The Advanced Adult Airway infarction and CPR model is a highly realistic simulation device for first aid skills training, specifically designed for the management of adult airway infarction and cardiopulmonary resuscitation (CPR) operations.

Before operation, it is necessary to check whether the oral cavity, airway and thorax of the model are intact, and prepare the artificial respirator, mouth-to-mouth breathing protective cover and disinfection supplies needed for training. Trainees need to first assess the consciousness and breathing state of the "patient", simulate the operation of relieving obstruction such as Heimlich maneuver or back tapping when airway obstruction is detected, and ensure the airway is unobstructed

Subsequently, cardiopulmonary resuscitation training was carried out, including alternating chest compressions and artificial respiration, maintaining the depth and frequency of compressions in line with adult first aid standards. The model is equipped with an electronic feedback system that can display the compression depth, frequency and ventilation effect in real time, helping trainees correct operational deviations. During the operation, one should strictly follow the training norms to ensure correct techniques and smooth movements.

After the training is completed, the mouth and chest area should be cleaned and necessary maintenance should be carried out to extend the service life of the model. Through systematic training in advanced adult airway infarction and CPR models, trainees can master the first aid operation procedures proficiently, improve their clinical emergency handling capabilities and the success rate of actual rescue.
