The adult airway infarction and CPR model is a highly realistic simulation teaching device, specially designed for first aid training and clinical skills training, aiming to enhance trainees' ability to handle airway infarction and cardiopulmonary arrest. This model realistically reproduces the structure of the upper airway in adults, including the oral cavity, throat, larynx and trachea, and can also simulate the breathing obstruction caused by foreign body blockage.

During the training process, trainees can practice airway clearance, the Heimlich maneuver and other techniques for relieving infarction, and at the same time perform cardiopulmonary resuscitation operations such as external chest compressions and artificial respiration. Models are usually equipped with feedback systems that can provide real-time prompts on the depth, frequency of compression and airway patency, enabling learners to adjust their operations promptly and master standardized procedures.

Through repeated practice, trainees can enhance their hand-eye coordination, operational proficiency and clinical adaptability, while avoiding the risks associated with training on real patients. Adult airway infarction and CPR models play a significant role in medical education, nursing training and first aid drills, providing trainees with a safe, controllable and repeatable training environment to help them save lives quickly and effectively in emergencies.
