Autoregulation of Cerebral Blood Flow
Autoregulation of cerebral blood flow (constant perfusion despite variations in blood pressure) was studied in 15 control subjects and in 24 patients with cerebral vascular lesions. Thirteen patients were studied within the first 2 days of an episode of cerebral ischemia ("acute" group); 11 were studied from 15 days to several months after an ischemic episode ("chronic" group). Measurements of ...
متن کاملBrief Review Autoregulation of Blood Flow
A UTOREGULATION of blood flow, the tenden/ \ cy for blood flow to remain constant despite A. \ . changes in arterial perfusion pressure, is a ubiquitous and much studied phenomenon. Autoregulation was first described in the kidney in 1931, but it had been anticipated by Bayliss 30 years earlier based on changes in hind limb volume during alterations in arterial pressure. Bayliss noted a seconda...
متن کاملMolecular Mechanisms of Renal Blood Flow Autoregulation
Diabetes and hypertension are the leading causes of chronic kidney disease and their incidence is increasing at an alarming rate. Both are associated with impairments in the autoregulation of renal blood flow (RBF) and greater transmission of fluctuations in arterial pressure to the glomerular capillaries. The ability of the kidney to maintain relatively constant blood flow, glomerular filtrati...
متن کاملAutoregulation of blood flow by oxygen lack.
Ross, JOE M., HILTON M. FAIRCHILD, JOE WELDY, AND ARTHUR C. GUYTON. Autoregulation of blood flow by oxygen lack. Am. J. Physiol. 202(1): 2 r-24. Ig62.-The effect of hemoglobin oxygen saturation upon blood flow through the hind leg of the dog was studied by perfusing the femoral arteries of five normal dogs with blood, the oxygen saturation of which was varied between 100% and o%, and by perfusi...
متن کاملAutoregulation of Blood Flow: Vessel Diameter Changes in Response to Different Temperatures
Background: Autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. Although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. The biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...
