What is the guideline for using an automated external defibrillator (AED)?

Using an automated external defibrillator (AED) is critical for increasing the chances of survival in a patient experiencing sudden cardiac arrest. The primary guideline is to use the AED on any unresponsive patient who is not breathing. This aligns with the purpose of the AED, which is to detect and treat life-threatening arrhythmias such as ventricular fibrillation or pulseless ventricular tachycardia, which typically occur in unresponsive patients.

When a patient is unresponsive and not breathing, it indicates a medical emergency where immediate intervention is necessary. In such scenarios, the AED can analyze the heart's rhythm and deliver a shock if indicated, which can potentially restore a normal heart rhythm and allow the patient to regain consciousness and breathing.

It is essential to note that using an AED on a conscious patient is inappropriate, as they are not in immediate danger of cardiac arrest, and the device is designed for situations where emergency intervention is critical. Administering CPR before using the AED is good practice, but the guidelines state that an AED should be used as soon as possible on an unresponsive patient, regardless of whether CPR has been initiated. It is also beneficial to have assistance when using the device to ensure that emergency protocols are followed, but the presence of a helper
