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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested whether a new, non-invasive finger sensor (Oxygen Reserve Index, or ORI) can predict breathing complications after coronary artery bypass surgery better than standard spirometry. Researchers measured ORI and spirometry in 142 adults before surgery and tracked lung problems like collapsed lung, pneumonia, or prolonged ventilator use for 48 hours after. The goal is to find a more accurate way to identify high-risk patients and improve their care.

What this could mean

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

What this could lead to
If ORI proves more accurate than spirometry, it could become a standard, non-invasive tool to predict breathing complications after heart bypass surgery, helping doctors take preventive steps.
What could go wrong
This is a small, single-center study with 142 participants, so results may not apply to all patients. ORI is still experimental for this use, and its real-world benefit over existing tests is unproven.

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.

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

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

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

Inclusion Criteria: * Undergoing elective coronary artery bypass grafting (CABG) surgery. * Aged 18 years or older at the time of enrollment. * Provided written informed consent to participate in the study. * Medically stable and cooperative for preoperative respiratory assessments (ORI and spirometry). Exclusion Criteria: * Refusal to participate or failure to provide informed consent. * Age under 18 years. * Left ventricular ejection fraction below 40% on preoperative evaluation. * Presence of cognitive impairment or psychiatric disorders preventing cooperation (e.g., dementia, Alzheimer's disease). * Severe anemia defined as hemoglobin level below 8 g/dL. * Undergoing emergency surgery rather than elective CABG. * Anatomical or mechanical obstruction that may impair nasal oxygenation (e.g., severe nasal septum deviation, presence of a nasogastric tube).
