A 230-volt incandescent light bulb, with a 'medium' sized E27 (Edison 27 mm) male screw base. The filament is visible as the horizontal line between the vertical supply wires. SEM image of a tungsten filament of incandescent light bulb. An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to a high temperature, by passing an electric current through it, until it glows with visible light (incandescence).
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.
If you want the blood stored, after the birth, the doctor clamps the umbilical cord in two places, about 10 inches apart, and cuts the cord, separating mother from baby. Then she inserts a needle and collects at least 40 milliliters of blood from the cord. The blood is sealed in a bag and sent to a lab or cord blood bank for testing and storage. The process only takes a few minutes and is painless for mother and baby. The cord blood bank may also send tubes so that the motherâs blood can be taken, too.
