Background and Purpose—Cerebral autoregulation may become impaired after stroke. To
provide a review of the nature and extent of any autoregulation impairment after stroke and …

Cerebral autoregulation (CA) refers to the properties of the brain vascular bed to maintain
cerebral perfusion despite changes in blood pressure (BP). Whereas classic studies have …

Background and Purpose Cerebral autoregulation can be evaluated by measuring relative
blood flow changes in response to a steady-state change in the blood pressure (static …

✓ Early results using cerebral perfusion pressure (CPP) management techniques in persons
with traumatic brain injury indicate that treatment directed at CPP is superior to traditional …

Assessment of cerebral autoregulation is an important adjunct to measurement of cerebral
blood flow for diagnosis, monitoring or prognosis of cerebrovascular disease. The most …

Background and Purpose—Under normal circumstances, autoregulation maintains cerebral
blood flow (CBF) constant within a wide range of mean arterial pressure (MAP). It remains …

During exercise regional cerebral blood flow (rCBF), as blood velocity in major cerebral
arteries and also blood flow in the internal carotid artery increase, suggesting an increase in …

Background Although inhalation anesthetic agents are thought to impair cerebral
autoregulation more than intravenous agents, there are few controlled studies in humans …

During standing, both the position of the cerebral circulation and the reductions in mean
arterial pressure (MAP) and cardiac output challenge cerebral autoregulatory (CA) …

Background and Purpose This study investigates the usefulness, as a test of dynamic
autoregulation, of phase shift angle analysis between oscillations in cerebral blood flow …
