Cerebral autoregulation is a homeostatic process that regulates and maintains cerebral
blood flow (CBF) constant across a range of blood pressures. The original concept was …

BACKGROUND: The cerebral perfusion pressure that denotes the lower limit of cerebral
blood flow autoregulation (LLA) is generally considered to be equivalent for reductions in …

Cerebral autoregulation describes a mechanism that maintains cerebral blood flow stable
despite fluctuating perfusion pressure. Multiple nonperfusion pressure processes also …

IMPLICATIONS: The moving correlation coefficients between slow changes of arterial blood
pressure and mean or systolic flow velocity, termed “Mx” and “Sx,” respectively, characterize …

Cerebral autoregulation (CA) is a protective mechanism that maintains cerebral blood flow
at a relatively constant level despite fluctuations of cerebral perfusion pressure or arterial …

Introduction Cerebral autoregulation (CA) is a theoretical construct characterized by the
relationship between mean arterial pressure (MAP) and cerebral blood flow (CBF). We …

Cerebral autoregulation reflects the ability of the brain to keep the cerebral blood flow (CBF)
relatively constant despite changes in cerebral perfusion pressure. It is an intrinsic …

This comprehensive review summarizes the evidence regarding use of cerebral
autoregulation-directed therapy at the bedside and provides an evaluation of its impact on …

Abstract In 1959, Niels Lassen illustrated the cerebral autoregulation curve in the classic
review article entitled Cerebral Blood Flow and Oxygen Consumption in Man. This concept …

There are occasionally intraoperative circumstances in which reduction of mean arterial
pressure (MAP) to levels well below those that occur in nonanesthetized adults is necessary …
