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 ...

Frontiers in Neurology, 2021 The autoregulation of cerebral blood flow protects against brain injury from transient fluctuations in arterial blood pressure. Impaired autoregulation may contribute to hypoperfusion injury in neonates and infants.

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 ...

Differentiating Dynamic Cerebral Autoregulation Across Vascular Territories
Frontiers in Neurology, 2021 Objective: Transcranial Doppler is commonly used to calculate cerebral autoregulation, but measurements are typically restricted to a single cerebral artery.

Neonatal cerebrovascular autoregulation [PDF]
Pediatric Research, 2018 Cerebrovascular pressure autoregulation is the physiologic mechanism that holds cerebral blood flow (CBF) relatively constant across changes in cerebral perfusion pressure (CPP). Cerebral vasoreactivity refers to the vasoconstriction and vasodilation that occur during fluctuations in arterial blood pressure (ABP) to maintain autoregulation.

Existence analysis of power flow solution considering LVRT of a full-power converter
Zhejiang dianli, 2023 Power flow solution of the system with a full-power converter may get lost during low-voltage ride-through （LVRT）. Therefore， the change law of grid equivalent parameters and power flow characteristics during the fault is analyzed， and the law of ...

Frontiers in Neurology, 2021 Posterior circulation involves the vertebrobasilar arteries, which supply oxygen and glucose to vital human brainstem structures and other areas. This complex circulatory- perfusion system is not homogenous throughout the day; rather, its hemodynamic ...

Frontiers in Medicine, 2021 Background: Ischemic and hyperemic injury have emerged as biologic mechanisms that contribute to cognitive impairment in critically ill patients. Spontaneous deviations in cerebral blood flow (CBF) beyond ischemic and hyperemic thresholds may represent ...
