Abstract

A blood pressure measurement device and associated operating method utilize a measurement algorithm based on a plurality of measurements, supplying a unique ability to increase diagnostic and analytical success in detection. In an illustrative implementation, three measurement techniques are used in combination to improve overall measurement accuracy. A first of the three techniques is an ascultatory technique. A sound measurement acquired from a microphone located in the measurement cuff detects start and end Korotkoff sounds using a combination of filters. A second technique is an oscillometric technique that is commonly found in many low-cost blood pressure measurement devices. A pressure cuff is used to measure pressure oscillations, which are detected and monitored using mean pressure, and systolic and diastolic pressure ratios to identify systolic and diastolic blood pressure. A third technique, called a pattern recognition to identify systolic and diastolic pressures. A signal from the pressure sensor is used in addition to the three techniques to quantify the regions of sound under analysis.
