Sampling method: PROBABILITY_SAMPLE
Study population: Hemodynamic assessment will target patients with circulatory failure and / or sepsis in emergency unit

Brief summary: After a basic training to echocardiography, emergency physicians will have to answer simple clinical questions about circulatory failure mechanisms. The objective of the study is to assess the agreement between these answers and those of the expert physician in patients admitted in the emergency department with a circulatory failure due to sepsis or not. Emergency physicians will volunteer to take part in a basic training on echocardiography. The training will include 4 hours of theory, 2 hours of interactive clinical cases and 6 hours of tutored practice at patients' bedside (10 to 15 examinations). The objective of the practice sessions will be to learn the technical grounds of transthoracic echocardiography (TTE), the different views and to identify the anatomical structures. The second part of the study will start after the training. Each eligible patient will be successively assessed by two investigators: one emergency physician recently trained and the expert physician. The echocardiography will be performed as soon as possible in the emergency department before or after the initiation of treatment without delaying it. The order of hemodynamic assessments will be random depending on the availability of the investigators; both assessments will however be performed within 30 minutes. Each investigator will independently read the echocardiography in real time at patients' bedside. They will then answer a limited list of standardized questions using two-choice answers or predefined choices. Finally investigators will choose a therapeutic proposition among a predefined list based on the answers. Only the results of the echocardiography performed by the expert physician will be used in patient management.
