When a fairly constant fetal circulation made estimation possible, the decrease in fetal tcPO&lt;sub&gt;2&lt;\/sub&gt; synchronous with and due to the uterine contractions in more than 400 events was always delayed 50\u201360 sec. Since the time lag in the increase in fetal tcPO&lt;sub&gt;2&lt;\/sub&gt; following administration of pure oxygen to the mother was found to be of the same order of magnitude, the placental part of the delay in the oxygen transfer from mother to fetus can be assumed to be 50\u201360 sec.<\/jats:p>","DOI":"10.1159\/000299967","type":"journal-article","created":{"date-parts":[[2010,3,17]],"date-time":"2010-03-17T05:58:36Z","timestamp":1268805516000},"page":"231-236","source":"Crossref","is-referenced-by-count":2,"title":["Time Factor in Oxygen Transfer from Mother to Fetus"],"prefix":"10.1159","author":[{"given":"O.","family":"Fall","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"Ek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.A.","family":"Nilsson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Rooth","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,3,16]]},"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000299967","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T06:42:23Z","timestamp":1777617743000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000299967"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,16]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000299967","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,16]]}}}
