Clinical value of nitric oxide parameters in children with bronchial asthma

Abstract

Exhaled nitric oxide （eNO）， as a marker of eosinophilic inflammation in the airway， has been widely utilized in the diagnosis and treatment of asthma. The fractional concentration of exhaled NO （FeNO） mainly reflects the degree of airway inflammation. By establishing a pulmonary dynamic model for extended analysis， nitric oxide parameters can be obtained， which contribute to deepen the understanding of the degree of airway inflammation. In this article， recent studies were reviewed to summarize the clinical value of nitric oxide parameters in asthma， aiming to supplement a novel dimension for the evaluation and management of asthma.
