Cardiopulmonary resuscitation simulates human dyspnea. First aid measures are the symbol of human life. When an accidental injury occurs, breathing is difficult or even stops. If you don't give first aid in time, you will soon die. Artificial respiration is a first-aid method to help the wounded breathe with artificial strength and finally restore spontaneous breathing. The patient lies on his back, unbuttons his collar and clothes, and removes secretions, sludge, false teeth, etc. Remove his tongue from his mouth and nose, and if necessary, to prevent the root of his tongue from falling backwards and blocking the respiratory tract. Tilt the patient's head back so that the respiratory tract can be stretched. The rescuer puts his mouth close to the patient's mouth and holds the patient's nostril with the other hand to avoid air leakage. The operator will take a deep breath and blow it evenly into the patient's mouth, so that the patient's chest can blow with it. If the patient's teeth are closed and mouth-to-mouth breathing is impossible, the patient's lips can be closed by mouth-to-mouth breathing. Until the patient's automatic breathing is restored.

Cardiopulmonary resuscitation model Training model for beginners is a method to solve problems in teaching. The biggest advantage of model teaching is that it can turn boring microstructure knowledge into interesting and easy-to-understand pictures. It can broaden students' knowledge horizons and stimulate students' imagination. Cardiopulmonary resuscitation simulating chest compressions is of great significance to the teaching of mechanical and electrical specialty. Students' understanding will be deeper. Cardiopulmonary resuscitation simulator initially trains medical skills, and it is difficult to reach the correct operating standard in a short time. When using real person simulation, after all, real people can't simulate the actual effect of the injured.

Cardiopulmonary resuscitation simulator, matters needing attention in artificial respiration. On-site first aid artificial respiration can adopt mouth-to-mouth artificial respiration or simple breathing bag. You can also use a ventilator with more complicated structure and perfect function to rescue patients with respiratory arrest in the hospital. Therefore, in some accidents, such as electric shock, drowning, cerebrovascular and cardiovascular accidents, once the heart stops breathing, the first rescue measure is to carry out artificial respiration and chest compressions quickly to maintain effective ventilation and blood circulation and ensure oxygen supply to important organs. In addition, there are supine chest pressure artificial respiration, prone back pressure artificial respiration, supine arm-hugging artificial respiration and other methods. Precautions for artificial respiration: keep the patient's respiratory tract unobstructed, unbutton his clothes and prevent overexertion. In case of chest rib fracture or other conditions unsuitable for artificial respiration, other first aid measures should be taken immediately. If both breathing and heartbeat stop, massage should be performed at the same time.
