What is the purpose of using an Automated External Defibrillator (AED)?

The purpose of using an Automated External Defibrillator (AED) is to restore a normal heart rhythm during cardiac arrest. When someone experiences sudden cardiac arrest, their heart may be beating erratically or not at all, which prevents it from effectively pumping blood throughout the body. AEDs are designed to analyze the heart's rhythm and, if necessary, deliver an electrical shock known as defibrillation to help reset the heart's electrical system. By restoring a normal rhythm, the AED plays a crucial role in increasing the chances of survival before advanced medical care can be provided.

While monitoring vitals can be an essential aspect of assessing a patient's condition, AEDs primarily focus on addressing life-threatening arrhythmias rather than monitoring. Providing oxygen is a critical aspect of managing respiratory emergencies, but it is not the primary function of an AED. Additionally, while CPR and defibrillation can be complementary in a cardiac arrest situation, the AED does not replace the need for CPR; instead, it enhances the overall response to cardiac emergencies when used in conjunction with effective CPR.
