This matching requires continuous regulation of cerebral blood flow (CBF), which can be categorized into four broad topics: 1) autoregulation, which describes the response of the … WebAbstract. The cerebral circulation is tightly regulated to meet the brain's metabolic demands. Although the mechanism is not fully understood, the major physiologic influences on cerebral blood flow have been well documented. In this chapter the basic vascular anatomy, and physiologic control of the cerebral circulation are reviewed. 3b pachuca WebMar 16, 2024 · CMRO 2 is derived from measurable parameters, exploiting Fick’s Principle, CMRO 2 = C a · CBF · (SaO 2 –SvO 2), with C a being the oxygen carrying capacity of blood, CBF the cerebral blood flow, expressed in units of blood volumetric flow per unit time and mass, and SaO 2 and SvO 2 representing the fractional arterial and venous …
