Abstract: A method and arrangement for the indirect measurement of systolic and diastolic blood pressure is disclosed which involves applying an occluding inflatable cuff to a body member, with the pressure applied thereby being cycled between a pressure greater than systolic and a pressure less than diastolic. Systolic blood pressure is detected by sensing the point in the pressure cycle at which the blood flow in the occluded member shifts between a flow and no flow condition, while diastolic blood pressure is detected by sensing a characteristic change in slope of blood pulse wave form changes occurring with changing cuff pressures which occurs at a cuff pressure equal to the diastolic pressure. An approach for correcting the systolic and diastolic pressure measurements obtained by this method at one point of the body to give equivalent readings of the systolic and diastolic blood pressure at another point is also disclosed.
