Ø What Is AED
Cardiac arrest is defined as the sudden stop of heartbeat caused by various reasons, because of which blood cannot be sent to the brain or other vital organs. If a patient is not effectively treated within 4 minutes, irreversible brain damage may lead to brain death in 10 minutes. Each year in China, more than 500,000 people die from cardiac arrest, which becomes the first cause of death, surpassing cancer and stroke. The age of onset is getting younger and younger. It is reported that the survival rate of Chinese patients with cardiac arrest is less than 1%, since most patients have been dead before arriving at the hospital or receiving effective treatment.
Automated External Defibrillator (AED) is a smart portable emergency device that automatically recognizes ventricular fibrillation or pulseless ventricular tachycardia. It can automatically charge and terminate fatal arrhythmias by electric shock, thereby recovering the heartbeat to save lives.

Ø How to Use
Once cardiac and respiratory arrest happens to a person in public, please immediately call 120 and perform cardiopulmonary resuscitation and AED defibrillation, and seek advanced life support and comprehensive post-treatment for the patient.
Four Steps:
Step 1: Turn on the green power switch of the machine, and then there will be text and voice prompts for the next operation;
Step 2: Open the lid and remove the electrode pads. Let the patient lie on his back and paste the electrode piece as required. The “A” electrode piece is attached to the left chest of the patient to cover the apex. The “S” electrode piece is attached to the right scapular region of the patient or the sternal rim of the right clavicle. (The figures on the machine are for reference)
Step 3: Press the yellow analysis button, the instrument will prompt “analysis” of the patient's heart rate to determine whether it is in ventricular fibrillation status or not;
Step 4: If considering the patient in ventricular fibrillation status, the machine will prompt “now in ventricular fibrillation state” and automatic charging will be performed. At this time, the operator should avoid contacting with the patient. When the machine prompts “Charging is completed. Please do defibrillation.”, please press the green defibrillation button and the machine will automatically discharge for electric shock defibrillation.
