... Netherlands. Abstract Background: The present study was undertaken to examine the feasibility of venous oxygen measurements in the inferior vena cava (IVC) via a catheter through the umbilical vein. This may serve as a proxy ... of oxygen for low birthweight infants causes retinopathy of prematu- rity, while extreme lack of oxygen leads to death. Chronic deficiency o...

In this particular case, one explanation is the diffe...
