Infants and young children have not erupted or erupted incompletely, their chewing function is not mature, their swallowing function is not perfect, and their tracheal protective reflex is not sound. When a foreign body falls into the trachea, the most prominent symptom is a violent irritating choking cough, because the trachea or bronchus is partially or completely blocked by foreign bodies, there is shortness of breath, but also because one side of the bronchial obstruction, while the other side inhaled more air, the formation of emphysema, larger or small angular foreign bodies (such as dates) can block the large trachea, a short period of time can occur suffocating death.
