Abstract: In an approach to non-invasive blood pressure measurements, a blood pressure measurement system receives a pulse curve signal representing a sequence of pulse curves of a subject from a pressure cuff. The blood pressure measurement system applies a weighting function that applies one or more weights to a pulse curve of the sequence of pulse curves to obtain a weighted pulse curve and the one or more non-constant clamp pressure signals are a weighting function input parameter. The blood pressure measurement system sums at least the weighted pulse curve and a second weighted pulse curve, which approximates a shape and an amplitude of a pulse wave of the subject. The blood pressure measurement system determines a health status of the subject based on the pulse wave and generates a graphical representation of the pulse wave of the subject and the health status of the subject.
