What is the normal range for oxygen saturation (SpO2) on room air (RA) in healthy late preterm and term infants by 24 hours of life?

In healthy late preterm and term infants by 24 hours of life, the normal range for oxygen saturation (SpO2) on room air is generally recognized to be between 95.6% and 98.8%. This range is important for ensuring that infants are receiving adequate oxygenation and functioning well after birth. Saturations within this range indicate that the infant's lungs are adequately oxygenating their blood and that they are adjusting well to breathing air outside the womb.

Lower saturation values may suggest problems with respiratory function, while values above this range may not be typical but could occur in very well oxygenated infants. Therefore, the choice that accurately reflects healthy SpO2 levels for this population in the specified time frame is essential for clinicians who monitor the health and development of newborns, ensuring prompt identification of any potential issues related to respiratory distress or other complications.

Understanding this normal range helps healthcare providers make informed decisions in the care of neonates during their critical first hours of life, ensuring they can respond appropriately if oxygen saturation levels fall outside of the expected parameters.
