Aim of this study was the evaluation of a supplementary transcutaneous oxygen saturation measurement with an Apple watch\u00ae in children with cyanotic heart disease.<\/jats:p><\/jats:sec>Material and methods:<\/jats:title>During a six-minute walk test, measurement of transcutaneous oxygen saturation was performed simultaneously with an Oximeter (Nellcor, Medtronic, USA) and an Apple watch\u00ae Series 7 (Apple inc, USA) in 36 children with cyanotic heart disease.<\/jats:p><\/jats:sec>Results:<\/jats:title>Median age was 9.2 (IQR 5.7\u201313.8) years. Transcutaneous oxygen saturation measurement with the Apple watch\u00ae was possible in 35\/36 and 34\/36 subjects before and after six-minute walk test. Children, in whom Apple watch\u00ae measurement was not possible, had a transcutaneous oxygen saturation < 85% on oximeter. Before six-minute walk test, median transcutaneous oxygen saturation was 93 (IQR 91\u201397) % measured by oximeter and 95 (IQR 93\u201396) % by the Apple watch\u00ae. After a median walking distance of 437 (IQR 360\u2013487) m, transcutaneous oxygen saturation dropped to 92 (IQR 88\u201395, p < 0.001) % by oximeter and to 94 (IQR 90\u201396, p = 0.013) % measured with the Apple watch\u00ae.<\/jats:p><\/jats:sec>Conclusion:<\/jats:title>In children with mild cyanosis measurement of transcutaneous oxygen saturation with an Apple watch\u00ae showed only valid results if transcutaneous oxygen saturation was > 85%, with higher values being measured with the smart watch. In children with moderate or severe cyanosis transcutaneous oxygen saturation,<\/jats:sub> measurement with the Apple watch\u00ae was not reliable and cannot be recommended to monitor oxygen saturation at home.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s1047951124025216","type":"journal-article","created":{"date-parts":[[2024,10,8]],"date-time":"2024-10-08T07:14:53Z","timestamp":1728371693000},"page":"1971-1973","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":2,"title":["Oxygen saturation measurement in cyanotic heart disease with the Apple watch"],"prefix":"10.1017","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-8969-834X","authenticated-orcid":false,"given":"Angelika","family":"Weis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Leroy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Jux","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan","family":"Rupp","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7478-5005","authenticated-orcid":false,"given":"David","family":"Backhoff","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2024,10,8]]},"reference":[{"key":"S1047951124025216_ref1","doi-asserted-by":"publisher","DOI":"10.1088\/0967-3334\/28\/3\/R01"},{"key":"S1047951124025216_ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacep.2018.10.006"},{"key":"S1047951124025216_ref2","doi-asserted-by":"publisher","DOI":"10.21037\/atm.2019.06.79"},{"key":"S1047951124025216_ref4","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/euv427"},{"key":"S1047951124025216_ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-022-02987-w"},{"key":"S1047951124025216_ref5","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-021-98453-3"}],"container-title":["Cardiology in the Young"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1047951124025216","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,8]],"date-time":"2025-04-08T10:32:10Z","timestamp":1744108330000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1047951124025216\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,9]]},"references-count":6,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2024,9]]}},"alternative-id":["S1047951124025216"],"URL":"https:\/\/doi.org\/10.1017\/s1047951124025216","relation":{},"ISSN":["1047-9511","1467-1107"],"issn-type":[{"value":"1047-9511","type":"print"},{"value":"1467-1107","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,9]]},"assertion":[{"value":"\u00a9 The Author(s), 2024.
