Regulation of Cerebral Blood Flow [PDF]
International Journal of Vascular Medicine, 2011 The control of cerebral blood flow is complex, and only beginning to be elucidated. Studies have identified three key regulatory paradigms. The first is cerebral pressure autoregulation, which maintains a constant flow in the face of changing cerebral perfusion pressure.

On the Normalization of Cerebral Blood Flow [PDF]
Journal of Cerebral Blood Flow & Metabolism, 2013 Cerebral blood flow (CBF) is the most common parameter for the quantification of brain's function. Literature data indicate a widespread dispersion of values that might be related to some differences in the measurement conditions that are not properly taken into account in CBF evaluation.

Hyperventilation and Cerebral Blood Flow [PDF]
Stroke, 1972 Hypocapnic-hyperventilation has a profound, but probably temporary, effect on CBF, producing approximately a 2% decline in CBF for each 1 torr decline in P co co2 . This effect appears to be mediated through changes in perivascular pH of the cerebral resistance vessels ...

Systemic and cerebral blood flow [PDF]
Archives of Disease in Childhood - Fetal and Neonatal Edition, 2003 We read with interest the findings of Evans et al concerning the changes in middle cerebral artery (MCA) haemodynamics over the first two days after birth in preterm infants.1 Evans et al demonstrated a significant change in several Doppler velocity measures in the MCA, including systolic, diastolic, and mean velocity, pulsatility index and velocity ...

[Cerebral blood flow in infants: comparison of carotid blood flow and cerebral blood velocity].
No to hattatsu = Brain and development, 1990 Carotid blood was measured with a ultrasonic volume flow meter in 38 infants. The carotid blood flow was 1.50 +/- 0.55 ml/sec. At the same time peak systolic flow velocity, mean blood velocity, end diastolic velocity, pulsatility index (PI) and resistance index (RI) in the middle and anterior cerebral arteries were measured by duplex Doppler scanning ...
