The observational study consists in collecting physiological data (cardiorespiratory and physical activity) and use of the oxygen therapy device in real life during the first months after the initiation of treatment.
For this purpose, two connected medical devices will be provided to each patient during 2 periods of 2 weeks (weeks 6 to 8 then weeks 12 to 14 after the initiation of oxygen therapy). The devices are: 1/ a connected watch that continuously measures vital parameters (heart rate and blood oxygen saturation), and physical activity parameters (no. of steps, distance, duration of effort), and 2/ a Teleox device that remotely monitors patients equipped with an oxygen source (it measures the oxygen flow rate requested by the patient, the duration of use of the oxygen source, and the breathing rate).
Study design: a cohort of 250 patients with COPD newly initiated a long term oxygen therapy will be enrolled in the study and follow-up over 6 months. Data will be collected by lung specialists and home health care provider teams at 2 months, 3.5 months and 6 months post-initiation of oxygen therapy.
