The SARS-CoV-2 health crisis identified a number of issues, in particular the adaptation and monitoring of the management of patients in a protracted crisis. The SENS project (Environmental and Neurosensory Simulation) proposes an innovative solution to respond to emergencies or disasters. Indeed, it aims to design and deploy an ultra fidelity simulation center within the Toulouse Hospital allowing reproduction in a controlled environment of climatic conditions (rain, wind, smoke, light/dark, etc.) and sensory (sounds, smells, vision, vibrations,) occurring in a disaster theatre (natural, industrial, etc.). A digital virtual reality environment will be developed and integrated within This innovative and unique device in the world will allow the treatment of psychotraumatised patients through exposure therapy; as well as improving the reception, guidance, sorting and care of victims of catastrophic health situations, by improving the skills and response capacities of front-line health workers in neurosensory overstimulation. The implementation of this ultra-fidelity simulation prototype will lead to an improvement in the resilience of the Occitan health system, and an increased protection of caregivers and disaster victims.
