摘要：

Conventional measurements of oxygenation used in the critical care of sick newborn infants are limited to arterial blood. This approach fails to describe fully the physiological economy of oxygen in terms of supply (systemic oxygen transport), demand (oxygen consumption), or functional reserve (mixed venous oxygen content). The relationship between supply and demand can be described by the fractional oxygen uptake, which can be determined from arterial (S(a)O2) and mixed venous (S(vBAR)O2) oxygen saturations.
