Change in cardiac output (%) from control values during reduction in uterine blood flow resulting in hypoxemia in fetal sheep. Illustrates the redistribution of cardiac output to the brain, adrenals and heart at the expense of other organs. Data from Jensen, A., C. Roman, and A.M. Rudolph, Effects of reducing uterine blood flow on fetal blood flow distribution and oxygen delivery. J Dev Physiol., 1991. 15(6): p. 309–23.
