What are considered the most effective therapies for cardiac arrest?

• A. Early CPR and defibrillation
• B. High-flow oxygen administration alone
• C. Epinephrine infusion without CPR
• D. Defibrillation without CPR

Answer: (A)

The main idea here is that sustaining blood flow to the brain and heart while rapidly correcting the heart’s rhythm offers the highest chance of survival in cardiac arrest. High-quality CPR keeps circulation going, preserving organ perfusion and buying time for a defibrillator to restore a normal rhythm. Defibrillation is crucial when the arrest rhythm is shockable, and delivering a shock as soon as possible gives the heart the best chance to restart with an organized beat. Oxygen administration alone doesn’t restart circulation, and giving medications like epinephrine without CPR doesn’t improve outcomes as much as combining CPR with early defibrillation. Defibrillation without CPR misses the ongoing perfusion need, so the combination of immediate CPR and early defibrillation is the most effective overall.
