Study Arms:
- Conventional HVNI First, Then New HVNI Second (Randomized) (Type: EXPERIMENTAL): The purpose of this intervention is to evaluate the efficacy of the conventional HVNI device design (Precision Flow) to provide targeted relief of dyspnea. The purpose of this intervention is to evaluate the efficacy of a new HVNI device design (V2.0) to provide targeted relief of dyspnea.
- New HVNI First, Then Conventional HVNI Second (Randomized) (Type: EXPERIMENTAL): The purpose of this intervention is to evaluate the efficacy of the conventional HVNI device design (Precision Flow) to provide targeted relief of dyspnea. The purpose of this intervention is to evaluate the efficacy of a new HVNI device design (V2.0) to provide targeted relief of dyspnea.

Based on this trial design, predict the completion outcome and termination type (if applicable).
