What is the role of supplemental oxygen upon achieving ROSC when delivering CPR to a child?

Following the return of spontaneous circulation (ROSC) after CPR, the primary role of supplemental oxygen is to ensure that the child's oxygen saturation reaches a normal level, which is crucial for adequate tissue perfusion and recovery. Maintaining normal oxygen saturation reduces the risk of further complications related to hypoxia.

Utilizing supplemental oxygen helps to quickly restore adequate oxygen levels in the bloodstream, which can be especially vital in a post-cardiac arrest scenario where the child's body may still be recovering from the effects of prolonged oxygen deprivation. Monitoring oxygen saturation with a pulse oximeter can guide the amount of supplemental oxygen needed to achieve a saturation level usually between 94-99%.

Other approaches, such as inducing hyperoxygenation, could risk oxygen toxicity, and there is no need for arbitrary use of available oxygen supplies without regard for saturation levels. Inappropriate use of oxygen can either lead to inadequate oxygenation or excessive oxygen levels, both of which can be harmful. Therefore, following facility protocols is essential to ensure both accuracy and safety in oxygen delivery after ROSC.
