Intracranial Pressure of Patients after Severe Traumatic Brain Injury: a Pilot Study for Lethality Estimation from Time Series

Intracranial pressure (ICP) belongs among relevant physiological parameters that are advised to be monitored at emergency units with patients after severe traumatic brain injury. However no advanced tools in a form of alarm based on ICP time series were developed. Procedure for assessment regarding actual degree of lethality is presented. ICP time segments and its derived features are applied into Gaussian mixture model in order to form vital and lethal clusters. From consecutive processing of time evolution of posterior probabilities a monitoring tool for each patient is built. New form of alarm may attract attention of medical stuff in order to adopt appropriate intervention for patients’ stabilization.
