The increase in its application, in part driven by the COVID-19 pandemic, along with the easy access and use of mobile and handheld devices, allows for immediate access to information, reducing the need for other radiological investigations. LUS allows for the rapid and accurate diagnosis and grading of respiratory pathology, optimisation of ventilation, assessment of weaning, and monitoring of the efficacy of surfactant therapies. This, however, must occur within the framework of accreditation to ensure patient safety and prevent misinterpretation and misdiagnosis. This narrative review aims to outline the current uses of LUS within the context of published protocols, associated pathologies, LUS scoring systems, and their applications, whilst exploring more novel uses.<\/jats:p>","DOI":"10.3390\/diagnostics15060755","type":"journal-article","created":{"date-parts":[[2025,3,17]],"date-time":"2025-03-17T15:24:56Z","timestamp":1742225096000},"page":"755","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Lung Ultrasound in Critical Care: A Narrative Review"],"prefix":"10.3390","volume":"15","author":[{"given":"Lee","family":"Berry","sequence":"first","affiliation":[{"name":"General Intensive Care Unit, University Hospital Southampton NHS Foundation Trust, Southampton SO16 6YD, UK"},{"name":"School of Health Sciences, University of Southampton, Southampton SO16 6YD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9219-4599","authenticated-orcid":false,"given":"Lucas","family":"Rehnberg","sequence":"additional","affiliation":[{"name":"General Intensive Care Unit, University Hospital Southampton NHS Foundation Trust, Southampton SO16 6YD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Groves","sequence":"additional","affiliation":[{"name":"General Intensive Care Unit, University Hospital Southampton NHS Foundation Trust, Southampton SO16 6YD, UK"},{"name":"Shackleton Department of Anaesthetics, University Hospital Southampton, Southampton SO16 6YD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Knight","sequence":"additional","affiliation":[{"name":"General Intensive Care Unit, University Hospital Southampton NHS Foundation Trust, Southampton SO16 6YD, UK"},{"name":"Shackleton Department of Anaesthetics, University Hospital Southampton, Southampton SO16 6YD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Stewart","sequence":"additional","affiliation":[{"name":"General Intensive Care Unit, University Hospital Southampton NHS Foundation Trust, Southampton SO16 6YD, UK"},{"name":"Shackleton Department of Anaesthetics, University Hospital Southampton, Southampton SO16 6YD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0165-3359","authenticated-orcid":false,"given":"Ahilanandan","family":"Dushianthan","sequence":"additional","affiliation":[{"name":"General Intensive Care Unit, University Hospital Southampton NHS Foundation Trust, Southampton SO16 6YD, UK"},{"name":"Perioperative and Critical Care Theme, NIHR Biomedical Centre, University Hospital Southampton NHS Foundation Trust, Southampton SO16 6YD, UK"},{"name":"Clinical and Experimental Sciences, Faculty of Medicine, University of Southampton, Southampton SO16 6YD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,17]]},"reference":[{"key":"ref_1","first-page":"313","article-title":"Lung ultrasound in acute respiratory failure an introduction to the BLUE-protocol","volume":"75","author":"Lichtenstein","year":"2009","journal-title":"Minerva Anestesiol."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Maggi, L., De Fazio, G., Guglielmi, R., Coluzzi, F., Fiorelli, S., and Rocco, M.
