重症肺部超声发源于法国，在"世界肺部超声之父"Daniel A. Lichtenstein教授的积极倡导推动发展下，重症肺部超声经历了不平凡的过去，迎来了辉煌发展的今天。笔者归纳了肺部超声的12大基本征象，总结推广应用了快速诊断急性呼吸衰竭的肺部超声急诊流程方案，用于不明原因的急性循环衰竭的肺部超声引导的限制性液体管理方案以及用于心脏骤停期间超声探查流程的心脏骤停管理肺部超声首选方案，为急危重症患者的诊治提供了很多新的思路和解决方案，成为一门新兴的交叉学科。

Critical lung ultrasound was originated from in France, as we know, professor Daniel A. Lichtenstein who was regarded as the father of critical lung ultrasound in the world, pushed the great development of critical lung ultrasound, concluded twelve signs of lung ultrasound, created the BLUE-protocol which allows fast causal diagnosis of acute respiratory failure, the FALLS-protocol used in acute circulatory failure without obvious causes and the SESAME-protocol used during cardiac arrest. Critical lung ultrasound as a new interdisciplinary subject, will provide more new ideas and solutions for diagnosis and treatments in critically ill patients.
