Forearm and Calf Tissue Oxygenation in Term Neonates Measured with Near-Infrared Spectroscopy
J Physiol Sci Vol.57, No.5 pp.317-319
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.
