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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether using a device that monitors oxygen levels in real time during spine surgery can help doctors give just the right amount of oxygen, reducing lung collapse afterward. 74 adults having spine surgery will be split into two groups: one gets standard fixed oxygen, the other gets oxygen adjusted based on the monitor. Lung health will be checked with ultrasound and breathing tests.

What this could mean

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

Active substance
Oxygen Reserve Index-Guided Oxygen Titration
What this could lead to
If successful, this could lead to a simple, noninvasive way to reduce lung complications after spine surgery.
What could go wrong
This is a small, early-phase study with only 74 participants, so results may not apply to everyone. The benefit over standard care may be small or absent.

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 74 people

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

Expected to start

Mar 2026

An estimate. Start dates often move.

Expected to finish

Nov 2026
