Asthma: 296 The Relationship of Fractional Exhaled Nitric Oxide (FeNO) and Acute Exacerbation of Childhood Asthma

摘要

BackgroundAsthma is a chronic inflammatory disorder in the airways. Measurement of FeNO (fractional exhaled nitric oxide) is a non-invasive tool for measuring airway inflammation. The aim of this study was to investigate the relationship of FeNO and acute asthmatic exacerbation in children and to decide whether measurement of FeNO could predict acute exacerbation of asthma.
