ROSC stands for Return of Spontaneous Circulation. Which of the following statements correctly matches an acronym?

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

Answer: (A)

Return of Spontaneous Circulation is the standard term used after cardiac arrest when the patient’s own heart starts beating again and effective blood flow resumes after resuscitation efforts. This option correctly captures the meaning of ROSC: the circulation has been restored spontaneously, not merely maintained by ongoing chest compressions or external support. The other phrasings don’t reflect the common meaning or wording of the acronym—rapid onset focuses on speed rather than the actual return of the heart’s own activity, recovery of systemic circulation is not the conventional expansion, and resuscitation of spontaneous circulation mixes processes with the outcome and isn’t the standard term.
