In the context of pediatric advanced life support, ROSC stands for "Return of Spontaneous Circulation." This term specifically refers to the restoration of effective blood circulation and perfusion following a cardiac arrest. Achieving ROSC is a critical goal in resuscitation efforts, as it indicates that the heart has begun to function effectively on its own after resuscitation measures have been applied.

When a child's heart stops, immediate and effective CPR can help maintain blood flow to vital organs, and advanced interventions may facilitate the resumption of a normal cardiac rhythm. The significance of recognizing ROSC lies in its implications for patient outcomes; it is a clear indicator that the initial life-saving measures have succeeded in reviving the child, allowing for further evaluations and necessary interventions to stabilize the patient.

In contrast, the other options do not accurately describe this vital concept in pediatric advanced life support. "Reversal of sudden cardiac" implies a specific intervention rather than a measurable outcome, "Rapid oxygen saturation change" addresses something different altogether concerning oxygen levels, and "Registered organ support care" does not align with standard terminology in resuscitation protocols.
