This study aims to assess whether to describe the effects of the administration of nasal high flow (NHF) at 70 liters per minute (L/min) in a 6-Minute Walk Test (6-MWT) among Chronic Obstructive Pulmonary Disease (COPD) patients and to characterize the association between self-reported dyspnea with and without NHF at 70 L/min following a 6-MWT.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Nasal High Flow Cannula | Experimental | Nasal High Flow cannula at 70 liters per minute for 30 minutes. Given that this is a cross-over study, participants on this arm will be then crossed over to Nasal Low Flow Cannula at less than or equal to 4 liters per minute with supplemental oxygen for 30 minutes |
|
| Nasal Low Flow Cannula | Active Comparator | Low Flow Nasal Cannula at less than or equal to 4 liters per minute with supplemental oxygen at patient's baseline for 30 minutes. Given that this is a cross-over study, participants on this arm will be then crossed over to High Flow Cannula at 70 liters per minute for 30 minutes |

| Nasal High Flow Cannula | Device | High flow nasal cannula is a device that provides heated and humidified high flow gases. In-person. Depending on participant's availability, up to 6 times |
| Measure | Description | Time Frame |
|---|---|---|
| 6-minute walk test | The object of the test is to walk as far as possible for six minutes. The subject will walk at a normal pace around a marked course for six minutes. The distance walked in meters over 6 minutes will be measured. | 30 minutes |
| Measure | Description | Time Frame |
|---|---|---|
| Breathing measured by the Borg dyspnea scale | This is a patient self-reported scale to rate the difficulty of breathing. The scale ranges from 0 to 10, where "0" indicated no difficulty breathing, and "10" indicates a maximal breathing difficulty. | 30 minutes |
