摘要:
The present invention refers to a method of approximating a patients 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 pulsen_measured(t) of a patient, thereby applying a clamp pressure clampn(t), (b) weighting the measured pulse signals pulsen_measured(t) using a weighting function to obtain weighted pulse signals pulsen_weighted(t), and (c) adding up the weighted pulse signals pu/sen_weighted(t) to obtain an approximation of the patients pulse wave pulseapprox(t). The invention also refers to a logic unit and a system for approximating a patients pulse wave based on non-invasive blood pressure measurement.
