In the field of emergency care, defibrillators are known as "life-saving devices", which can help restore a patient's heartbeat at a critical moment and save lives. However, in practice, the use of defibrillators requires an extremely high level of expertise and experience. In order to train more qualified first responders, analog defibrillators came into being. But is the existence of an analog defibrillator really necessary?

First, we must recognize the unique value of analog defibrillators in first aid training. It provides a safe, risk-free practice environment for participants to familiarize themselves with the defibrillator procedure, the fundamentals of defibrillation, and the stresses and challenges of using a defibrillator in an emergency without an actual patient. This kind of simulation exercise is essential to improve the self-confidence and coping skills of the participants.

Secondly, analog defibrillators can also help students better grasp the timing and techniques of defibrillation. In practice, it is crucial to determine when to use a defibrillator, how to choose the right energy level, and how to perform effective follow-up treatment after defibrillation. Through repeated practice with a simulated defibrillator, students can experiment and adjust without actual risk until they find the operation that works best for them.

In addition, the simulated defibrillator helps to develop the participants' teamwork and communication skills. In a real first aid scenario, medical staff need to work closely together to respond to an emergency. Through the practice of simulating a defibrillator, students can learn how to communicate effectively in a team and how to coordinate their actions to provide better emergency care.

To sum up, the existence of a simulated defibrillator is very necessary. It not only provides a safe and effective practice platform for first aid training, but also helps students to better master defibrillation skills, improve self-confidence and coping ability. At the same time, through the practice of simulated defibrillators, students can also develop teamwork and communication skills, laying a solid foundation for future practical work. Therefore, we should pay full attention to the role of simulated defibrillators in first aid training, actively promote and use this advanced training tool, and make contributions to training more qualified first aid personnel.
