[1] on their paper which was published in a recent issue of the European Respiratory Journal. The authors observed that persistent exhaled nitric oxide fraction (FeNO) values ≥20 ppb in clinically stable chronic obstructive pulmonary disease (COPD) outpatients are associated with a significantly higher risk of acute exacerbations of COPD (AECOPD). This kind of approach would certainly have significant consequences for the follow-up of COPD patients.HypAir FeNO is an electrochemical sensor; there is no chemiluminescence NO device http://ow.ly/tmvX30irOO7 ER -
