What does ROSC stand for in cardiac arrest?

• A. Return of Spontaneous Circulation
• B. Resting Oxygen Saturation Control
• C. Rhythmic Oscillation of Sinoatrial Node
• D. Rate Of Sinus Circulation

Answer: (A)

ROSC stands for Return Of Spontaneous Circulation. It marks the moment during resuscitation when the heart begins beating on its own again and can sustain blood flow to vital organs without ongoing chest compressions. Clinically, ROSC is suggested by a detectable pulse, measurable blood pressure, and signs of adequate perfusion. Reaching ROSC shifts focus from active resuscitation to post-arrest care, including airway and oxygenation optimization, hemodynamic support, and targeted temperature management. The other phrases don’t describe this milestone because they don’t convey the restoration of the heart’s own pumping and systemic perfusion.
