Which option is NOT a listed clinical indication of ROSC?

• A. A Palpable Pulse
• B. A Measurable Blood Pressure
• C. A Sudden and Sustained Increase in ETCO2
• D. Persistent Bradycardia With No Pulse

Answer: (D)

When assessing return of spontaneous circulation, the signs you want are evidence that the heart is actively pumping blood again. A palpable pulse shows forward flow, and a measurable blood pressure confirms ongoing perfusion to the organs. An abrupt, sustained rise in end-tidal CO2 also supports ROSC because it reflects renewed pulmonary blood flow with circulating blood reaching the lungs. The scenario of persistent bradycardia with no pulse, however, means there is no effective cardiac output yet—circulation has not returned. So while the first three signs indicate ROSC, persistent bradycardia without a pulse does not.
