Cord blood gases are typically drawn from the umbilicus during delivery to document oxygenation status of the newborn during delivery. Acidosis (pH less than 7.1 in an arterial cord blood gas) may indicate blood flow and hence oxygenation from mother to newborn may have been occluded during delivery. The Umbilical Artery is where the baby's venous circulation dumps unoxygenated blood. This is blood that was on its way back to the mom's heart and lungs to pick up oxygen.
After a baby is born and the umbilical cord. is cut, some blood remains in the blood. vessels of the placenta and the portion of. the umbilical cord that remains attached. to it. After birth, the baby no longer needs. this extra blood which is called umbilical. cord blood or ââcord bloodââ for short.
