This study will evaluate the ability of High Velocity Nasal Insufflation \[HVNI\] next generation nasal cannula designs to effect ventilation and related physiological responses relative to the conventional legacy cannula design.
The objective of this study is to evaluate the ability of HVNI next generation nasal cannula designs to effect ventilation and related physiological responses relative to the current cannula design, with which there are published clinical outcomes data. It is hypothesized that next generation nasal cannula designs (Prosoft and Unicorn) will be comparable at relieving patient dyspnea while on HVNI, when compared to the conventional (Legacy) cannula.

Patient Vital Signs -- Rated Perceived Dyspnea (RPD)
Patient's subjective assessment of their dyspnea, rated as a modified Borg score on a scale from 0 to 10. Higher scores indicate a worse outcome.
Time frame: This was collected at the end of each phase, for a total of three phases over the course of the study (2 hours 15 min)
Patient Vital Signs - Heart Rate [HR]
Heart Rate (HR) The number of beats per minute.
Time frame: This was collected at the end of each phase, for a total of three phases over the course of the study (2 hours 15 min)
Patient Vital Signs - Respiratory Rate [RR]
Respiratory rate, measured in breaths per minute (brpm)
Time frame: This was collected at the end of each phase, for a total of three phases over the course of the study (2 hours 15 min)
Patient Vital Signs - Blood Pressure [BP]
Blood pressure (systolic) measured in mmHg
Time frame: This was collected at the end of each phase, for a total of three phases over the course of the study (2 hours 15 min)
Patient Vital Signs - Arterial Oxygen Saturation [SpO2]
SpO2 measured as percentage of oxygen saturation (%)
Time frame: This was collected at the end of each phase, for a total of three phases over the course of the study (2 hours 15 min)
Patient Vital Signs - Transcutaneous CO2 [TcPCO2]
TcPCO2 measured as percentage of CO2 (%)
Time frame: This was collected at the end of each phase, for a total of three phases over the course of the study (2 hours 15 min)
