What action should you take if an AED does not advise shock but the person is unresponsive?

When an automated external defibrillator (AED) does not advise a shock but the person is unresponsive, it is crucial to continue CPR until professional help arrives. This is because the lack of a shock indication does not imply that the situation is not serious; the individual may still be experiencing a life-threatening emergency such as cardiac arrest. CPR is essential in this scenario as it helps maintain blood flow to vital organs, increasing the chances of survival until advanced medical personnel can provide further assistance.

Continuing to perform CPR helps to keep the heart's blood pumping and provides oxygen to the brain and other organs. In cases where the person may still be experiencing a shockable rhythm, starting CPR immediately after the AED's assessment is critical for the victim's chance of recovery. Regular cycles of compressions and rescue breaths can significantly impact the outcome, making it important not to interrupt this lifesaving procedure unnecessarily.
