The role chest radiography plays in intensive care units (ICU) is unlike its role elsewhere because in the ICU a patient's underlying disease is usually known. Furthermore, additional diseases that develop in the ICU-such as pneumonia, hemorrhage, edema, lung collapse and effusion-often are radiographically indistinguishable. Nevertheless, an ICU radiograph of the chest is valuable, mainly in identifying such complications as malpositioned intravenous catheters, Swan-Ganz catheters, pacemakers, nasogastric tubes, endotracheal tubes, chest tubes, and mediastinal tubes, and ectopic gas related to mechanical ventilation. Understanding the limitations of the portable ICU chest film in the diagnosis of specific diseases and being alert to possible iatrogenic complications will increase the usefulness of ICU chest radiography.
胸部X光在重症监护病房（ICU）所起的作用与其在其他地方的作用不同，因为在ICU中患者的基础疾病通常是已知的。此外，在ICU中出现的其他疾病，如肺炎、出血、水肿、肺萎陷和积液，在X光片上往往难以区分。然而，ICU的胸部X光片很有价值，主要用于识别诸如静脉内导管、 Swan-Ganz导管、起搏器、鼻胃管、气管内导管、胸管和纵隔管位置不当等并发症，以及与机械通气相关的异位气体。了解便携式ICU胸部X光片在特定疾病诊断中的局限性，并警惕可能的医源性并发症，将提高ICU胸部X光检查的效用。
