ROSC stands for which of the following?

• A. Return of Spontaneous Circulation
• B. Rapid Onset of Circulation
• C. Return of Systemic Circulation
• D. Resuscitation Of Spontaneous Circulation

Answer: (A)

In resuscitation, the key idea is that the patient has regained an effective, self-generated heartbeat and perfusion after cardiac arrest. This is what "Return of Spontaneous Circulation" means: the heart is beating on its own again and able to maintain blood flow to vital organs, evidenced by a palpable pulse and a perfusing blood pressure. It’s more than a momentary rhythm on a monitor; it reflects actual circulation without ongoing chest compressions. Other phrasings aren’t standard terminology for this concept. Rapid Onset of Circulation, Return of Systemic Circulation, and Resuscitation Of Spontaneous Circulation don’t capture the established definition used in CPR and anesthesia practice.
