Human umbilical vessel diameters and bloodgas tensions in the first two minutes after delivery.
Human umbilical vein and artery diameters reduce significantly during the first 2 min after delivery, whereas blood gas tensions do not change significantly. Gas tension changes, therefore, cannot account for the reduction in the umbilical vessel diameters which occurs during this time.
