The study also evaluates if this helps physicians diagnose and manage ventilator-related crises more effectively than standard ventilator screens.\n\nThe main questions it aims to answer are:\n\nDoes 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).\n\nParticipants will:\n\nComplete four randomized mechanical ventilation crisis scenarios using a high-fidelity lung simulator (ASL 5000).\n\nManage scenarios involving high airway resistance, low lung compliance, auto-PEEP, and patient-ventilator asynchrony.\n\nUndergo a 14-day \"washout\" period between sessions to ensure no memory bias between the control and intervention groups.\n\nComplete a NASA-TLX survey after each scenario to measure their perceived mental, physical, and temporal demand.",[75,76,77,78],"Mechanical Ventilation","Clinical Competence","Education Curriculum","Self Concept",[80,81,82,83],"medical simulation","mechanical ventilation","clinical competence","mental pressure load","NOT_YET_RECRUITING","2026-04-06",{"date":87,"type":88},"2026-04-13","ACTUAL",{"date":90,"type":69},"2026-04-15",{"date":92,"type":69},"2026-07-31",{"name":5,"class":6},1]
