What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at how different oxygen level targets and two types of oximeters affect the amount of oxygen given to patients in the intensive care unit. Researchers will test four combinations of target (90% or 94% oxygen saturation) and oximeter (Philips or Nonin) in 40 adults after heart surgery. The goal is to see which setup uses less oxygen while keeping patients safe, potentially reducing oxygen toxicity.

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 study could help doctors choose better oxygen targets and oximeters to reduce oxygen waste and risk of oxygen toxicity.
What could go wrong
This is a small, early-stage study with only 40 participants, mostly light-skinned. Results may not apply to all patients or settings.

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.

Participants

About 40 people

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

Started

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 of age * Patients admitted to postoperative cardiac surgery intensive care unit * Presence of an arterial catheter Specific for the extubate patient * Ongoing on conventional oxygen therapy at moderate flow (up to a maximum of 5L/min) with SpO2 between 88 and 100% with the usual oximeter and nasal cannula. * SpO2 \< 92% ambient air Specific for the intubate patient FiO2 \<= 0.60 with SpO2 between 88 and 100% with usual oximeter SpO2 \< 92% with FiO2 0.21 Exclusion Criteria: * No SpO2 signal with oximeter in use * False nails or nail polish * Methemoglobinemia \>0.015 on last available arterial gas * Patient in isolation (multi-resistant bacteria, C-Difficile, SARS-CoV-2 ...) Specific for the extubate patient * Expected to use another respiratory support within one hour of inclusion (NIV or nasal high flow oxygen) Planned extubation within one hour of inclusion
