Cardiac Output and Cerebral Blood Flow: A Systematic Review of Cardio-Cerebral Coupling

Abstract: Control of cerebral blood flow (CBF) is crucial to the management of neurocritically ill patients. Small studies which have examined the role of cardiac output (CO) as a determinant of CBF have inconsistently demonstrated evidence of cardio-cerebral coupling. Putative physiological mechanisms underpinning such coupling include changes in arterial blood pressure pulsatility, which would produce vasodilation through increased oscillatory wall-shear-stress and baroreceptor mediated reflex sympatholysis, and chang… Show more

“…Central volume loading and unloading lead to parallel changes in cardiac output and cerebral blood flow [7], whereas phenylephrine treatment leads to divergent changes in cardiac output and cerebral blood flow. This proposition is supported by a comprehensive review that failed to establish an independent relationship between cardiac output and cerebral blood flow [103], probably because the data were pooled without stratification based on the origin of the cardiac output change.…”

“…Cardiac output directly influences CBF and cerebral oxygenation independently from changes in arterial blood pressure (Castle-Kirszbaum et al, 2022; Lie et al, 2021; Ogoh, Brothers, et al, 2005). In our study, cardiac output values during the sprints were moderately and positively correlated with ΔO 2 Hb and ΔtHb, which suggests that cardiac output might contribute to changes in CBF and cerebral oxygenation during the repeated sprints.…”

“…58 Other interesting reviews include opioid alternatives in spine surgery, the effects of anesthesia on glioma progression and cardiac-cerebral coupling. [59][60][61] Finally, there are the recent clinical practice guidelines from the Society for Neuroscience in Anesthesiology and Critical Care on Perioperative care of patients undergoing major complex spinal instrumentation surgery, and the guideline from the American Heart Association/American Stroke Association on the management of patients with spontaneous intracerebral hemorrhage. 62,63…”
