(A) Multiparameter mathematical model of wall tension (WTm) is used to demonstrate that wall tension is significantly correlated to cerebrovascular resistance (Ra) (P<0.001) at baseline levels of intracranial pressure (ICP), arterial blood pressure (ABP), and PaCO₂ (normocapnia). (B) Modeled wall tension is significantly correlated to PaCO₂ at baseline ICP and ABP. (C) Relationship between modeled vessel's wall tension and cerebral perfusion pressure cerebral perfusion pressure (CPP) (P=0.001).
