Evaluation of Oxygen Delivery Through Nasal Cannula in Volunteers

Not Applicable

Completed

• Conditions: Patient Monitoring; Oxygen Delivery; Patient Comfort

• Registration Number: NCT02886312
• Lead Sponsor: University of Utah

Brief Summary

This study will evaluate patient comfort and oxygen delivery efficiency when providing supplemental oxygen through a nasal cannula to volunteers using an instrumented oxygen delivery system. The goals of the study are to evaluate different oxygen flow rates and oxygen delivery modes. In addition, the investigators will investigate if the system can detect apnea (cessation of breathing) and removal of the nasal cannula. The investigators will also investigate how well high flow oxygen delivered only during inspiration is tolerated and how much the end-tidal oxygen increases after two minutes of high oxygen flow delivered only during the inhalation phase of the breath.

Primary Outcome Measures

Name	Time	Method
End-tidal Oxygen	Continuously throughout 30 minute volunteer study	Did the novel system increase end-tidal oxygen?
Patient Comfort	Every 2 minutes up to 30 minutes	Did the patients feel it was more comfortable for a given end-tidal oxygen level?
End-tidal Carbon Dioxide	Continuously throughout 30 minute volunteer study	Was end-tidal carbon dioxide measured more accurately using the novel system?
Respiratory Rate	Continuously throughout 30 minute volunteer study	Compared respiratory rate against capnometry.
Oxygen Saturation	Continuously throughout 30 minute volunteer study	Did the novel system increase oxygen saturation?
