The aim of the study was to evaluate the adequacy of diagnosis and management of respiratory failure (RF) in COPD. ⋯ Agreement between diagnosis of RF and ABG values was found to be insufficient in about half the cases. Among secondary end points, adherence of the treatment to guidelines and LTOT prescription were, however, found to be good. Data showed significant inaccuracies in the management of RF at our institution.

Oxidative stress has been known for having a key role in pathogenesis of many diseases. The aim of this study was to investigate the oxidative stress and also the relationship between antioxidant system statuses and lung function in patients with COPD and smokers and non-smokers subjects. ⋯ Decreased total antioxidant capacity in plasma of subjects with COPD and smokers suggests an increased oxidative stress in this group. However, no relationship was found between lung function and antioxidant systems status in COPD subjects.
