Method for approximating a pulse wave of a patient based on non-invasive blood pressure measurement, a logic operation device and system

摘要

The present invention refers to a method of approximating a patient's pulse wave based on non-invasive blood pressure measurement, comprising the following steps: (a) non-invasively measuring a sequence n=1 ... N of pulse signals pulse n _ measured (t) of a patient, thereby applying a clamp pressure clamp n (t), (b) weighting the measured pulse signals pulse n _ measured (t) using a weighting function to obtain weighted pulse signals pulse n _ weighted (t), and (c) adding up the weighted pulse signals pu / se n_weighted (t) to obtain an approximation of the patient's pulse wave pulse approx (t). The invention also refers to a logic unit and a system for approximating a patient's pulse wave based on non-invasive blood pressure measurement.
