What should you do if an AED advises a shock?

When an automated external defibrillator (AED) advises a shock, it indicates that the device has detected a life-threatening arrhythmia that requires defibrillation to restore a normal heart rhythm. Pressing the shock button without hesitation is the appropriate response, as it is critical to deliver the shock immediately to maximize the chances of survival. The AED is designed to evaluate the heart rhythm and will not advise a shock unless it is necessary; therefore, trusting its guidance is essential in an emergency situation.

Timing is crucial in cardiac arrest scenarios, and delays in delivering a shock can significantly reduce the likelihood of a successful outcome. Immediate action can make the difference between life and death, as every moment counts when treating someone who is unresponsive and not breathing normally. The AED will typically provide clear instructions, but if it indicates a shock is needed, following through promptly is vital.
