    Three-part question

    Patient group—(In adults admitted to the ED with an out-of-hospital cardiac arrest)

    Intervention—(does end tidal CO2 measurement)

    Outcome—(predict/prognosticate return of spontaneous circulation)?

    Clinical scenario

    A 60-year-old male is brought into the ED with an

    out-of-hospital cardiac arrest (OOHCA). All monitoring is attached while ALS protocol is ongoing, including CO2 monitoring. You want to assess whether the patient is going to survive and thereby achieve a return of spontaneous circulation (ROSC) and you wonder whether the patient’s end tidal CO2 (ETCO2) level can prognosticate this.
