What is the target oxygen saturation for a newborn after resuscitation?

The target oxygen saturation for a newborn after resuscitation is set between 85-95% in the first minutes of life. This range is critical because it indicates that the newborn is receiving an adequate level of oxygen without risking hyperoxia, which can cause damage to sensitive neonatal tissues.

In the immediate postnatal period, especially during resuscitation, a gradual increase in oxygen saturation is expected. Initially, lower saturations are permissible, but the goal is to achieve the 85-95% range as the newborn stabilizes. This range helps ensure that the infant's oxygenation is sufficient for metabolic needs while still allowing for the natural adaptation to breathing air, particularly in the context of adjusting from fetal life.

Monitoring oxygen saturation closely during this period is vital, as it provides immediate feedback on the effectiveness of resuscitation efforts, guiding healthcare providers in adjusting supplemental oxygen as necessary. This careful calibration helps avoid both inadequate oxygen delivery, which can lead to hypoxia, and excess oxygen, which can be harmful.
