ESTIMATION OF THE PROBABILITY OF HEAD INJURY AT A GIVEN ABBREVIATED INJURY SCALE LEVEL BY MEANS OF A FUCTION OF HEAD INJURY CRITERION

Abstract

The paper presents a review of the basic literature on the determination of head injury effects. Introduction to the subject of Head Injury Criterion (HIC) applications as likelihood of head injury measures was made. Individual levels of Abbreviated Injury Scale (AIS) were listed as a representation of the consequences of head injury. Prasad and Mertz curves describing the relationship between the HIC value and the probability of injury for a given AIS level were presented. Exponential models, developed by the authors, representing individual curves were presented. The probability of head injuries at different AIS levels was estimated for selected case studies presented in the literature devoted to human workplace safety. The analysis was concluded with debate and conclusions on the use of the proposed models.
