Recently, a tragedy occurred in Yulin, Guangxi, a 6-year-old boy choked at home while eating peanuts, parents panicked and sent the child to the hospital, community surveillance captured the scene: a woman in red running into the elevator with an unconscious child on her back, in the process of the elevator down, the woman grabbed the child’s feet with both hands, kept shaking, and even carried the child upside down on his shoulders, constantly slapping the child with his hands back, but the child never responded. When the child was taken to the hospital, there was no heartbeat breathing, lips purple, pupils dilated, and died after rescue. According to incomplete statistics, nearly 3,000 children die of asphyxiation every year due to accidents such as swallowing foreign bodies or obstruction of tracheal foreign bodies in China. It is very common for children to be stuck with foreign bodies, and it is often fatal in five or six minutes. Therefore, it is very important to deal with this unexpected situation in a timely and proper manner. It is recommended that if a child gets stuck with a foreign object, the Heimlich maneuver can be used immediately and the child can be treated at a hospital in a timely manner. Who is Heimlich immediately? Why is the Heimlich maneuver so amazing? Heimlich was an American thoracic surgeon who, after repeated studies in the clinic, finally invented the first aid method of using residual gas in the lungs to form an air current to flush out foreign bodies. Over the decades, this method has saved at least 100,000 lives. Who’s Who in the World called Heimlich “the man who saved the most lives in the world”. So what is the principle of the Heimlich maneuver? The Heimlich maneuver: using the impact on the abdomen – the soft tissue under the diaphragm, the sudden impact generates upward pressure, compressing the lower part of both lungs, thus driving the residual air in the lungs to form a stream of air. This airflow with impact and directional long drive in the trachea can then drive out foreign bodies such as hard pieces of food blocking the trachea and larynx, allowing the person to be saved. Having said that, how does the Heimlich maneuver work? The first responder first stands firmly with the front leg bowed and the back leg boarded, then makes the patient sit on his bowed thighs and lets his body lean forward slightly. Then extend both arms from under the patient’s armpits and encircle the patient. Left hand fist, right hand from the front to hold the left wrist, so that the left fist tiger mouth in the patient’s chest below, above the navel in the middle of the upper abdomen, forming a “closed” position, and then suddenly tighten the arms, with the left fist tiger mouth to the patient’s upper abdomen in the upper violent pressure, forcing the upper abdomen sink. As the abdomen sinks, the abdominal cavity moves upward, forcing the diaphragm to rise and squeeze the lungs and bronchi, so that each impact can provide a certain amount of air for the airway, thus flushing the foreign body out of the trachea. Immediately after applying pressure, the arm is relaxed and the procedure is repeated until the foreign body is expelled. The health of a child is related to the harmony of a family, and it is recommended that parents become proficient in the Heimlich maneuver (you can search online and practice more), just like mastering CPR.
