Monitoring Brain Injury With TSALLIS Entropy

Abstract

Nonextensive entropy measure, Tsallis Entropy (TE), was undertaken to monitor the brain injury after cardiac arrest. EEG of human and experimental injury model of rats are investigated. In both conditions TE decreases in bad physiological functional outcome. As the brain recovers from injury, the TE will also gradually return to normal level. Meanwhile, TE also shows good sensitivity to different grades of asphyxic injury. This method provides a novel real time brain injury indicator and may be a useful in developing a diagnostic monitoring tool.
