What should rescuers do if the AED prompts "No shock advised"?

When an Automated External Defibrillator (AED) displays the message "No shock advised," it indicates that the device has detected a heart rhythm that does not require defibrillation, such as a pulseless electrical activity or asystole. In this situation, it is critical for rescuers to continue performing cardiopulmonary resuscitation (CPR) immediately.

Continuing CPR is essential because it helps maintain blood circulation and oxygenation to vital organs until emergency medical personnel arrive or the victim exhibits signs of life, such as natural breathing or responsiveness. The ongoing compressions also enhance the chances of a successful outcome by keeping the blood flowing through the body, which may result in a change in the victim's heart rhythm that could subsequently lead to a shock being advised by the AED.

Stopping CPR or solely awaiting further instructions would significantly reduce the victim's chances of survival. Other actions, such as rechecking the pulse or attempting manual compressions alone, do not provide the continuous support needed during this critical phase of resuscitation. Therefore, continuing CPR is the appropriate and lifesaving action in response to a "No shock advised" prompt.
