Randomized Controlled Trial Comparative StudyHome-based pulmonary rehabilitation in very severe COPD: is it safe and useful?
To determine the safety and usefulness of a home-based pulmonary rehabilitation program for patients with very severe chronic obstructive pulmonary disease (COPD) who receive long-term treatment with oxygen. ⋯ A home-based pulmonary rehabilitation program for patients with very severe COPD under long-term oxygen treatment is safe and useful, as it achieves an improvement in exercise tolerance, reduces dyspnea after effort, and improves quality of life without causing any complication arising from the performance of the exercises.

Randomized Controlled Trial Comparative StudyInterval training versus continuous training in patients with chronic obstructive pulmonary disease.
The purpose of this study was to compare the effects of interval training (IT) and continuous steady-pace training (CT) in patients with COPD. ⋯ Compared with CT, IT was well tolerated and produced similar improvements in exercise performance and quality of life.

Randomized Controlled Trial Clinical TrialNoninvasive ventilation with continuous positive airway pressure acutely improves 6-minute walk distance in chronic heart failure.
Noninvasive ventilation with continuous positive airway pressure (CPAP) has been used in patients with chronic heart failure (CHF), although its effect on exercise tolerance in these patients is unknown. The aim of this study was to determine the effects of CPAP on exercise tolerance in outpatients with CHF. ⋯ Noninvasive ventilation with CPAP increased exercise tolerance in patients with stable CHF. Future clinical trials should investigate whether this effect is associated with improved clinical outcome.

Randomized Controlled TrialEfficacy of pursed-lips breathing: a breathing pattern retraining strategy for dyspnea reduction.
Breathing pattern retraining is frequently used for exertional dyspnea relief in adults with moderate to severe chronic obstructive pulmonary disease. However, there is contradictory evidence to support its use. The study objective was to compare 2 programs of prolonging expiratory time (pursed-lips breathing and expiratory muscle training) on dyspnea and functional performance. ⋯ Pursed-lips breathing provided sustained improvement in exertional dyspnea and physical function.
