Lung Ultrasound: Cardiogenic Pulmonary Edema vs ARDS Cardiogenic Pulmonary Edema: • Smooth pleural line • AIS > 3 B-lines/ lung zone • Diffuse / homogenous • Often anterior and posterior. But may be P > A, Normal sliding • Lung consolidation is not characteristic Non-cardiogenic pulmonary edema / ARDS: • Irregular pleural line + sub-pleural opacities • AIS > 3 B-lines / lung zone • Diffuse, "patchy". Areas of sparing • +/- Reduced sliding. Lung "Pulse" • + Posterior lung consolidations & air bronchograms - Alberta Sono @UAlberta_Sono #APE #ARDS #pulmonary #edema #comparison #clinical #diagnosis #ultrasound
