Using Real-Time Lung Visuals to Reduce Mental Strain and Improve Diagnosis Speed
China34 participantsStarted 2026-04-15
Plain-language summary
The goal of this clinical simulation study is to learn if a "Digital Twin" graphical lung display reduce the mental workload of clinicians. The study also evaluates if this helps physicians diagnose and manage ventilator-related crises more effectively than standard ventilator screens.
The main questions it aims to answer are:
Does the Digital Twin display lower the cognitive stress (mental workload) experienced by clinicians during a crisis? Does the Digital Twin display reduce the time it takes for clinicians to identify specific respiratory complications? Does the use of real-time physiological visualization improve the accuracy of clinical decision-making? Researchers will compare the performance of clinicians using a standard ventilator display (the "Black Box" condition) to their performance when provided with an additional synchronized 3D lung and advanced waveform display (the "Digital Twin" condition).
Participants will:
Complete four randomized mechanical ventilation crisis scenarios using a high-fidelity lung simulator (ASL 5000).
Manage scenarios involving high airway resistance, low lung compliance, auto-PEEP, and patient-ventilator asynchrony.
Undergo a 14-day "washout" period between sessions to ensure no memory bias between the control and intervention groups.
Complete a NASA-TLX survey after each scenario to measure their perceived mental, physical, and temporal demand.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
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.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
