Physiologic Effects of Nasal High Flow on Exercise Tolerance in COPD
Purpose
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.

Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Experimental Nasal High Flow Cannula |
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 |
|
|
Active Comparator Nasal Low Flow Cannula |
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 |
