Noninvasive Monitoring of Dynamic Cerebrovascular Autoregulation and ‘Optimal Blood Pressure’ in Normal Adult Subjects

Background Cerebrovascular autoregulation can be continuously monitored from slow fluctuations of arterial blood pressure (ABP) and regional cerebral oxygen saturation (rSO2). The purpose of this study was to evaluate the index of dynamic cerebrovascular autoregulation (TOx) and the associated ‘optimal’ ABP in normal adult healthy subjects.
