Oxygen Delivery, Patient Comfort, Patient Monitoring
Conditions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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? |
