Definition of Return of Spontaneous Circulation (ROSC)

Return of Spontaneous Circulation (ROSC)

Return of Spontaneous Circulation (ROSC) is the restoration of a sustained, effective heartbeat and pulse after resuscitation from cardiac arrest. It is signaled by a palpable pulse, a rise in end-tidal CO2 on capnography, and a measurable blood pressure, indicating that the heart is once again pumping blood on its own.

ROSC is a critical milestone, but it is not the end of treatment — the patient remains highly vulnerable and requires immediate post-resuscitation care to stabilize breathing and circulation, identify the cause of the arrest, and protect the brain. Achieving and maintaining ROSC is a central goal of the advanced life support algorithms.
