Most food choking into the trachea can be self-healing, choking into the trachea is actually a foreign body in the airway to cause strong irritation of the airway, the human body has the ability to protect the airway, the ability to react normally will produce a violent choking cough, the food into the trachea through the increase in pressure in the chest cavity, through the airflow to remove the food will produce a violent cough. If you are an elderly person, a child or a patient with airway disease, the ability to clear the airway decreases and the function decreases, so the food choked into the trachea will not be easily coughed out and may slide down the airway into the deeper part of the fine bronchi, so you can do a deep breathing action and cough as hard as you can to see if you can cough out the food by increasing the pressure in the chest cavity through your own regulation. If this does not work and you still have a foreign body sensation, you should go to the respiratory department of the hospital for a bronchoscopy to remove the foreign body and remove the food from the trachea through the bronchoscope.
