DEVICE AND METHOD FOR DETECTING ARTERIAL BLOOD PRESSURE WAVEFORM FEATURES

摘要

The present invention relates to a device and a method for detecting arterial blood pressure waveform features. A method for detecting arterial blood pressure waveform features, according to an embodiment of the present invention, comprises the steps of: investigating peaks and troughs; detecting a systolic peak on the basis of the average pressure value and the time gap between a peak and an adjacent peak; detecting a pulse onset on the basis of the trough immediately before the systolic peak; extracting dicrotic notch candidates on the basis of the measured time and the size of the systolic peak; detecting as a dicrotic notch a point having the lowest pressure value among the dicrotic notch candidates and detecting a dicrotic peak on the basis of the dicrotic notch; and classifying the detected dicrotic notch as a normal notch or a transient notch.
