New Dassault Systèmes Virtual Twin Experience Helps Protect Vulnerable Patients and Educate Caregivers at Saint-Louis Hospital AP-HP in Paris

Dassault Systèmes (Euronext Paris: FR0014003TT8, DSY.PA) today announced its collaboration with the Saint-Louis Hospital AP-HP in Paris on an airflow simulation and augmented reality experience to better understand the respiratory transmission of viruses and optimize patient care.

Dassault Systèmes created a unique learning experience featuring a virtual twin of the hospital’s dialysis unit – an open space where 50 people receive dialysis each week – that enabled physicians and nurses to see exactly how virus particles could circulate through the air, and understand the roles of ventilation and masks, for example, in optimizing the care of immunocompromised patients.

To create this virtual twin, Dassault Systèmes worked with building blueprints, coupled with a 3D scan of the room made on site using its HomeByMe mobile application to check for any discrepancies. It then used its SIMULIA applications powered by its 3DEXPERIENCE platform to visualize, simulate and predict the transmission of respiratory and viral particles based on different scenarios involving ventilation, the locations of medical equipment and patients in the space, mask-wearing, breathing and airflow rates. Equipped with this information, Dassault Systèmes developed the augmented reality experience enabling the stakeholders to view the virtual simulations within the real-life setting.

“Dassault Systèmes had already worked on projects at other hospitals in Paris and understood our mission to offer the highest level of care. Its solutions allowed us to visualize the production of respiratory particles, follow their trajectory, and see how they could spread from patient to patient,” said Dr. Guillaume Mellon, Attending Physician, Head of Infection Prevention and Control team, Saint-Louis Hospital AP-HP. “This incredibly innovative educational experience made our health professionals more aware of respiratory cross-transmission risks in the hospital. The entire experience exceeded my expectations.”
