J68: Respiratory conditions due to inhalation of chemicals, gases, fumes and vapours

J68.0: Bronchitis and pneumonitis due to chemicals, gases, fumes and vapours

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.

You have inhaled substances, vapors or smoke. As a result, the mucous membrane of your bronchial tubes was irritated. The mucous membrane of your bronchial tubes has become inflamed and is swollen. It is also possible that your lungs have become inflamed as a result.

Due to an inflammation in the bronchial tubes or lungs, you may have various symptoms. These include shortness of breath, coughing and phlegm. Phlegm is thick mucus that is coughed up. Shortness of breath can get worse when the lungs additionally become inflamed.
