Randomized Controlled Trial Multicenter Study
Helium-hyperoxia: a novel intervention to improve the benefits of pulmonary rehabilitation for patients with COPD.
Helium-hyperoxia (HH) reduces dyspnea and increases exercise tolerance in patients with COPD. We investigated whether breathing HH would allow patients to perform a greater intensity of exercise and improve the benefits of a pulmonary rehabilitation program. ⋯ Breathing HH during pulmonary rehabilitation increases the intensity and duration of exercise training that can be performed and results in greater improvements in CLT for patients with COPD.
