Brief summary
The purpose of this study is analyzed the impact of oxygen adjusted during exercise in COPD patients without conventional for LTOT but with exercise desaturation.
Detailed description
Oxygen will be administered through nasal cannulae. Patients will be provided with a tank of liquid oxygen and a rechargeable portable device. The 6 minuts walking test will be used to adjusted oxygen flow in the GFA group (to achieve a mean SpO2 ≥ 90%). In the control group (GC), a 3L/min oxygen flow will be administer. Oxygen is used when the patient perform physical activity. The treatment period for each patient is 6 months (3 months in the GC grup, 3 months in the GFA one).
Interventions
Oxygen administered after adjustment during a waking test or at 3L/min
