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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Distal Pharyngeal Airway | Experimental | Participants in this group will use the McMurray enhanced airway to have oxygen delivered throughout a TEE procedure for up to 60 minutes. |
|
| Nasal cannula group | Active Comparator | Participant in this group will receive oxygen through a nasal cannula during the TEE procedure for up to 60 minutes. |

| McMurray Enhanced Airway | Device | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Incidence of hypoxia | Determine the incidence of hypoxia defined as oxygen saturation by pulse oximetry (SPo2)= 75-89%. | during procedure (up to 60 minutes) |
| Measure | Description | Time Frame |
|---|---|---|
| Incidence of subclinical hypoxia | Determine the incidence of subclinical hypoxia defined as SPo2= 90-95%. | during procedure (up to 60 minutes) |
| Incidence of severe Hypoxia | Determine the incidence of severe hypoxia defined as SPo2<75%. |
