Cerebral pressure autoregulation and carbon dioxide reactivity during propofol-induced EEG suppression [PDF]

, 2017
We studied cerebral pressure autoregulation and carbon dioxide reactivity during propofol-induced electrical silence of the electroencephalogram (EEG) in 10 patients.

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Bilateral dynamic cerebral autoregulation assessment during endovascular treatment in large‐vessel occlusion stroke

Experimental Physiology, EarlyView.
Abstract Recanalization by endovascular treatment (EVT) is effective in acute ischaemic stroke caused by large‐vessel occlusion. Better understanding of the pathophysiology could possibly identify targets for improving peri‐procedural management and thereby patient outcome.

Compromised Dynamic Cerebral Autoregulation in Patients With Depression

Frontiers in Psychiatry, 2019
Background: Patients with depression tend to have various comorbid neurological symptoms, but the mechanisms remain unclear. The purpose of this study was to analyze the characteristics of dynamic cerebral autoregulation in depressed patients.Methods ...

Cerebral autoregulation is compromised during simulated fluctuations in gravitational stress [PDF]

, 2018
Gravity places considerable stress on the cardiovascular system but cerebral autoregulation usually protects the cerebral blood vessels from fluctuations in blood pressure.

Whole‐body hot water immersion effect on cerebral haemodynamics and subsequent cerebrovascular reactivity to carbon dioxide

Experimental Physiology, EarlyView.
Abstract To test the hypothesis that hot water immersion (HWI) improves cerebrovascular function via shear‐mediated mechanisms, this study determined cerebrovascular reactivity to carbon dioxide (CVRCO2${\mathrm{CV}}{{\mathrm{R}}_{{\mathrm{C}}{{\mathrm{O}}_2}}}$) before and after 60 min of 39°C HWI and a 21°C air control (CON) in 15 healthy ...

Acute management of poor condition subarachnoid hemorrhage patients [PDF]

, 2012
Poor condition subarachnoid hemorrhage (SAH) patients present a high mortality and morbidity. In this study, we reviewed the acute interventional (surgical and endovascular) management of 109 SAH-poor condition patients, who were treated as early as ...

Extended model of impaired cerebral autoregulation in preterm infants: Heuristic feedback control

Mathematical Biosciences and Engineering, 2019
Cerebral autoregulation is the ability to keep almost constant cerebral blood flow (CBF) for some range of changing the mean arterial pressure (MAP). In preterm infants, this range is usually very small, even absent, and a passive (linear) dependence of ...
