Software Filter Based Algorithm for Oscillometric Blood Pressure Measurement and Its Android Implementation
摘要
Abstract
To overcome the difficulties of conventional oscillometric blood pressure measurement in the extraction of pulse shock wave and the selection of waveform mutation point,an improved algorithm is presented that incorporates software filter into oscillometric method.In the software filter based algorithm,the pulse oscillation wave with distinguishable feature points is effectively extracted by a concatenated processing of software filter from the hybrid pressure signal samples,the mutation points are selected using the feature point method in a certain amplitude range determined by the amplitude characteristic ratios method,and the systolic and diastolic pressures are finally measured.The algorithm is simulated in Matlab,and implemented in intelligent mobile platform of Android.Simulation results in Matlab show that the algorithm can provide more reliable and accurate measurements of blood pressure.关键词
