After delivering a shock from the AED, what is the immediate next step?

After delivering a shock from the Automated External Defibrillator (AED), the immediate next step is to resume CPR immediately. This ensures that effective chest compressions are restarted as soon as possible. The rationale behind this is that following a shock, there is often a brief period where the heart may be able to revert to a normal rhythm. However, there is still a critical need for circulation to maintain blood flow to vital organs, including the brain.

Performing CPR helps to keep oxygenated blood circulating until the heart can stabilize and either regain its normal rhythm or additional interventions can be applied. Time is a crucial factor in cardiac arrest situations; therefore, minimizing the delays in CPR after defibrillation is vital for the victim's chances of survival.

In contrast, options that involve checking the AED for malfunctions or waiting for a set period before continuing do not prioritize the immediate need for cardiovascular support that CPR provides after the shock. Additionally, while reassessing the victim's condition is important, it should be conducted during the CPR cycle rather than interrupting the flow immediately after defibrillation.
