What is the immediate next step after administering an AED shock?

After administering an AED shock, the immediate next step is to resume CPR for 3 complete cycles, which typically consists of cycles of 30 chest compressions followed by 2 rescue breaths if trained in CPR. This is crucial because after a shock is delivered, the victim may still be in a state where their heart is not effectively pumping blood, and chest compressions can help to circulate oxygenated blood to vital organs.

Continuing CPR maximizes the chances of restoring a normal heart rhythm and increases the likelihood of survival until further advanced medical assistance can arrive. The focus during this critical period is to maintain blood circulation, as even after a shock, survival hinges greatly on the prompt application of high-quality CPR. The intervals of CPR should be sustained until an additional AED analysis is available or until the emergency responders take over care.
