Cerebral Autoregulation in Subarachnoid Hemorrhage [PDF]
Frontiers in Neurology, 2021 Subarachnoid hemorrhage (SAH) is a devastating stroke subtype with a high rate of mortality and morbidity. The poor clinical outcome can be attributed to the biphasic course of the disease: even if the patient survives the initial bleeding emergency ...

Bioelectrical Impedance-Based Time-Domain Analysis for Cerebral Autoregulation Assessment [PDF]
SensorsCerebral autoregulation refers to the ability of cerebral vasculature to maintain stable blood flow by adjusting vascular resistance in response to changes in perfusion pressure.

Impaired Cerebral Autoregulation in Children. [PDF]
Pediatr NeurolManaging acute brain injury involves protecting the brain from secondary injury by addressing the mismatch between metabolic demand and cerebral perfusion. Observational studies have associated impaired cerebral autoregulation, a physiological process governing the regulation of cerebral blood flow, with unfavorable neurological outcomes in both ...

BJA Open, 2022 Background: Cerebral autoregulation actively maintains cerebral blood flow over a range of MAPs. During general anaesthesia, this mechanism may not compensate for reductions in MAP leading to brain hypoperfusion.

Modeling of Cerebral Blood Flow Autoregulation Using Mathematical Control Theory
Mathematics, 2022 A mathematical model of cerebral blood flow in the form of a dynamical system is studied. The cerebral blood flow autoregulation modeling problem is treated as a nonlinear control problem and the potential and applicability of the nonlinear control ...

Cerebral Autoregulation in Man [PDF]
Stroke, 1974 Autoregulation was tested by regional blood flow (rCBF) and cardiohemodynamic measurements before and after induced systemic arterial hypertension in 16 patients with varying neurological disorders. Hypertension was induced by increasing the arterial blood pressure by an intravenous infusion of Aramine.
