Final answer:
Normal umbilical cord blood pH and blood gas values for term newborns are not directly provided for venous blood, but the reference values for arterial pH are 7.35-7.45, indicating a range for healthy blood gas levels. Venous levels vary slightly due to deoxygenation.
Step-by-step explanation:
The question being asked pertains to the normal umbilical cord blood pH and blood gas values in term newborns, specifically looking at venous blood. These values are critical indicators of a newborn's health immediately after birth. While the requested values for venous blood are not provided directly in the reference material, arterial blood gas reference values are available and typically, venous blood will have a slightly lower pH and higher pCO2 compared to arterial blood because it has been deoxygenated after circulating through the body.
For arterial blood in term newborns, reference values are pH: 7.35-7.45, pCO2: male: 35-48 mm Hg, female: 32-45 mm Hg, and total venous bicarbonate: 22-29 mM. It is crucial to recognize the changes occurring during birth, as the circulatory system undergoes significant reconfiguration when the newborn begins to breathe independently, and the umbilical cord vessels collapse and eventually become fibrotic.
