Acute dyspnea is a common disease in emergency medicine. Mortality remains high is estimated at 15%. One third of initial diagnoses before paraclinical examination are estimated to be inaccurate. Lung ultrasound is a quick and immediate examination. Also, it is provided and performed at the bedside. The " Blue protocol " was designed by Daniel A. Lichtenstein as a diagnostic aid in dyspneic patients. It allows to obtain a diagnostic in more than 90% of acute dyspnea. However there is no validation in emergency medicine.
