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 Results may not be published yet.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.

Summary

This trial tests whether continuous pulse oximetry with wireless alerts to clinicians can reduce serious breathing complications (respiratory depression) after surgery. Patients on two surgical wards will be monitored continuously instead of every four hours. The goal is to see if this technology improves safety and helps maintain effective pain control.

What this could mean

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

Active substance
Continuous pulse oximetry with wireless clinician notification (Covidien Nellcor Oxinet II)
What this could lead to
If effective, this monitoring could reduce life-threatening breathing complications after surgery and improve patient safety.
What could go wrong
The trial is observational in nature and may not prove the monitoring directly improves outcomes. Alarm fatigue or technical issues could limit its real-world benefit.

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.
