Abstract: 【Abstract】 Background Lung ultrasound has been widely used in the diagnosis of pulmonary diseases. However, LUS on the diagnosis and treatment of pulmonary complications to acute respiratory distress syndrome / acute lung injury(ARDS/ALI) patients instituted in lung-protective ventilation strategy are still not clear.Objective This review presents the progress in the research of the main diagnosis and therapy of pulmonary diseases and the value of lung-protective ventilation strategy by LUS in recent years. Content Ultrasound can accurately diagnose pulmonary lesions and ARDS/ALI, and guide the better application of lung-protective ventilation strategy, and evaluate the therapeutic effect. Trend Through the further research, the significance of LUS will be determined in clinical applications.That will reduce the incidence of postoperative pulmonary complications and mortality ,and improve the prognosis of patients with lung-protection ventilation strategy.
