Abstract:
Peripheral tissue oxygenation has been studied with near-infrared spectroscopy (NIRS) on either the forearm or calf with questionable comparability. The aim was to compare forearm and calf tissue oxygenation in healthy term neonates measured with NIRS. Fractional oxygen extraction, tissue oxygenation index, and mixed venous oxygenation were similar in both extremities, whereas oxygen delivery and oxygen consumption of calf tissue were higher.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
