Adult airway infarction and CPR models play a vital role in medical training and first aid training, and one of their main goals is to simulate real first aid scenarios as fully as possible. By analyzing the functional features and design principles of such models in depth, we can clearly see how they achieve this goal.

First, the adult airway infarction model can accurately simulate the emergency situation of airway obstruction by foreign objects. This model usually has a realistic airway structure and simulated infarcts, so that the medical staff can master the correct operation skills in practice. The model can provide a highly realistic training environment by simulating typical behaviors such as the hand involuntarily pointing to the neck of the obstructed person and the painful expression on the face.

Secondly, the CPR model can simulate the physiological response of the human body during cardiac arrest, including cardiac arrest, respiratory arrest, etc. This model not only supports standard CPR procedures, such as artificial respiration and compressions, but also simulates chest expansion during airway passage, as well as suffocation and obstruction of the airway by foreign objects. By simulating these real-world scenarios, healthcare professionals can better understand and master CPR skills during training.

In terms of simulating real emergency scenarios, the adult airway infarction and CPR model also has the following key features:

Real-time feedback: These models are often equipped with a real-time feedback system that monitors the medical staff's operation and gives corresponding feedback. This kind of feedback can not only help the medical staff find their own mistakes and shortcomings in time, but also guide them to make targeted improvements and improvements.

Multiple modes of operation: The model supports a variety of ventilation and chest compression techniques, allowing healthcare professionals to experiment with different methods of operation during training and find the one that works best for them.

Highly simulated: The anatomical structure and physiological characteristics of the model are carefully designed to ensure that it is highly simulated. This simulation enables medical staff to feel similar touch and feedback to real patients during training, thus improving the training effect.

In summary, the adult airway infarction and CPR model can fully simulate the real first aid scene, and provide a realistic training environment for medical personnel. By training and learning in this environment, medical staff can better master first aid skills and improve their ability to respond to emergencies.
