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.

Condition

  • COPD

Arm Groups

ArmDescriptionAssigned 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
  • Device: Nasal High Flow Cannula
    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
  • Device: Nasal Low Flow Cannula
    Low flow nasal cannula is a device that provides low flow gases. In-person. Depending on participant's availability, up to 6 times
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
  • Device: Nasal High Flow Cannula
    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
  • Device: Nasal Low Flow Cannula
    Low flow nasal cannula is a device that provides low flow gases. In-person. Depending on participant's availability, up to 6 times
