There are a number of objectives to be achieved: - Harmonise vehicle equipment. This acquisition will allow all the inhabitants of Aube to have the same quality of care. - To enable the production and remote transmission of biomedical data and electrocardiograms (ECG) from VSAVs to the UAS control centre (Centre 15). With the publication of the MATRAS law, firefighters can undergo training to become emergency care technicians, and are authorized to carry out additional examinations (blood pressure test, ECG, ...) at the request of the UAS. These examinations are only achievable and can be tele-transmitted to the UAS using these devices. - Make it possible to optimise the orientation of victims on a care structure with an adapted technical platform, with two objectives: do not saturate the specialized technical trays by patients who do not require them (overtriage), and allow the direct orientation of patients who require these specialized trays, avoiding them the passage through an unsuitable structure with the associated loss of time (undertriage)
