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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 whether measuring oxygen levels on a facemask is reliable for critically ill patients who need a breathing tube. Doctors usually rely on pulse oximetry, but that can be misleading. The researchers will compare facemask readings with a more accurate pharyngeal measurement in 30 ICU patients to see if the simpler method works.

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 lead to better oxygen monitoring during emergency intubations, reducing the risk of dangerously low oxygen levels.
What could go wrong
This is a small, early feasibility study with only 30 participants, so results may not apply to all ICU patients. The monitoring method may still be unreliable.

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 30 people

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

Started

Expected to finish

Dec 2027

An estimate. End dates often move.

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.

18 years and older

Sex

Anyone

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: * Age ≥ 18 years * Requiring an intubation in ICU for acute respiratory failure defined as a respiratory rate ≥ 25/min or clinical signs of respiratory distress or hypoxemia defined as oxygen requirement ≥ 15L/min or FiO2 ≥80% to maintain SpO2 ≥92% or a PaO2/FiO2 ratio \<100 mmHg * With preoxygenation by noninvasive ventilation Exclusion Criteria: * Intubation for cardiac arrest * EtO2 monitoring not available * Pulsed oxygen saturation monitoring specific for the study not available * Preoxygenation by high-flow nasal oxygen therapy or bag-mask ventilation * Allergy to lidocaine (for local nasal anesthesia) * Previously * Patient not affiliated or excluded from social protection, or under law protection (namely minors, pregnant or breastfeeding women, persons deprived of their liberty by court or administrative decision) * Previously included in the study
