The objective of this study is to evaluate the ability of a new HVNI device to improve ventilation, dyspnea, and related physiological responses relative to the conventional Precision Flow device design, with which there are published clinical outcomes data. It is hypothesized that the new HVNI device design (V2.0) will be comparable at relieving patient dyspnea when compared to the conventional HVNI device design (Precision Flow).
This study will evaluate the ability of a new High Velocity Nasal Insufflation [HVNI] device design to effect ventilation and related physiological responses relative to the current HVNI device design.
