Brain Elastic Parameters and Cerebral Hemodynamics in Hemorrhagic Hypotension

  • Conference paper
Intracranial Pressure V

Abstract

Our previous studies indicated that brain elastic behavior was sensitive to changes in cerebral hemodynamics (Schettini and Ebbers 1980, Schettini and Fitzer 1981). The major criticism of our work has been that calculation of brain elastance by graphic analysis could be erratic because of subjective interpretation. We have overcome this by developing a logarithmic function. From our equation we derive the two elastic moduli of the brain: the first order of modulus (Initial tangent, ¯Go) and the second order of modulus (Initial curvature, ¯Go) which is the quantitative index of non-linearity of brain elastic behavior.
