J68.2: Upper respiratory inflammation due to chemicals, gases, fumes and vapours, not elsewhere classified

The respiratory tract guides air into the lungs. The upper respiratory tract begins in the mouth and nose. The sinuses are also part of the upper respiratory tract. The sinuses are connected to the nose via a small opening. The throat is located behind the mouth and nose. The throat connects the mouth and nose with the windpipe (trachea) and gullet (oesophagus). The larynx is located at the junction between the throat and windpipe. The larynx can be seen from the front as a bulge in the neck. The upper respiratory tract ends at the larynx. The airways are covered with mucous membrane.

You have inhaled substances, vapors or smoke. As a result, the mucous membrane in your upper respiratory tract was irritated. The mucous membrane has become inflamed as a result. Typical symptoms can be hoarseness, coughing and a runny nose.
