What should you do immediately after delivering a shock with an AED?

The correct action to take immediately after delivering a shock with an AED is to continue CPR. The reason for this is that once the AED has analyzed the heart rhythm and delivered a shock, it is crucial to keep the blood circulating to vital organs by performing high-quality chest compressions.

Continuing CPR helps to maintain blood flow and oxygenation to the brain and other important organs while the heart attempts to re-establish a normal rhythm. This is especially important given that the person's heart may still be in a dangerous state and may require additional support to recover.

Other actions, such as calling 911 or assessing the patient for responsiveness, are important but should occur at a different stage of the emergency response. Waiting for medical assistance to arrive is also not ideal, as immediate action is necessary to enhance the chances of survival. Quick and ongoing CPR, along with the use of an AED, is critical in such emergency situations.
