The total fetal cardiac output at term is estimated to be ______?: (A) 150 mL/Kg body weight, (B) 250 mL/Kg body weight, (C) 350 mL/Kg body weight, (D) 450 mL/Kg body weight
Answer is D. The total fetal cardiac output is approximately 450 mL/Kg/min. Approximately 65% of descending aoic blood flow returns to the placenta, and hence, only the remaining 35% perfuses the fetal organs and tissues. Ref: Nelson textbook of pediatrics 21st edition Pgno: 9260
