Study Details

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 and Outcome Measures

Arms

experimental: Distal Pharyngeal Airway

Participants in this group will use the McMurray enhanced airway to have oxygen delivered throughout a TEE procedure for up to 60 minutes.

active comparator: Nasal cannula group

Participant in this group will receive oxygen through a nasal cannula during the TEE procedure for up to 60 minutes.

Interventions

McMurray Enhanced Airway

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.

Nasal Cannula

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

Primary outcome measure

  • Incidence of hypoxia [ Time Frame: during procedure (up to 60 minutes) ]
