What is the next step after achieving ROSC for a patient with a BP of 72/40 following the administration of 250mL NS?

Achieving return of spontaneous circulation (ROSC) is a critical milestone in resuscitation efforts, but it does not guarantee stability, especially if the patient exhibits significant hypotension, as indicated by a blood pressure of 72/40. In this scenario, despite the administration of 250mL of normal saline, the patient's blood pressure remains low, suggesting that additional measures are necessary to achieve adequate perfusion.

The administration of push-dose epinephrine is a key intervention in this context. Push-dose epinephrine is used to temporarily increase blood pressure and cardiac output in patients who are hypotensive after achieving ROSC. It acts rapidly, which is crucial in stabilizing the patient while additional assessments and interventions are planned. By increasing systemic vascular resistance through vasoconstriction, epinephrine helps improve perfusion pressure to vital organs.

In contrast, simply increasing the NS infusion or administering additional fluids may not address the underlying issue of vascular tone and systemic vascular resistance in a hypotensive patient. While fluid resuscitation is vital, it may not be sufficient alone to restore circulation, particularly if fluid responsiveness has been exhausted or if there is significant ongoing shock.

Starting CPR again would only be indicated if the patient were to lose pulses again after having achieved
