ABSTRACT:
A method for estimating systolic and diastolic pressure is disclosed herein. The method includes obtaining a predetermined type of blood pressure data from a patient, and providing previously acquired blood pressure data obtained from a plurality of different subjects. The method also includes implementing the previously acquired blood pressure data to select systolic and diastolic amplitude ratios that most closely correlate with the predetermined type of blood pressure data obtained from the patient. The selected systolic and diastolic amplitude ratios are adapted to compensate for the effects of arterial compliance. The method also includes implementing the selected systolic and diastolic amplitude ratios to generate a systolic and diastolic blood pressure estimates.
