Method of Obtaining an Estimation of a Person's Aortic Blood Pressure
First Claim
1. A method of obtaining an estimation of a person'"'"'s aortic systolic blood pressure, which method comprises non-invasively measuring the person'"'"'s brachial systolic blood pressure, non-invasively measuring the person'"'"'s brachial diastolic blood pressure, obtaining the person'"'"'s radial augmentation index by measuring the person'"'"'s radial pulse waveform, and obtaining the estimation of the person'"'"'s aortic systolic blood pressure from the following equation:
-
aSBP=α
