Abstract
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.
- DO2, oxygen delivery
- FOE, fractional oxygen extraction
- Hbflow, haemoglobin flow
- MAP, mean arterial pressure
- NIRS, near-infrared spectroscopy
- SaO2, oxygen saturation (haemoglobin)
- SvO2, mixed venous oxygenation
- TOI, tissue oxygenation index
- VO2, oxygen consumption
