Comorbidities are a hallmark of stroke that both increase the incidence of stroke and worsen
outcome. Hypertension is prevalent in the stroke population and the most important …

The need of blood flow to different organs varies rapidly over time which is why there is
sophisticated local regulation of blood flow. The term dysregulation simply means that blood …

OBJECTIVE: Cerebrovascular vasomotor reactivity reflects changes in smooth muscle tone
in the arterial wall in response to changes in transmural pressure or the concentration of …

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 …

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 …

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

Background: Studies in animals have demonstrated that optic nerve head (ONH) blood flow
(F onh) is autoregulated, but there is a lack of evidence for such a process in humans …

We investigated dynamic cerebral pressure autoregulation awake and during 1.5 minimum
alveolar anesthetic concentration (MAC) sevoflurane or isoflurane anesthesia in 16 patients …

✓ The authors studied 31 comatose head-injured patients to assess the clinical usefulness
of laser Doppler flowmetry (LDF) in continuous autoregulation monitoring. The LDF probes …

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 …
