Study Summary
The intent of this study is to determine the difference in pharyngeal oxygen concentration in patients who have a natural airway (not intubated) using commonly available oxygen delivery systems. The investigators will test the hypothesis that oxygen concentration during the period of inspiration (FiO2) in the pharynx is dependent on oxygen delivery system design, even at high flow (15 liters/minute) oxygen delivery. Specific measurements include oxygen concentration at subjects' lips and pharynx when breathing 100% oxygen and room air via a simple mask, non-rebreather mask, OxyMaskTM, and anesthesia mask with headstrap and Jacson Rees circuit. A mean difference of 10% pharyngeal FiO2 between any of the masks will be considered clinically important. The expected standard deviation of the within-subject FiO2 is 3.5%. With a significance criterion of 0.05, 10 subjects would provide more than 90% power to detect a mean difference of 10%.
Primary Outcome
After placement of each mask and starting oxygen high flow, the subject will breathe normally for 90 seconds and then FiO2 will be measured over the next 30 seconds. At the end of each trial period, each subject will be asked to take a single vital capacity breath (starting with maximum exhalation and followed by maximum inhalation). Between testing of each mask, there will be a 5 minute period of breathing room air as a washout period to confirm stability of hemodynamic status (measurement of b
