Measuring Blast-Related Intracranial Pressure Within the Human Head

Abstract

The goal of this research effort is to determine the transient responses of the skull-brain system during exposure to blast to help identify the primary mechanism of blast-TBI. The aims of this proposal are (1) to ascertain the relationship between magnitude levels of incident pressure and values of intracranial pressure, surface strain, and kinematic response, (2) to investigate the effects of orientation on all three parameters, and (3) to compare pressure distribution patterns with a finite element model. Preliminary data indicate there are significant factors of paramount importance when performing ICP-PMHS testing: sensor location in the brain, exposure at blast, orientation of head and magnitude of the blast. Work in the remaining six months will consist of final PMHS testing and finite element modeling.
