Lung ultrasound for evaluation of dyspnea: a pictorial review

다국어 초록 (Multilingual Abstract)

Lung ultrasound is based on the analysis of ultrasound artifacts generated by the pleura and air within the lungs. In recent years, lung ultrasound has emerged as an important alternative for quick evaluation of the patient at the bedside. Several techniques and protocols for performing lung ultrasound have been described in the literature, with the most popular one being the BLUE (Bedside Lung Ultrasound Examination) protocol developed by Lichtenstein et al, which can be utilized to diagnose the cause of acute dyspnea at the bedside. We attempt to provide a simplified approach to understanding the physics behind the artifacts used in lung ultrasound, the imaging techniques, and the application of the BLUE-protocol to diagnose the commonly presenting causes of acute dyspnea.
