High Flow Nasal Cannula Compared to Standard Oxygen for Endoscopic Ultrasound

High Flow Nasal Cannula Compared to Standard Oxygen Therapy for Endoscopic Ultrasound Procedure in High Risk Patients on Recovery Time and Procedural Conditions

The purpose of the study is to evaluate the use of high flow nasal cannula versus standard oxygen therapy for high-risk patients undergoing endoscopy procedures.

Patients with a higher BMI are at greater risk for lower oxygen levels which can delay the endoscopy procedure. This research is being conducted to find out if high risk patients will have a shorter recovery time and improved procedural conditions with a high flow nasal cannula versus standard oxygen therapy.

Inclusion Criteria:

• All patients age 18 years and older who present to Gonda 2 procedural area for Endoscopic ultrasound (EUS) with or without endoscopy (EGD)/biopsy/tissue sampling. with BMI ≥ 35 kg/m2 (BMI within the past 6 months in electronic medical records or at current procedure) who are able to consent will be approached for potential enrollment.

Exclusion Criteria:

• Need for general anesthesia for the procedure instead of the standard monitored anesthesia care.
• Patients undergoing combined procedure: Therapeutic EUS/combined procedures including EUS/ERCP, EUS/colonoscopy
• Patients on home oxygen therapy, or the diagnosis of "severe COPD"
• Patients with existing tracheostomy
• Inpatients undergoing EUS
• Inability to consent
• Cognitive impairment
• Blocked nasal passages
• Trauma/previous surgery to the nasopharynx
• Irregularities of the nose, face, or airway such that HFNC cannot be properly fitted
