Abstract

Traumatic brain injury (TBI) is an important public health problem worldwide. This paper introduces transfer entropy as a measure to identify any standard between arterial blood pressure and electrocardiogram signal for patients diagnosed with TBI. Therefore, we will review the basic definitions of information theory and transfer entropy, which interpretation is influenced not only by the Kullback-Leibler divergence, but also by conditioned mutual information. For transfer entropy measurement we used Kraskov-Stögbauer- Grassberger (KSG) technique. It is observed that directionality in transfer entropy can provide clinical decision support for TBI cases.
