- Primary Outcome Measures
Name Time Method Exhaled Oxygen Concentration Immediately after 3 minutes of oxygen supplementation Subjects will blow into an oxygen sensor after each method (arm). The primary outcome will be a non-inferiority test between bag valve mask and non-rebreather at 60 L/min. The remaining tests will be completed for comparison, but not part of formal statistical testing.
