Abstract

Describes an offline detection algorithm for pressure signals that incorporates heart rate, amplitude, and interbeat intervals to identify the time location of four signal components. The algorithm performance was assessed based on the statistics of the interbeat intervals of the detected components. The algorithm performed well when applied to arterial blood pressure and intracranial pressure signals acquired from patients in a pediatric intensive care unit.
