T17.4: Foreign body in trachea

You have one or more foreign bodies in your trachea.

The air is breathed in through the mouth or nose. From there the air goes into the trachea via the larynx. At the end of the windpipe are two bronchial tubes (or bronchi) branching away from it. The bronchial tubes run into the lungs. What is more, the bronchial tubes divide into even smaller branches. The larynx, the trachea, the bronchia and the lungs are part of the lower airways.

Different types of foreign bodies can get into the trachea. A foreign body may be a mucous plug, for example. Foreign bodies may also be objects, however. If vomit gets into the trachea, this can also be referred to as a foreign body.

If there are foreign bodies in the trachea, there can be various symptoms. For example, the foreign body may make breathing more difficult. Your body may then not get enough oxygen. You may also have a sudden need to cough. A whistling or rattling sound may also be heard when breathing. If foreign bodies remain in the trachea for a long time, inflammation can result there.
