Abstract

The effects of repeated short-term hypoxia on exercise tolerance in patients at risk for, or with mild COPD were investigated. Eighteen patients (10 males, 8 females; 33-72 years) were randomly assigned in a double-blind fashion to receive 15 sessions of intermittent hypoxia (FiO 2: 0.15-0.12) or normoxia within 3 weeks. Three weeks of intermittent hypoxia increased total haemoglobin mass (+4% vs. 0%, p <0.05), total exercise time (+9.7% vs. 0%, p <0.05) and the exercise time to the anaerobic threshold (+13% vs. -7.8%, p <0.05) compared to controls. Changes in the total exercise time were positively related to the changes in total haemoglobin mass (r = 0.59, p <0.05) and changes in the time to the anaerobic threshold were positively related to the changes in the lung diffusion capacity for carbon monoxide (r = 0.48, p <0.05). Intermittent hypoxia treatment may be a valuable addition to therapy designed to improve exercise tolerance in patients at risk for, or with mild COPD.
