Fractionated breath condensate sampling: H2O2 concentrations of the alveolar fraction may be related to asthma control in children

摘要

BackgroundAsthma is a chronic inflammatory disease of the airways but recent studies have shown that alveoli are also subject to pathophysiological changes. This study was undertaken to compare hydrogen peroxide (H2O2) concentrations in different parts of the lung using a new technique of fractioned breath condensate sampling.
