Brain function critically depends on a close matching between metabolic demands,
appropriate delivery of oxygen and nutrients, and removal of cellular waste. This matching …

Cerebral autoregulation is the intrinsic ability of the brain to maintain adequate cerebral
perfusion in the presence of blood pressure changes. A large number of methods to assess …

Traumatic brain injury (TBI) remains a significant source of death and permanent disability,
contributing to nearly one-third of all injury related deaths in the United States and exacting …

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 …

Transcranial Doppler (TCD) is a noninvasive ultrasound (US) study used to measure
cerebral blood flow velocity (CBF‐V) in the major intracranial arteries. It involves use of low …

Purpose Patients with dysautonomia often experience symptoms such as dizziness,
syncope, blurred vision and brain fog. Dynamic cerebral autoregulation, or the ability of the …

Regulation of the cerebral circulation relies on the complex interplay between
cardiovascular, respiratory, and neural physiology. In health, these physiologic systems act …

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 …

Cerebrovascular pressure autoregulation is the physiologic mechanism that holds cerebral
blood flow (CBF) relatively constant across changes in cerebral perfusion pressure (CPP) …

Background and Purpose—Individualizing mean arterial blood pressure targets to a
patient's cerebral blood flow autoregulatory range might prevent brain ischemia for patients …
