Food ingested into the trachea can usually heal itself, but if it enters the trachea at a deeper level and is a large foreign body, it can be difficult to heal itself. If a small foreign body enters the trachea at a shallow depth, it is usually not a big problem, and these patients can usually heal themselves by coughing the foreign body out of the body. But if it is a relatively large foreign body, and into the deepest layer of the trachea, it is difficult to cough out, this situation needs to go to the hospital as soon as possible to check, to understand the specific location of the foreign body and the size of the foreign body, in the case of being able to take out, you can cooperate with the doctor to carry out microscopic removal of objects; if the foreign body can not be taken out, it is necessary to do as soon as possible to make a tracheotomy. After the food enters the trachea, it should be observed, and if you feel breathless with the risk of choking, you should consult a doctor immediately so as not to delay the rescue treatment.
