What should be done immediately after delivering a shock from the AED?

After delivering a shock from the AED, the immediate action is to resume CPR without delay. This is crucial because the purpose of the shock is to help restore a normal heart rhythm, but it does not guarantee that the heart will start beating effectively on its own. Resuming CPR provides essential blood flow to vital organs, particularly the brain and heart, which drastically increases the chances of survival.

Continuing with CPR after defibrillation maintains circulation and keeps oxygenated blood flowing to critical areas until advanced medical help arrives or the heart stabilizes. Timing is critical during these life-threatening situations, and minimizing any interruptions in chest compressions is essential for improving outcomes. Therefore, resuming CPR promptly ensures that the patient remains maximally supported while waiting for further medical intervention or for the AED to analyze the heart's rhythm again if needed.

Other options suggest varying approaches, but they do not prioritize immediate resumption of CPR, which is key to providing effective and continuous care.
