About this study
The ventilation (respiratory rate, tidal volume and end-tidal CO2) was monitored for patients receiving procedural sedation during endoscopy procedures in order to observe what changes commonly occur.
Read the detailed description
The literature does not currently describe which ventilation changes a clinician should watch for to keep a patient safe during procedural sedation provided by fentanyl and propofol. This observational study aimed to record the breath-by-breath respiratory rate, tidal volume and end-tidal CO2 for each patient during procedural sedation for each endoscopy procedure. Data analysis offline will aim to identify any patterns in ventilation which may precede apnea or blood oxygen desaturation. The patterns in ventilation preceding apnea or blood oxygen saturation will be compared and contrasted with the patterns of ventilation during normal ventilation periods.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
No intervention, only ventilation monitoringOther
| Study group | Role | What they receive |
|---|---|---|
| Patients receiving procedural sedation | The investigators collected ventilation data for each breath (respiratory rate, tidal volume, and end-tidal CO2) for all patients receiving procedural sedation for endoscopy. Receives: Other: No intervention, only ventilation monitoring |
What is being measured
The primary outcome is the main question the study is designed to answer.
Respiratory rate
Measured: Measured for every breath observed throughout the endoscopy procedure
Tidal volume
Measured: Measured for every breath observed throughout the endoscopy procedure

Questions about this trial
What is this clinical trial studying?
An observational study of Pulmonary Ventilation, run by University of Utah.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Respiratory rate (time frame: Measured for every breath observed throughout the endoscopy procedure). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2016; AzTrials last refreshed its copy on 27 Oct 2026.
