The simulated defibrillator is a commonly used device in medical teaching and first aid training, mainly used to help trainees master the operation process of electrical defibrillation during cardiac arrest. Its core function lies in providing a safe and controllable learning environment, allowing trainees to become familiar with the structure, operation steps and precautions of the defibrillator under risk-free conditions.

Simulated defibrillators usually have the function of simulating various arrhythmias, such as ventricular fibrillation, ventricular flutter and pulseless ventricular tachycardia, etc. Trainees can identify electrocardiograms according to the prompts, determine whether defibrillation is needed, and complete energy selection, electrode plate placement and shock operation. Some high-end models can also interact with simulation manikins to provide real-time feedback on heart rhythm changes after defibrillation, enhancing the authenticity of clinical scenarios.

Through repeated training, trainees can enhance the speed and accuracy of heart rhythm recognition and emergency response, and reduce errors in clinical practice. The simulated defibrillator is not only suitable for professional training of medical staff, but also often used in public first aid popularization education. It is of great significance for improving the overall first aid level and ensuring the survival rate of patients with cardiac arrest.
