Motion Artifact Detection for Continuous Blood Pressure Monitor

Abstract: 

A method and apparatus is provided for detecting motion artifacts in data obtained from a blood pressure monitoring transducer and for preventing erroneous data related to such artifacts from interfering with the accuracy of the blood pressure measurement. Operation includes the steps of monitoring the amplitude of a pulse waveform from a first pulse to a next successive pulse and determining if the output signal changes by more than a predetermined percentage, thus indicating a motion condition.
