Abstract
A method for non-invasive hemodynamic monitoring of patients. The method comprises using ultrasound to obtain a continuous blood velocity signal and continuous arterial diameter signal. The method further comprises extracting waveform features from these two signals which can be used to estimate hemodynamic parameters. A transfer function is used to convert values of a pre-defined set of waveform features into values of one or more hemodynamic parameters. To enhance accuracy, ultrasound data is acquired over a time window and an ensemble average blood velocity waveform is computed from a series of waveforms detectable in the blood velocity-time signal over said time window.
