Claim Text:
1. A method of estimating a central systolic blood pressure (cSBP) comprising: obtaining a peripheral blood pressure waveform of a pulse of a human subject within at least one cardiac cycle of the human subject, wherein the peripheral blood pressure waveform of the human subject's pulse is determined on a brachial artery of the human subject using a blood pressure cuff, and wherein the peripheral blood pressure waveform is obtained when pressure in the blood pressure cuff is adjusted to a defined pressure; applying a transfer function to the peripheral blood pressure waveform and calibrating the peripheral blood pressure waveform using defined peripheral blood pressure measurements, wherein the defined peripheral blood pressure measurements comprise at least two of pSBP, pDBP and pMAP, to provide an estimate of the central blood pressure waveform of the human subject's pulse; and electronically estimating the cSBP of the human subject using the estimate of the central blood pressure waveform.
