Which arrangement best saves a life in sudden cardiac arrest: CPR and AED?

Explanation:
In sudden cardiac arrest, two actions work together to save a life: keep blood flowing and restore a normal heart rhythm. Chest compressions pump blood to the brain and vital organs, buying time until a defibrillating shock can work. The AED analyzes the heart rhythm and can deliver a shock to restart a normal rhythm when appropriate. Using both as a sequence—start CPR immediately and bring in the AED as soon as it’s available, then follow its prompts—provides the best chance of survival. The CPR maintains perfusion, while the AED delivers the potential life-saving defibrillation, making their combination more effective than either action alone.
