Outcome Measures

Primary Outcomes (1)

  • Decrease recovery time

    Time measured in minutes for participants to enter post anesthesia care until the nurse marks "ready for discharge" in the medical record.

    4 hours

Secondary Outcomes (1)

  • Improve procedural conditions

    1 hour

Study Arms (2)

Standard oxygen therapy

NO INTERVENTION

Standard oxygen therapy will be initiated utilizing 2-4 liters of oxygen with a nasal cannula.

High Flow Nasal Cannula

EXPERIMENTAL

A high flow oxygen device with 100% FiO2 will be initiated prior to endoscopic ultrasound.

Other: High flow nasal cannula

Interventions

Subjects undergoing endoscopic ultrasound will receive high flow nasal cannula during the procedure
