Study Details

Brief summary:

The purpose of this study is to investigate if high flow nasal cannula (HFNC), as compared to conventional nasal cannula, improves oxygenation and prevents desaturation events in obese patients undergoing colonoscopy.

Interventions and Outcome Measures

Arms

experimental: High flow cannula arm

Patients in the experimental arm (the high flow nasal cannula group) will receive heated humidified high flow oxygen of 50L/min at FiO2 of 40% throughout the colonoscopy. A patient satisfaction survey will be administered after procedure.

active comparator: Conventional cannula arm

Participants in control arm (the conventional nasal cannula group) will receive an oxygen flow of 2-5 L /min. A patient satisfaction survey will be administered after procedure.

Interventions

High Flow Nasal Cannula

Heated humidified high flow oxygen of 50 L/min at FiO2 of 40%

Conventional Nasal Cannula

Supplemental oxygen of 2-5 L/min

Patient satisfaction questionnaire

Questionnaire

Primary outcome measure

  • Incidence rate of desaturation events during procedures (desaturation events are defined by either SpO2 drops more than 5% compared to baseline SpO2 OR SpO2<90% at any time of procedures) [ Time Frame: Through out the colonoscopy procedure (after propofol induction to the end of colonoscopy) ]
