Foreign bodies are frequently reaching into the pharynx, the larynx or the trachea, especially in children. This cause symptoms in two ways: by obstructing the air passage that causes difficulty in breathing; they may be drawn further down later on, entering the bronchi causing symptoms of irritation, such as a cough, bloody or mucous expectoration. If the foreign body has lodged into the pharynx, this may be lodged by inserting the finger; if the obstruction is in the larynx or the trachea, a tracheotomy is immediately necessary.
A tracheotomy is a surgery that is performed by inserting a medical tube, also known as breathing or endotracheal tube that can open up someone's airways
