcomings, in this paper, force-measured ultrasound is used at a patient's carotid artery. Subsequently, an optimization utilizing finite elements estimates systolic and diastolic blood pressure. Clinical tests on healthy volunteers show that the algorithm accurately estimates both systolic and diastolic blood pressures.
