Early Relative Hypotension Below Noninvasive Cerebral Oximetry-Derived Optimal Blood Pressure Thresholds in Aneurysmal Subarachnoid Hemorrhage: A Pilot Study

Impairment in cerebral autoregulation (CA) after aneurysmal subarachnoid hemorrhage (aSAH) is associated with delayed cerebral ischemia (DCI) and poor outcomes. We assessed: 1) feasibility of defining CA-based optimal mean arterial pressure (MAP Opt ) thresholds using noninvasive cerebral oximetry a...
