Current neonatal guidelines recommend a 3:1 compression:ventilation ratio; however, the most effective ratio of delivering chest compressions (CC) remains controversial. We report a case of a male infant at 24 weeks' postmenstrual age weighing 650 g on a background of preterm labor. At initial assessment the infant appeared floppy and apneic with a heart rate (HR) of 50-60 beats\/min. Mask ventilation was ineffective, thus continuous CC (90\/min) with asynchronous ventilations (60\/min) was started. HR, blood pressure, oxygen saturation, cerebral oxygenation, respiratory function, and exhaled carbon dioxide (ECO&lt;sub&gt;2&lt;\/sub&gt;) were continuously measured during CPR. Return of spontaneous circulation defined as HR &gt;60\/min was achieved after 90 s of CPR. Mask leak significantly increased during CC. During bradycardia (HR \u223c50\/min), ECO&lt;sub&gt;2&lt;\/sub&gt; indicated correct tube placement and an increase of ECO&lt;sub&gt;2&lt;\/sub&gt; &gt;12 mm Hg was associated with rapid increase in HR &gt;60\/min.<\/jats:p>","DOI":"10.1159\/000357609","type":"journal-article","created":{"date-parts":[[2014,1,27]],"date-time":"2014-01-27T07:47:39Z","timestamp":1390808859000},"page":"200-204","source":"Crossref","is-referenced-by-count":24,"title":["Respiratory Function and Near Infrared Spectroscopy Recording during Cardiopulmonary Resuscitation in an Extremely Preterm Newborn"],"prefix":"10.1159","volume":"105","author":[{"given":"Elliott S.","family":"Li","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7141-1523","authenticated-orcid":false,"given":"Po-Yin","family":"Cheung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerhard","family":"Pichler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Khalid","family":"Aziz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georg M.","family":"Schm\u00f6lzer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2014,1,24]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1161%2FCIRCULATIONAHA.110.971119"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1161%2F01.CIR.101.14.1743"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1136%2Fadc.2009.174003"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.jpeds.2011.09.017"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1186%2F1757-7241-20-73"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1203%2FPDR.0b013e3182125f7f"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.resuscitation.2006.04.015"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1371%2Fjournal.pone.0070895"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1203%2FPDR.0b013e318220c1e0"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.jpeds.2013.01.026"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/357609","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/357609","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:29:42Z","timestamp":1745432982000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000357609"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":10,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2014,3,1]]},"published-print":{"date-parts":[[2014,3,20]]}},"URL":"https:\/\/doi.org\/10.1159\/000357609","archive":["Portico"],"relation":{},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"type":"print","value":"1661-7800"},{"type":"electronic","value":"1661-7819"}],"subject":[],"published":{"date-parts":[[2014]]}}}
