Pulse Signal Monitoring and Analysis for Home Healthcare

Abstract

Health prognosis based on pulsatile blood flow signals owns a long tradition in oriental medicine. The secrets of pulse diagnosis have been partially explained by anatomy and hemodynamic analysis in contemporary western medicine. Now it is possible to obtain pulsatile blood flow signals by means of various mechanical, photoelectrical, and acoustic transducers. Meanwhile, with the introduction of advanced signal processing methods, pulsatile blood flow signals have exhibited great potentials to reveal intrinsic pathophysiological condition of cardiovascular system. Therefore, sphygmogram analyzers based on pulse signal monitoring and analysis have been proposed for health prognosis of cardiovascular system in home health monitoring. This paper is aimed to review methods and systems for pulse signal monitoring and analysis in a tutorial manner.
