The CPR (cardiopulmonary resuscitation) model plays a vital role in the first aid training of adults with airway infarction, not only as a bridge between theory and practice, but also as a key tool for improving first aid skills and ensuring patient safety.

First, it provides students with a safe and risk-free practice environment. In a real first aid scenario, any misoperation can cause irreversible harm to the patient. The model completely eliminates this risk, so that students can boldly try and practice without pressure, and gradually master the correct first aid skills. This safe learning environment is essential for developing self-confidence and coping skills.

Second, it can highly simulate real airway infarction and CPR operation scenarios. By simulating human anatomy and physiological responses, the model allows students to feel resistance and feedback similar to real situations during operation. This immersive experience helps students better understand the principles and applications of first aid skills, improving their judgment and execution in emergency situations.

Finally, the CPR model also plays an important role in popularizing first aid knowledge and passing on skills. Through model demonstration and explanation, teachers can clearly show the steps and key points of first aid operation to students, so that complex first aid skills become easy to understand and master. At the same time, the model can also be used as a teaching tool to publicize and educate first-aid knowledge in medical institutions, communities, schools and other places to improve the public's first-aid awareness and self-rescue and mutual rescue ability.

To sum up, adult airway infarction and CPR model play an irreplaceable role in first aid training. It is not only an important tool for students to master first aid skills, but also the key to ensure patient safety and improve the level of first aid.
