Official title
Real Time Assessment of Pre-oxygenation Utilizing End-tidal Oxygen Measurements Versus Single Breath End-Tidal Oxygen Measurements in Healthy Volunteers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study examines the performance of a nasal cannula end-tidal oxygen (EtO2) measurement as compared to the gold standard of single breath end-tidal oxygen measurements in healthy volunteers. The purpose of this study is to examine the ability of each sensor to predict oxygen levels in real time.
