METHOD OF DERIVING CENTRAL AORTIC SYSTOLIC PRESSURE VALUES AND METHOD FOR ANALYSING AN ARTERIAL DATASET TO DERIVE THE SAME

摘要

A METHOD (10, 100), SYSTEM AND COMPUTER READABLE MEDIUM FOR DERIVING CENTRAL AORTIC SYSTOLIC PRESSURE BY REVERSING THE ORDER OF A SET OF PREDETERMINED NUMBER OF BLOOD PRESSURE MEASUREMENTS TO OBTAIN A REVERSED BLOOD PRESSURE SET (14, 110); AVERAGING THE REVERSED BLOOD PRESSURE SET SUCH THAT THE AVERAGE SET REPRESENTS A MOVING AVERAGE WAVEFORM (22, 122); OVERLAYING THE REVERSED BLOOD PRESSURE SET AND THE MOVING AVERAGE WAVEFORM; IDENTIFYING A POINT OF INTERSECTION ON THE REVERSED ARTERIAL WAVEFORM AND THE MOVING AVERAGE WAVEFORM (24, 124), AND SETTING THE CENTRAL AORTIC SYSTOLIC PRESSURE AS A REVERSED BLOOD PRESSURE VALUE IN THE REVERSED BLOOD PRESSURE SET NEAREST TO THE POINT OF INTERSECTION (26, 126).
