Peripheral Oxygenation in Term Neonates

Pichler G, Grossauer K, Klaritsch P, et al. Peripheral oxygenation in term neonates. Arch Dis Child Fetal Neonatal Ed. 2007;92(1):F51–F52. doi:10.1136/adc.2005.089037

The aim of this study was to analyse changes in peripheral oxygenation in healthy term neonates within the first week of life with near‐infrared spectroscopy and venous occlusion. Oxygen delivery did not change with increasing age. Oxygen consumption and fractional oxygen extraction increased, whereas tissue oxygenation index decreased with increasing age.

Near‐infrared spectroscopy (NIRS), in combination with venous occlusion, enables measurements of peripheral oxygenation and perfusion.1,2,3 In the present study, we carried out repeated measurements of peripheral oxygenation in healthy term neonates within the first week of life. The aim was to analyse changes in oxygen delivery (DO2), oxygen consumption (VO2), fractional oxygen extraction (FOE), tissue oxygenation index (TOI), mixed venous oxygenation (SvO2), haemoglobin flow (Hbflow) and vascular resistance, to obtain normal values.
