Evaluation of the Impact of Pleuropulmonary Ultrasound on the Diagnosis of Dyspnea

Dyspnea is a subjective symptom perceived by the patient as a sensation of "breathing discomfort", "suffocation", "lack of air" or "difficulty inhaling or exhaling". It is a frequent reason for calling for help (8% of calls). The most seriously ill patients require the dispatch of specialized teams capable of initiating respiratory support in order to reduce the morbidity and mortality of these patients. In France, these teams are medicalized by an emergency physician within the Mobile Emergency Resuscitation Services (SMUR). This is only rarely the case outside France, where specialized paramedical teams ("advanced life support paramedic teams") can be dispatched. Apart from their role of initiating possible respiratory support, these teams (SMUR or paramedics) can initiate a diagnostic approach and therapeutics related to the suspected origin of dyspnea. However, there are many diagnos
