BACKGROUND AND PURPOSE This study examined changes in cross-sectional area of the middle cerebral artery as assessed by changes in Doppler signal power during hypoxia and hypercapnia. In addition, it examined the degree of consistency among three indexes of cerebral blood flow and velocity: the velocity spectral outline (VP), the intensity-weighted mean velocity (VIWM), and an index of middle cerebral artery flow (P. VIWM). P. VIWM was calculated as the product of VIWM multiplied by the total… CONTINUE READING
