Lung ultrasound (LUS) is a paradigm of Point of Care Ultrasound values. First, it has no “owner” because its use has been developed by different specialties such as Intensive Care Medicine, Emergency Medicine and Internal Medicine. Secondly, its learning curve to acquire a high accuracy is relatively short and it can be performed with any kind of ultrasound machine (old, handheld devices, etc.) [1]. LUS helps in diagnosing any kind of pulmonary disease in many clinical settings and therefore different standardized protocols have been developed [2,3].
