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 Results may not be published yet.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

Summary

This study tested three different oximeters (Masimo, Nellcor, Nonin) at various oxygen targets in 40 patients with and without COPD. The goal was to see how the choice of oximeter and target affects the amount of oxygen needed. Results could help guide safer oxygen therapy.

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 successful, this could help doctors choose the right oxygen target and oximeter to give patients the safest oxygen levels.
What could go wrong
This is a small, completed study with only 40 participants. Results may not apply to all patients or settings.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

Finished

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.

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

Inclusion Criteria: * ≥ 18 years old * On conventional oxygen therapy with SpO2 between 88 and 100% with the usual oximeter and nasal cannula. * SpO2 \< 92% in ambient air with the usual oximeter Exclusion Criteria: * No availability of the SpO2 signal with the usual oximeter * False nails or nail polish * Severe anemia documented on the last blood count during the current hospitalization (Hb \< 80g/L)
