From: Estimation of central systolic blood pressure using an oscillometric blood pressure monitor
Parameters identified from the brachial pulse (a) and the pulse volume plethysmography (PVP) (b) waveforms for the prediction of aortic systolic blood pressure. Ad, the area under curve during diastole; As, the area under curve during systole; DBP, pressure value at end-diastole; ESP, end-systolic pressure, pressure value at onset of diastole; SBP, systolic blood pressure; SBP2, pressure value of the late systolic shoulder produced by wave reflections.
