Fetal volumetric flow rate

After it was determined that changing the linear velocity of the maternal or fetal blood stream did not affect the equilibration pressure, it was possible to determine the maternal to fetal volumetric flow rate ratio that would result in an equilibration pressure which matched experimentally determined values of umbilical vein and artery oxygen partial pressures (37). As the maternal to fetal volumetric flow rate ratio is increased, the partial pressure of oxygen at which equilibration... 

Fetal Volumetric Flow Rate. During pregnancy the umbilical cord of the fetus may become partially or totally occluded if it becomes knotted or compressed against the body of the fetus. A study was made...
