| Popis: | Cerebral perfusion pressure (CPP), defined as the difference between mean arterial blood pressure (MABP) and intracranial pressure (ICP), determines cerebral blood flow (CBF). In the intact brain, coupling between metabolic demand and substrate supply ensures adequate CBF over a wide range of CPP. Within the range of autoregulation, changes in cerebral vascular resistance (CVR) enable adequate CBF in spite of falling CPP. The minimal adequate CPP in adults has been reported to be 40 mm Hg (Miller et al. 1972) and 30 mm Hg in newborn infants (Raju et al. 1982). |
