The BLUE-protocol (Bedside Lung Ultrasonography in Emergency) proposes a new way for diagnosing acute hemodynamic pulmonary edema (AHPE). It uses the potential of lung ultrasound. Using a simple equipment without Doppler and a single universal probe, the BLUE-protocol analyses the artifacts and dynamic arising from the pleural line. The profile which associates, at the anterior chest wall, lung sliding with lung rockets, is called the B-profile. Lung sliding is a twinkling visible at the pleural line indicating absence of pneumothorax and correct movement of the visceral pleura with respect to the motionless parietal pleura, indicating correct lung implication. Lung rockets are several (more than 2) B-lines visible between two ribs in a longitudinal scan. The B-line is a hydro-aeric artifact which combines seven criteria: A comet-tail, arising from the pleural line, moving in concert with lung sliding, long, well defined, erasing the A-lines (repetitions of the pleural line) and hyperechoic. The B-profile has for the diagnosis of AHPE, 97% sensitivity and 95% specificity. Lung ultrasound is therefore able to provide a piece of information which can be coupled with traditional echocardiography for an accurate diagnosis of hemodynamic pulmonary edema (a direct sign, whereas the detection of cardiac anomalies makes an indirect sign).
