Application of exhaled nitric oxide detection in the diagnosis, treatment and management of chronic airway diseases: current status and prospects

Abstract

Airway inflammation is the most important pathological basis of chronic airway diseases. The detection and evaluation of airway inflammation is helpful for the diagnosis, treatment and management of airway diseases. Exhaled nitric oxide is the most widely used noninvasive airway inflammation detection technique in recent years, which provides a simple and quick reference for the diagnosis and management of chronic airway diseases, but there are still some controversies and deficiencies. This paper briefly expounds the biological significance of exhaled nitric oxide and detecting technique, summarizes the clinical application and the deficiencies of exhaled nitric oxide detection. In the future, with the further researchers on technology and the accumulation of application experiences, the detection technology of exhaled nitric oxide will play a more significant role in the accurate management of chronic airway diseases.
