According to the doctor's quick inquiry, AED (automated external defibrillator) is a kind of medical equipment for rescuing patients with cardiac arrest. When using AED for first aid, the positions of electrode pads are indeed interchangeable. This mainly depends on the operating habits of the rescuer or the patient's situation.
Electrode pads are usually designed to be attached to the patient's chest or shoulders in order to accurately detect the electrical activity of the heart. The electrode pads are connected with the main machine of AED through wires, and the electrical signals of the heart are transmitted to AED for analysis. When the position of the electrode sheet needs to be changed, the ambulance personnel can paste it according to the diagram on the electrode sheet. Some AED electrode pads are even designed to be interchangeable, so that rescuers can adjust them according to the actual situation.
