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

Cerebral autoregulation (CA) is integral to the delicate process of maintaining stable
cerebral perfusion and brain tissue oxygenation against changes in arterial blood pressure …

To test the hypothesis that spontaneous changes in cerebral blood flow are primarily
induced by changes in arterial pressure and that cerebral autoregulation is a frequency …

Abstract FORTY-FIVE MEASUREMENTS of diameters of 12 human cerebral arteries were
performed during 10 craniotomies under moderate changes in mean blood pressure and …

Blood flow (BF) increases with increasing exercise intensity in skeletal, respiratory, and
cardiac muscle. In humans during maximal exercise intensities, 85% to 90% of total cardiac …

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

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 …

✓ The purpose of this study was to determine whether patients with minor head injury
experience impairments in cerebral autoregulation. Twenty-nine patients with minor head …

The examination of blood flow velocity (BFV) changes during the performance of mental
tasks is one of the applications of transcranial Doppler (TCD) ultrasonography. The purpose …

This study validates transcranial Doppler sonography (TCD) for determination of the lower
limit of cerebral blood flow (CBF) autoregulation and establishes a relation between global …
