Choking

Introduction Cough and numbness and cough. Foreign matter (irritating gas or water, food, etc.) enters the trachea and causes a cough and suddenly spurts out. The throat is rich in nerve distribution. When it is stimulated by foreign matter that is accidentally inserted by drowning, it produces a defensive cough, forcing foreign matter to escape and protecting the lower respiratory tract. When people eat and swallow, they hate to cover their throats. At this time, if you just want to talk, people will inhale, and the food is in the throat, it is easy to enter the trachea with the air, causing severe cough, children coughing or itching throat is more dangerous than adults.
