Abstract
The present invention relates to a device and a method for detecting a feature of an arterial blood pressure (ABP) waveform. The feature detecting method of an ABP waveform according to an exemplary embodiment of the present invention includes: searching a peak and a trough; detecting a systolic peak based on a time interval between a peak and a neighboring peak and an average pressure value; detecting a pulse onset with respect to a trough directly before the systolic peak; extracting a candidate of a dicrotic notch based on a magnitude of the systolic peak and a measurement time; detecting a point having a lowest pressure value among candidates of the dicrotic notch as a dicrotic notch and detecting a dicrotic peak based on the dicrotic notch; and classifying the detected dicrotic notches into a normal notch and a transient notch.
