Cerebral blood flow, oxidative metabolism and cerebrovascular carbon dioxide reactivity in patients with acute bacterial meningitis

Background: The optimal arterial carbon dioxide tension (PaCO2) in patients with acute bacterial meningitis (ABM) is unknown and controversial. The objective of this study was to measure global cerebral blood flow (CBF), cerebrovascular CO2 reactivity (CO2R), and cerebral metabolic rates (CMR) of oxygen (O2), glucose (glu), and lactate (lac), in patients with ABM and compare the results to those obtained in healthy volunteers.
