Expert Answer:

  • Oxygen consumption and cardiac output in infants and children is three times those of adults on a body weight basis.
  • Due to the high oxygen affinity of fetal hemoglobin, the oxygen unloading capacity of hemoglobin in infants is about 50% less than in adults. 
  • Hence, infants and children require more RBCs to bind to more oxygen in the body.
