Brief summary

The purpose of this study is to investigate the effect of using the McMurray Enhanced Airway (MEA) which is a flexible extended-length distal pharyngeal airway on improving oxygen delivery compared to standard nasal cannula.

Interventions

Participants in this group will use the nasal cannula to deliver oxygen as per standard of care one time during the in-person visit.

The MEA is non-sterile. It can be used in inpatient or outpatient surgery, in hospital or clinic settings, or in an emergency setting. The MEA has five parts: an optional 15 mm connector, flange (color-coded for size), elongated cushioned bite block, flexible cannula, and distal tip, and a channel to allow for passage of air and a suction catheter. The MEA is designed to open and maintain a patient's upper airway. Oxygen will be delivered through the breathing circuit with the following parameters: 40% oxygen at 6 liters/min flow throughout the procedure time. The MEA will be placed in the participant's oropharyngeal airway one time during an in-person visit.
