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.

Autonomic dysfunction is present early in the course of COPD, and is associated with adverse outcomes. We utilized heart rate recovery, a simple and validated index of autonomic balance, to investigate the effects of exercise training on autonomic dysfunction in patients with COPD. ⋯ In subjects with COPD, exercise-based rehabilitation improves heart rate recovery, modestly though, which indicates a degree of attenuated autonomic dysfunction. Exercise and muscular oxidative capacity, as expressed by V(O(2))/t slope, is also improved.
