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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 simulation study tests whether a 'Digital Twin' lung display—a 3D animation of lung function—can reduce mental workload and speed up diagnosis for doctors managing breathing machines. Thirty-four ICU physicians will handle four simulated breathing emergencies, once with standard monitors and once with the Digital Twin. The goal is to see if the extra visual information helps them think more clearly and act faster.

What this could mean

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

Active substance
Real-time graphical lung function visualization (Digital Twin) device
What this could lead to
If successful, this could lead to better training tools and decision-support displays that help doctors manage breathing machines more quickly and with less stress.
What could go wrong
This is a small simulation study with 34 participants, not a real patient trial. Results may not translate to actual hospital settings, and the benefit over standard monitors may be minimal.

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 34 people

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

Expected to start

Apr 2026

An estimate. Start dates often move.

Expected to finish

Jul 2026

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.

Ages

18 to 65 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

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: * Licensed physicians currently practicing in intensive care units (ICU), neuro-intensive care units (NICU), or respiratory departments. * For the Junior Stratum: Physicians currently in a standardized residency training program or in their first two years of a sub-specialty fellowship. For the Senior Stratum: Senior attending physicians or senior fellows with more than 5 years of experience in intensive care medicine. * Basic proficiency in operating the mechanical ventilators used in the study (e.g., Hamilton, Dräger, or Puritan Bennett). * Willingness to participate in two simulation sessions separated by a 14-day interval. Exclusion Criteria: * Prior formal training or significant experience using the ASL 5000 / RespiSim "Digital Twin" or Aurora interface. * Physical limitations that prevent the operation of a mechanical ventilator or the viewing of a digital monitor. * Refusal to provide informed consent for video recording of the simulation session for data adjudication.
