Lung ultrasound (LUS) has gained considerable acceptance in emergency and critical care medicine but is yet to be fully implemented in cardiology. Standard imaging protocols for LUS in acute care settings have allowed the rapid and accurate diagnosis of dyspnea, respiratory failure, and shock. LUS is greatly additive to echocardiography and is superior to auscultation and chest radiography, particularly when the diagnosis of acute decompensated heart failure is in question. In this review, the authors describe LUS techniques, interpretation, and clinical applications, with the goal of informing cardiologists on the imaging modality. Additionally, the authors review LUS findings associated with various disease states most relevant to cardiac care. Although there is extensive literature on LUS in the acute care setting, there is a dearth of reviews directly focused for practicing cardiologists. Current evidence demonstrates that this modality is an important adjunct to echocardiography, providing valuable clinical information at the bedside.

肺超声 (LUS) 在急诊和重症监护医学中获得了相当大的认可，但尚未在心脏病学中完全实施。急性护理环境中 LUS 的标准成像协议允许快速准确地诊断呼吸困难、呼吸衰竭和休克。LUS 对超声心动图有很大的补充作用，优于听诊和胸片，尤其是在对急性失代偿性心力衰竭的诊断有疑问时。在这篇综述中，作者描述了 LUS 技术、解释和临床应用，目的是让心脏病专家了解成像方式。此外，作者回顾了与与心脏护理最相关的各种疾病状态相关的 LUS 发现。尽管有大量关于急性护理环境中 LUS 的文献，缺乏直接针对执业心脏病专家的评论。目前的证据表明，这种模式是超声心动图的重要辅助手段，可在床边提供有价值的临床信息。
