Abstract:
1. A system for deriving central aortic systolic pressure comprising: an arterial waveform measuring device; and a processing unit; wherein the arterial waveform measuring device takes a set of blood pressure measurements at predetermined intervals until at least one arterial waveform is represented by the set of blood pressure measurements taken, the set of blood pressure measurements representative of one arterial waveform then being communicated to the processing unit which: a) determines an integer interval value; b) averaging a series of consecutive blood pressure measurement readings in the set equal to the integer interval value commencing from an f c) stores the averaged value in a central aortic systolic pressure set; and d) sets the central aortic systolic pressure as the highest value in the central aortic pressure set; wherein steps (b) and (c) are repeated with the value of f commencing at 1 and being incremented by 1 each time until the value of f plus the integer interval value equals the number of blood pressure measurements in the set.
