Researchers link blood flow regulation in the brain and prognosis following cardiac arrest

A group of researchers at Osaka University have used a noninvasive method to evaluate cerebrovascular autoregulation (CVAR) in patients following out-of-hospital cardiac arrest. The mortality rate increased significantly with the duration of time that CVAR was undetectable. The article, “Association between time-dependent changes in cerebrovascular autoregulation after cardiac arrest and outcomes: a prospective cohort study,” was published in Journal of Cerebral Blood Flow and Metabolism.
