Cerebral Blood Flow Influence of Changes in Blood Pressure on Cerebral Perfusion and Oxygenation
Cerebral autoregulation (CA) is a critical process for the maintenance of cerebral blood flow and oxygenation. Assessment of CA is frequently used for experimental research and in the diagnosis, monitoring, or prognosis of cerebrovascular disease; however, despite the extensive use and reference to static CA, a valid quantification of “normal” CA has not been clearly identified. While controlli...
متن کاملCorrelation between Cerebral Hemodynamic and Perfusion Pressure Changes in Non-Human Primates.
The mechanism that maintains a stable blood flow in the brain despite changes in cerebral perfusion pressure (CPP), and therefore guaranties a constant supply of oxygen and nutrients to the neurons, is known as cerebral autoregulation (CA). In a certain range of CPP, blood flow is mediated by a vasomotor adjustment in vascular resistance through dilation of blood vessels. CA is known to be impa...
متن کاملRelationships between cerebral perfusion pressure and regional cerebral blood flow in patients with severe neurological disorders.
Relationships Between Cerebral Perfusion Pressure and Regional Cerebral Blood Flow in Patients With Severe Neurological Disorders • Three patients, one with a recurrent brain tumor, one with a severe brain contusion, and one with a brain abscess, are described who had continuous monitoring of the intracranial pressure with epidural and/or ventricular pressure transducers, continuous monitoring ...
متن کاملRed blood cell deformability related to perfusion pressure in cerebral infarction with and without hypertension.
reasons: (1) Hemorrhagic infarctions may sometimes form a massive hematoma4; (2) The patient had no other apparent predisposing factors responsible for the lobar ICH5,6; (3) The ICH in the parietal lobe was within the vascular territory of the affected artery; and (4) The coexisting right temporal lesion was also a hemorrhagic infarction within the same vascular territory. We suggest that cervi...
متن کاملStrategies to meet lower blood pressure goals with a new standard in angiotensin II receptor blockade.
The continued poor rates of blood pressure (BP) control to the recommended target BP of <140/90 mm Hg in patients with hypertension indicate a persistent need for improved antihypertensive therapy. Angiotensin II receptor blockers (ARBs) constitute the newest approved class of antihypertensive agents. As with angiotensin converting enzyme inhibitors, ARBs block the renin-angiotensin-aldosterone...
