Stroke volume (SV) and CO, as measured by BR and transthoracic echocardiography, were compared. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; The mean gestational age (GA) was 31.3 weeks and mean birth weight (BW) was 1,563 g. Overall, 690 measurements were analysed for trending ability by 4-quadrant and polar plots. For non-weight-indexed measurements, 377 (54.6%) lay outside the 5% exclusion zone, the concordance rate was poor (77.2%) with a high mean angular bias (28.6\u00b0), wide limits of agreement and a poor angular concordance rate (17.4%). Neither GA, BW nor respiratory support mode affected trending data. Patent ductus arteriosus, postnatal age, and CO level had variable effects on trending data. Trending data for 5 and 10% exclusion zones were also compared. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; The ability of BR to track changes in CO is not interchangeable with CO changes as measured by echocardiography. BR, as a trend monitor for changes in CO or SV to determine clinical decisions around interventions in neonatology, should be used with caution. <\/jats:p>","DOI":"10.1159\/000518656","type":"journal-article","created":{"date-parts":[[2021,9,9]],"date-time":"2021-09-09T21:03:57Z","timestamp":1631221437000},"page":"600-608","source":"Crossref","is-referenced-by-count":6,"title":["Bioreactance Cardiac Output Trending Ability in Preterm Infants: A Single Centre, Longitudinal Study"],"prefix":"10.1159","volume":"118","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9245-3282","authenticated-orcid":false,"given":"Lizelle","family":"Van Wyk","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4267-1825","authenticated-orcid":false,"given":"Johan","family":"Smith","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Lawrenson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2136-6533","authenticated-orcid":false,"given":"Carl J.","family":"Lombard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Willem-Pieter","family":"de Boode","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2021,9,9]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1213\/ANE.0b013e3181f08a5b"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1007\/s10877-012-9334-4"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1023\/a:1009982611386"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1007\/s40140-014-0062-9"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1038\/s41390-018-0081-1"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1053\/j.jvca.2011.01.003"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1213\/ANE.0000000000000725"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000003530"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/aer401"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1186\/s40635-016-0087-0"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1136\/fn.74.2.f88"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1159\/000365278"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1136\/fetalneonatal-2011-301090"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1007\/s10877-019-00330-y"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2008.10.016"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1088\/0967-3334\/37\/9\/R88"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/2635151"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1186\/1824-7288-40-60"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1053\/j.jvca.2016.06.016"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1007\/s10877-018-0217-1"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1186\/cc11814"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/11.suppl_i.49"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1007\/s00134-016-4258-y"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1159\/000337295"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1038\/jp.2017.100"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.4037\/aacnacc2018402"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1055\/s-0041-1726123"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.1055\/s-0040-1713603"},{"key":"ref29","doi-asserted-by":"publisher","DOI":"10.1016\/j.earlhumdev.2020.105153"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/518656","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/518656","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:17:56Z","timestamp":1745421476000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000518656"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021]]},"references-count":29,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2021,10,20]]},"published-print":{"date-parts":[[2021,10,26]]}},"URL":"https:\/\/doi.org\/10.1159\/000518656","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.16594718","asserted-by":"subject"}]},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"value":"1661-7800","type":"print"},{"value":"1661-7819","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021]]}}}
