Applications of AEDs in Modern Medicine

An automated external defibrillator (AED) is a portable emergency medical device in modern medicine that automatically identifies abnormal heart rhythms and delivers an electric shock.

Core Functions and Medical Value:

The Golden Four Minutes: After cardiac arrest, irreversible brain damage occurs within four minutes, with survival rates decreasing by 7%-10% for every minute of delay. Early use of an AED in conjunction with cardiopulmonary resuscitation (CPR) can significantly improve survival rates.

Automatic Heart Rhythm Recognition: AEDs automatically analyze the patient's electrocardiogram (ECG) to accurately determine whether it is ventricular fibrillation (VF) or ventricular tachycardia (VT), eliminating concerns about misjudgment even for non-professionals.

Modern Application Scenarios:

Widely deployed in public places:Widely deployed in densely populated areas such as airports, subway stations, shopping malls, schools, and sports fields, breaking the limitations of traditional pre-hospital emergency care that heavily relies on professional medical personnel.

Accessibility and Intelligence: Extremely simple to operate, with clear voice and visual instructions throughout the entire process after activation, guiding ordinary citizens through the entire process of activation, electrode placement, and shock delivery.
