We investigated such false air leakage using a new chest drainage unit with a built-in CO2-detector and an electronic chest drainage unit.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Two types of chest drainage units were tested in a simple porcine model: A well-known electronic chest drainage unit and a new chest drainage unit with integrated CO2-detector. We created a setup of true air leakage\u2014a parenchymal lesion, and false air leakage\u2014allowing air to flow into the thoracic cavity alongside the chest drain.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n We demonstrated that the new chest drainage unit with a built-in CO2-detector can distinguish between experimentally induced true air leakage and false air leakage.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Available chest drainage systems do not allow direct assessment of true or false air leakage, which may increase chest drain duration unnecessarily. The integration of a CO2-sensitive color indicator into a chest drainage unit allows simple distinction between false air leak and true air leak, which may improve postoperative management.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/15533506211047446","type":"journal-article","created":{"date-parts":[[2021,9,25]],"date-time":"2021-09-25T21:09:05Z","timestamp":1632604145000},"page":"385-389","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["New Chest Drainage Unit with Integrated CO\n 2<\/sub>\n -Detector Demonstrates False Air Leak"],"prefix":"10.1177","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3675-1204","authenticated-orcid":false,"given":"Jens","family":"Eckardt","sequence":"first","affiliation":[{"name":"Department of Cardiothoracic Surgery, Odense University Hospital, Odense, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marike","family":"Lijkendijk","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, Odense University Hospital, Odense, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter B.","family":"Licht","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, Odense University Hospital, Odense, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Stenger","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, Odense University Hospital, Odense, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,9,25]]},"reference":[{"key":"bibr1-15533506211047446","doi-asserted-by":"publisher","DOI":"10.21037\/jtd.2017.04.31"},{"key":"bibr2-15533506211047446","doi-asserted-by":"publisher","DOI":"10.1007\/s00268-010-0943-0"},{"issue":"3","key":"bibr3-15533506211047446","first-page":"271","volume":"6","author":"Mueller MR","year":"2014","journal-title":"J Thorac Dis"},{"key":"bibr4-15533506211047446","doi-asserted-by":"publisher","DOI":"10.1016\/j.thorsurg.2015.07.002"},{"key":"bibr5-15533506211047446","doi-asserted-by":"publisher","DOI":"10.1007\/s11748-016-0646-z"},{"issue":"2","key":"bibr6-15533506211047446","first-page":"86","volume":"10","author":"Bardell T","year":"2003","journal-title":"Canc Res J"},{"key":"bibr7-15533506211047446","doi-asserted-by":"publisher","DOI":"10.1016\/j.thorsurg.2010.03.002"},{"key":"bibr8-15533506211047446","doi-asserted-by":"publisher","DOI":"10.1097\/MCP.0000000000000282"},{"key":"bibr9-15533506211047446","volume":"37","author":"Eckardt J","year":"2020","journal-title":"Surg Technol Int"}],"container-title":["Surgical Innovation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/15533506211047446","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/15533506211047446","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/15533506211047446","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T07:23:04Z","timestamp":1777706584000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/15533506211047446"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,9,25]]},"references-count":9,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2022,6]]}},"alternative-id":["10.1177\/15533506211047446"],"URL":"https:\/\/doi.org\/10.1177\/15533506211047446","relation":{},"ISSN":["1553-3506","1553-3514"],"issn-type":[{"value":"1553-3506","type":"print"},{"value":"1553-3514","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,9,25]]}}}
