Chronic obstructive pulmonary disease (COPD) can lead to respiratory failure, but current pharmacological treatments focus on symptom relief or slowing disease progression. Here, the effectiveness of an alternative therapy combining deep-breathing exercises and oxygen inhalation therapy was assessed in mild-to-moderate COPD patients. Forty-two male mild-to-moderate COPD patients were randomly divided into a deep-breathing training group, an oxygen inhalation group, and a combination group (n=14 in each). In the deep-breathing training group, the patients were treated only by the deep-breathing exercise; in the oxygen inhalation group, the patients were treated only by oxygen inhalation; in the combination group, the patients were treated by combining the deep-breathing exercises with oxygen inhalation. Before treatment, there were no statistical differences in the general characteristics or lung function indexes between the three groups of patients (P > 0.05). However, after treatment, patients in the combination group had significantly better lung function indexes than they did before treatment, and their improvement was also superior to that of patients from the deep-breathing training group and the oxygen inhalation group (P < 0.01 and P < 0.05, respectively). Thus, a treatment method combining deep-breathing exercise with oxygen inhalation offers more significant lung function improvement in COPD patients than either the deep-breathing exercise or oxygen inhalation alone. This approach should be further explored for use in the clinic.
