Cerebrovascular reserve (CVR) can be assessed by measuring the hemodynamic response to a physiological stress such as alteration of blood pressure, increase in tissue acidosis, lowered oxygen supply, increase in metabolic demand, or occlusion of an artery. Failure of the cerebrovascular system to maintain function or normative values of several interrelated hemodynamic variables--cerebral blood flow (CBF), oxygen extraction fraction (OEF), cerebral blood volume (CBV), and cerebral metabolic… CONTINUE READING
