During apneic periods, what is a significant concern for neonates?

In neonates, a significant concern during apneic periods is their limited oxygen reserves. Unlike older children and adults, neonates have a smaller functional residual capacity and reduced ability to store oxygen in their lungs. This limitation means that when they experience apneic episodes, they can quickly desaturate, leading to hypoxemia.

Neonates rely heavily on continuous oxygen delivery to meet their metabolic needs due to their immature respiratory systems and high oxygen demands relative to their body size. Therefore, any interruption in breathing can lead to serious physiological consequences, as there is a minimal buffer of oxygen available in their system. This highlights the critical nature of monitoring and managing respiratory function in this vulnerable population during sedation or any medical procedure.
