We will select patients who meet the following criteria:
A) patients having two 6WT early in their program B) who desaturate (SpO2 \<90% for 3 consecutive min) during the first 6WT and who will have been properly corrected with a supply of oxygen during the second walk test.
The analyzed parameters will be distance and dyspnea during the tests

You may be eligible if
Obstructive airflow limitation defined by FEV1/CVF \< 70% and FEV1 \< 80 %

Patients exhibited during the first test, an exercise-induced desaturation, defined by SaO2 \< 90% for 3 consecutive minutes during the 6-minute walking test in the air condition for non-LTOT or with the flow normally recommended during exercise for LTOT patients (i.e., flow rate of rest + 1L/min)
Patients with no desaturation during the test with oxygen supply
