Effects of heat stress on dynamic cerebral autoregulation during large fluctuations in arterial blood pressure.
Impaired cerebral autoregulation during marked reductions in arterial blood pressure may contribute to heat stress-induced orthostatic intolerance. This study tested the hypothesis that passive heat stress attenuates dynamic cerebral autoregulation during pronounced swings in arterial blood pressure. Mean arterial blood pressure (MAP) and middle cerebral artery blood velocity were continuously ...
متن کاملDynamic cerebral autoregulation in acute lacunar and middle cerebral artery territory ischemic stroke.
BACKGROUND AND PURPOSE We addressed whether dynamic cerebral autoregulation (dCA) is affected in middle cerebral artery (MCA) territory (MCAS) and lacunar ischemic stroke (LS). METHODS Blood pressure (MAP) and MCA velocity (V) were measured in 10 patients with large MCAS (National Institutes of Health Stroke score, 17+/-2; mean+/-SEM), in 10 with LS (score, 9+/-1), and in 10 reference subject...
متن کاملInfluence of noninvasive peripheral arterial blood pressure measurements on assessment of dynamic cerebral autoregulation.
Assessment of dynamic cerebral autoregulation (CA) requires continuous recording of arterial blood pressure (ABP). In humans, noninvasive ABP recordings with the Finapres device have often been used for this purpose. We compared estimates of dynamic CA derived from Finapres with those from invasive recordings in the aorta. Measurements of finger noninvasive ABP (Finapres), intra-aortic ABP (Mil...
متن کاملEffects of hypobaric hypoxia on cerebral autoregulation.
BACKGROUND AND PURPOSE Acute hypoxia is associated with impairment of cerebral autoregulation (CA), but it is unclear if altered CA during prolonged hypoxia is pivotal to the development of cerebral pathology, such as that seen in acute mountain sickness (AMS). This investigation evaluated relationship between CA and AMS over 9 hours of hypobaric hypoxia. METHODS Fifty-five subjects (41 males...
