The Efficacy of Distal Pharyngeal Airway for Oxygenation During TEE

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.

Treatment and study plan

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.

Nasal Cannula

Device

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 outcomes

  1. Incidence of hypoxia

    Time frame: during procedure (up to 60 minutes)

    Determine the incidence of hypoxia defined as oxygen saturation by pulse oximetry (SPo2)= 75-89%.

Secondary outcomes

  1. Incidence of subclinical hypoxia

    Time frame: during procedure (up to 60 minutes)

    Determine the incidence of subclinical hypoxia defined as SPo2= 90-95%.

  2. Incidence of severe Hypoxia

    Time frame: during procedure (up to 60 minutes)

    Determine the incidence of severe hypoxia defined as SPo2<75%.
