Evaluation of Oxygen Delivery Through Nasal Cannula in Volunteers

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 outcomes

  1. End-tidal Oxygen

    Time frame: Continuously throughout 30 minute volunteer study

    Did the novel system increase end-tidal oxygen?

  2. Patient Comfort

    Time frame: Every 2 minutes up to 30 minutes

    Did the patients feel it was more comfortable for a given end-tidal oxygen level?

  3. End-tidal Carbon Dioxide

    Time frame: Continuously throughout 30 minute volunteer study

    Was end-tidal carbon dioxide measured more accurately using the novel system?

  4. Respiratory Rate

    Time frame: Continuously throughout 30 minute volunteer study

    Compared respiratory rate against capnometry.

  5. Oxygen Saturation

    Time frame: Continuously throughout 30 minute volunteer study

    Did the novel system increase oxygen saturation?
