Choking is an irritating cough that occurs when milk accidentally enters the airway during or after a baby eats milk, followed by spitting up a large amount of milk, sometimes with milk coming out of the nasal cavity. The main difference between pneumonia choking and ordinary choking is whether or not symptoms of pneumonia occur when choking, such as coughing, coughing up sputum and fever. After normal choking is relieved, the baby is in good spirits and looks rosy, and it does not affect the appetite. In contrast, choking caused by pneumonia will be accompanied by violent cough, fever, pale face, poor mental state, breathing difficulties and other symptoms, you can also hear wet rales or croup in the lungs, if the above symptoms appear, it is recommended to go to the hospital for relevant examination and timely treatment. Normally, when choking occurs, the baby should immediately stop feeding, quickly place the baby lying flat, face to the side, and use tissue to clean up the milk in the baby’s mouth and nose cavity to avoid secondary choking. Then gently pat the baby’s back with your hand to see if he or she can breathe normally and smoothly. If you find that the baby is not breathing or gradually turning dark and obviously uncomfortable, it means that the spit-up may have entered the trachea. If the symptoms are not relieved, it is recommended to seek emergency medical attention promptly.
