If the heart rate remains below 60 after initial CPR, which medication is indicated?

• A. Epinephrine Infusion
• B. Epinephrine Bolus
• C. Amiodarone
• D. Push-Dose Epinephrine

Answer: (D)

When perfusion is still poor after initial CPR, the goal is to rapidly boost blood flow to the heart and brain. Push-dose epinephrine provides quick, easily titratable vasopressor support that you can give right away in small, repeatable doses. This short-acting approach helps raise the perfusion pressure during ongoing resuscitation, which can help the heart rate improve toward a more effective rhythm and increase the chances of ROSC. An epinephrine infusion takes time to prepare and set up, and while it’s valuable for ongoing support after ROSC or in longer resuscitations, it isn’t as immediate a tool during the immediate resuscitation phase as push-dose epinephrine. A single epinephrine bolus is less controllable for ongoing needs and might not sustain perfusion as well as repeated tiny doses. Amiodarone is used for certain rhythm problems like recurrent VT/VF, not for a bradycardic, poorly perfused scenario.
