Randomized Controlled TrialPursed lip breathing improves exercise tolerance in COPD: a randomized crossover study.
Although pursed-lip breathing (PLB) has been advocated to reduce respiratory rate and improve oxygen saturation in patients with chronic obstructive pulmonary disease (COPD) at rest, the evidence of its effects on dynamic hyperinflation (DH) and exercise tolerance is scarce. ⋯ This study points to a possible application of PLB in a selected group of COPD patients aiming at improving the exercise tolerance. PEF measurements can help to indicate PLB for COPD patients.
