A-Lines vs B-Lines on Lung POCUS A-Lines: • Predominately horizontal lines • A-lines are repeated horizontal & parallel lines which are equidistant from the pleura. Commonly seen in dry lungs, asthma, COPD and also a pneumothorax. B-Lines • Predominately vertical lines • B-lines are vertical lines that come from the pleura, extend to the bottom of the screen and move with respirations. 3 or more B-lines in a region is considered pathologic. Commonly seen in pulmonary edema, ARDS, pneumonia and other pathology. - MCW EM Ultrasound @MCW_EM_US #ALines #BLines #Lung #POCUS #pulmonary #clinical #comparison
