What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study will test three ways of giving oxygen to 280 adults during colonoscopy sedation: standard continuous flow, breath-synchronized pulses via the Sovant device, and CPAP. Researchers will track how often patients have breathing pauses or low oxygen levels. The goal is to find which method keeps patients safest during the procedure.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Breath-synchronized oxygen (Sovant device) and CPAP
What this could lead to
If successful, this could identify a safer way to give oxygen during colonoscopy sedation, reducing breathing complications.
What could go wrong
This is an early-stage observational study, not testing a new treatment. Results may not apply to other procedures or patient groups.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 280 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

May 2026

An estimate. Start dates often move.

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult patient * No life threatening conditions * 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.
