METHODS FOR MEASURING BLOOD PRESSURE
First Claim
1. A method of estimating a central systolic blood pressure (cSBP) of a subject, the method comprising the steps of:
- determining a peripheral blood pressure waveform of the subject'"'"'s pulse and at least two peripheral blood pressure measurements within the cardiac cycle of the subject; and
manipulating the peripheral blood pressure waveform with a transfer function to provide an estimate of the central blood pressure waveform of the subject'"'"'s pulse,wherein the at least two peripheral blood pressure measurements within the cardiac cycle of the subject and the peripheral blood pressure waveform of the subject'"'"'s pulse are determined at substantially the same point on a peripheral artery of the subject, and wherein the estimate of the central blood pressure waveform of the subject'"'"'s pulse provides an estimate of the central systolic blood pressure of the subject.

Abstract
The application relates to an apparatus and a method for estimating a central systolic blood pressure (cSBP) of a subject, in which a peripheral blood pressure waveform of the subject'"'"'s pulse and at least two peripheral blood pressure measurements within the cardiac cycle of the subject are determined and the peripheral blood pressure waveform is manipulated with a transfer function to provide an estimate of the central blood pressure waveform of the subject'"'"'s pulse. The at least two peripheral blood pressure measurements within the cardiac cycle of the subject and the peripheral blood pressure waveform of the subject'"'"'s pulse are determined at substantially the same point on a peripheral artery of the subject. The estimate of the central blood pressure waveform of the subject'"'"'s pulse provides an estimate of the central systolic blood pressure of the subject.
