Abstract
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 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 pulsen weighted(t) to obtain an approximation of the patient's pulse wave pulseapprox(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.
