Oxygen saturation targets for preterm infants in the delivery room.

Fetal life evolves in a low oxygen milieu as compared to the extra-uterine. In the fetal to neonatal transition rapid changes in the oxygen content of the newly born infant occur within a brief period of time. Delivery room care givers should be aware of the slow transition regarding oxygenation, and supply oxygen as needed trying to avoid damage caused by hyper-and-hypoxia.

The use and misuse of oxygen during the neonatal period.

This article describes aerobic metabolism, oxygen free radicals, antioxidant defenses, oxidative stress, inflammatory response and redox signaling, the fetal to neonatal transition, arterial oxygen saturation, oxygen administration in the delivery room, oxygen during neonatal care in the NICU, evolving oxygen needs in the first few weeks of life, and complications that can occur when infants go home from the hospital on oxygen.
