Heimlich is an American doctor who is engaged in surgery. In clinical work, heimlich was shocked by the cases of suffocation death caused by foreign bodies in the United States every year. In an emergency, doctors often pat the back or put their fingers into their mouths and throats to take out foreign bodies, which may have poor results and even lead to foreign bodies entering the respiratory tract. Therefore, heimlich led the team to invent a new first-aid method through continuous research and repeated animal experiments, using the residual gas in the lungs to form an airflow to rush out foreign bodies. Because this first aid method has saved countless lives, the American Medical Association named it after heimlich.
In addition, the principle of Heimlich's first aid method is to use the soft tissue under the abdominal diaphragm to generate upward pressure, and the lower part of the lung is compressed, so that the residual air in the lung forms an airflow with impact force, which can drive away food blocking the trachea and throat.
Finally, remind parents that the incidence of foreign bodies in children's trachea is very high, so parents should pay attention to it, actively prevent foreign bodies in children's trachea from being stuck, prohibit children from putting toys in their mouths, and don't give children large pieces of food that is difficult to swallow, so as to avoid laughing, talking and running while eating.
