Background and Purpose A simple method of testing cerebral autoregulation by observing
transcranial Doppler changes in middle cerebral artery flow velocity (FV) during a brief …

The process of cerebral vessels regulating constant cerebral blood flow over a wide range of
systemic arterial pressures is termed cerebral autoregulation (CA). Static and dynamic …

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 …

The functional relationship between dynamic cerebral autoregulation (CA) and arterial
baroreflex sensitivity (BRS) in humans is unknown. Given that adequate cerebral perfusion …

The two common carotid arteries (anterior circulation) and the two vertebral arteries
(posterior circulation) supply blood to the anterior and posterior parts of the brain …

Background: Dynamic cerebral autoregulation (DCA) is the continuous counterregulation of
cerebral blood flow to fluctuations in blood pressure. DCA can become impaired after acute …

OBJECTIVE: To test the hypothesis that preeclampsia is associated with impaired dynamic
cerebral autoregulation. METHODS: In a prospective cohort analysis, cerebral blood flow …

Cerebral Autoregulation (CA) is an important physiological mechanism stabilizing cerebral
blood flow (CBF) in response to changes in cerebral perfusion pressure (CPP). By …

Cerebral perfusion pressure (CPP) is normally expressed by the difference between mean
arterial blood pressure (MAP) and intracranial pressure (ICP) but comparison of the …

Background—The effect of orthostatic stress on dynamic cerebral autoregulation (CA) in
normal subjects and patients with recurrent vasovagal syncope (VVS) is unclear. This study …
