After an AED delivers a shock, what is the next step for rescuers?

After an AED delivers a shock, the next step for rescuers is to resume CPR, starting with chest compressions. This action is critical because the heart may still be in a potentially resuscitatable rhythm, but it is not effectively pumping blood. CPR helps initiate blood circulation and delivers oxygen to vital organs, which is essential for the survival of the patient until advanced medical help can arrive or until the patient regains a stable heart rhythm.

The recommendation to immediately resume CPR following a shock reflects current guidelines aimed at maximizing the potential for recovery. Continuing CPR for two minutes before rechecking the pulse or using the AED again helps maintain blood flow, especially in the absence of a detectable pulse.

This approach also allows the AED to be utilized promptly when needed, ensuring that the patient's chances of survival are optimized by not delaying critical interventions like chest compressions after the shock has been delivered. Maintaining a cycle of CPR and using the AED as indicated are central to effective emergency response in cases of cardiac arrest.
