SGA for TEE: Safe Alternative to Deep Sedation for Patients With High-risk Cardiopulmonary Disease.

Increasingly, transesophageal echos (TEEs) are being done on high risk patients. A TEE is a short procedure done with deep sedation, but poses an increased risk of apnea/ hypoxemia in those with pulmonary disease. It is desirable to avoid intubation, which adds risk. Use of supraglottic airway (SGA) may offer an alternative. The investigators hypothesize that TEEs can be done successfully with an SGA in place. The investigators propose a prospective RCT to compare TEE exams done with deep sedation to those done with an SGA.
