Supplemental Oxygen and Oxygen Desaturations in Colonoscopies
United States280 participantsStarted 2026-05-18
Plain-language summary
This study will compare apnea and oxygen desaturation events among various methods of supplemental oxygen delivery during procedural sedation in colonoscopy patients. The goals of the study are to track apnea (10 or more seconds without respiration) and oxygen desaturation (hemoglobin oxygen saturation less than 90%) events in colonoscopy patients receiving one of three different methods of supplemental oxygen administration. The first method is standard-of-care continuous flow oxygen therapy, where a constant flow of oxygen is administered through a nasal cannula or oxygen mask. The second method is synchronized flow oxygen therapy. This is a delivery method implemented in an FDA-cleared medical device (Sovant, Dynasthetics LLC) which delivers variable-volume oxygen pulses only as the patient inhales. The delivered oxygen pulses are commensurate to the set flow rate and the patient's respiratory rate. The third method is continuous positive airway pressure therapy (CPAP), where non-invasive pressure support is given to the patient's airway to help keep their airway open. The hypothesis being tested is that synchronized flow delivery and CPAP therapy will demonstrate reductions in apnea and oxygen desaturation events compared to traditional continuous flow oxygen therapy.

* Undergoing colonoscopy procedures and receiving procedural sedation at the University of Utah Health clinic in South Jordan, Utah.
Exclusion Criteria:
* Inability/refusal of subject to provide informed consent.
* Less than 18 years of age.
* Standard colonoscopy exclusion criteria used at the GI lab at the University of Utah.
* Patients known or suspected to be pregnant.
* Patients with an ASA physical status of IV (A patient with severe systemic disease that is a constant threat to life) or V (A moribund patient who is not expected to survive without the operation).
* Patients known to have acute respiratory distress syndrome, severe COPD, or cardiovascular disease.
* If their oxygen saturation measured by pulse oximetry (SpO2) is below 93% while breathing room air prior to the procedure.
* Patients with severe medical condition(s) that in the view of the acting physician prohibits participation in the study.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
