About this trial

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.

Eligibility criteria

Qualifiers

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.

Disqualifiers

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.
