What is the normal arterial oxygen saturation range for neonates?

The normal arterial oxygen saturation range for neonates typically falls between 95-98%. This range is considered ideal because it indicates that the neonate is effectively oxygenating their blood, which is crucial for their overall health and development. Maintaining adequate oxygen saturation is vital for organ function and metabolic processes, especially in the early days of life when neonates are adapting to breathing air for the first time after being in a womb environment.

While saturation levels below this range can be indicative of potential respiratory issues or inadequate oxygen delivery, levels that are consistently above can also suggest hyperoxia, which may lead to oxidative stress. Therefore, the 95-98% range is the target to ensure proper oxygenation without the risks associated with both low and excessively high oxygen levels.
