Bedside Lung Ultrasound in Emergency (BLUE) Protocol[1]

Algorithm for the Use of Ultrasound in the Evaluation of Dyspnea
  • Predominant A lines + lung sliding = Asthma/COPD
  • Multiple predominant B lines anteriorly with lung sliding = Pulmonary Edema
  • Normal anterior profile + DVT= PE
  • Anterior absent lung sliding + A lines + lung point = Pneumothorax (PTX)
  • Anterior alveolar consolidations, anterior diffuse B lines with abolished lung sliding, anterior asymmetric interstitial patterns, posterior consolidations or effusions with out anterior diffuse B lines = Pneumonia
