Abstract
An improved method and apparatus for non-invasive determination of blood pressure is disclosed. The oscillometric technique is employed, wherein a valve representative of the blood pressure is derived from a signal representative of the pressure oscillations in a cuff, where the value is derived for a plurality of cuff pressures, and where the cuff pressure corresponding to the maximum of the values derived from the pressure oscillations is taken to be the mean arterial pressure. The instant method uses as the value the complementary oscillation index which is defined to be the area bounded by a line connecting successive peaks in the signal and the signal beneath the line, divided by the time between peaks. Apparatus employing both digital and analog circuitry is employed.
