The adult airway infarction and cardiopulmonary resuscitation (CPR) model is a highly realistic medical teaching device, specifically designed for first aid and nursing training. It aims to help trainees master the identification and management of adult airway obstruction as well as CPR skills. This model realistically reproduces the structure and circulatory characteristics of the adult respiratory system, and can simulate emergency situations such as airway obstruction, apnea, and cardiac arrest, providing trainees with an operating environment close to real clinical practice.

In teaching, trainees can practice skills such as the Heimlich method for handling airway obstruction, external chest compression, artificial respiration, airway management, and the operation of automated external defibrillation (AED) through this model. The model is equipped with an adjustable resistance and feedback system, which can display the depth of compression, frequency and ventilation effect, helping trainees correct their operation movements and ensuring the accuracy and standardization of skill mastery.

In addition, this model can be used for contextualized training and team collaboration drills, enhancing trainees' adaptability and clinical decision-making ability in sudden respiratory or cardiac emergencies. The application of adult airway infarction and cardiopulmonary resuscitation models not only enhances the practical skills of medical staff but also provides a safe and controllable training platform for first aid education, which is of great significance for ensuring the life safety of patients.
