Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Clinician Perception Score - Frequency of Technical/Clinical Difficulties	Clinician's subjective assessment of the frequency of technical or clinical issues during the the test, rated as units on a visual analog scale from 0 to 100. Lower scores indicate a better outcome.	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)
Other	Clinician Perception Score - Patient Comfort/Tolerance	Clinician's subjective assessment of the patient's comfort and tolerance of therapy during the the test, rated as units on a visual analog scale from 0 to 100. Lower scores indicate a better outcome.	Through study completion, an average of 3 hours
Other	Clinician Perception Score - Ease of Use	Clinician's subjective assessment of the ease of use of therapy during the the test, rated as units on a visual analog scale from 0 to 100. Lower scores indicate a better outcome.	Through study completion, an average of 3 hours
Other	Clinician Perception Score - Monitoring & Support for Therapy	Clinician's subjective assessment of the level of monitoring and support for therapy required during the the test, rated as units on a visual analog scale from 0 to 100. Lower scores indicate a better outcome.	Through study completion, an average of 3 hours
Other	Clinician Perception Score - Expected/Perceived Patient Outcomes	Clinician's subjective assessment of the expected and perceived patient outcomes as a result of therapy following testing, rated as units on a visual analog scale from 0 to 100. Lower scores indicate a better outcome.	Through study completion, an average of 3 hours
Other	Patient Perception Score - Relief of Symptoms	Patient's subjective assessment of relief of their symptoms while on therapy, rated as units on a visual analog scale from 0 to 100. Lower scores indicate a better outcome.	Through study completion, an average of 3 hours
Other	Patient Perception Score - Comfort/Tolerance of Therapy	Patient's subjective assessment of their comfort and tolerance of therapy during the the test, rated as units on a visual analog scale from 0 to 100. Lower scores indicate a better outcome.	Through study completion, an average of 3 hours
Primary	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.	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)
Secondary	Patient Vital Signs - Heart Rate [HR]	Heart Rate (HR) The number of beats per minute.	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)
Secondary	Patient Vital Signs - Respiratory Rate [RR]	Respiratory rate, measured in breaths per minute (brpm)	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)
Secondary	Patient Vital Signs - Blood Pressure [BP]	Blood pressure (systolic) measured in mmHg	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)
Secondary	Patient Vital Signs - Arterial Oxygen Saturation [SpO2]	SpO2 measured as percentage of oxygen saturation (%)	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)
Secondary	Patient Vital Signs - Transcutaneous CO2 [TcPCO2]	TcPCO2 measured as percentage of CO2 (%)	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)
