Fifty women with normal and high\u2010risk pregnancies, between the 32nd and 43rd week, were voluntarily hyperventilated; in 33, fetal heart rate (FHR) acceleration or transient tachycardia were observed (reactive FHR). Of the 33 pregnancies the outcome was good in 30 (91%) as judged by the absence of perinatal death, no fetal distress in labor and no intrauterine growth retardation (IUGR). In 14 patients in whom there was no FHR response to maternal hyperventilation (non\u2010reactive FHR), the outcome of pregnancy was significantly worse; one infant died neonatally, 10 were either chronically (IUGR), or acutely distressed. Only in 3 was the outcome good (21%). The study showed that there is good correlation between a \u201creactiv\u201d FHR and favorable neonatal outcome, and between a \u201cnon\u2010reactive\u201d FHR and an unfavorable neonatal outcome.<\/jats:p>","DOI":"10.3109\/00016348209156557","type":"journal-article","created":{"date-parts":[[2009,12,8]],"date-time":"2009-12-08T18:01:48Z","timestamp":1260295308000},"page":"205-208","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Fetal Response to Voluntary Maternal Hyperventilation"],"prefix":"10.1111","volume":"61","author":[{"given":"Danny","family":"Navot","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoel","family":"Donchin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eliahu","family":"Sadovsky","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,1,11]]},"reference":[{"issue":"3","key":"e_1_2_1_2_1","first-page":"140","article-title":"Effect of PCO2 on the vascular resistance of the pregnant sheep uterus","volume":"15","author":"Fuller Guletti E.O.","year":"1972","journal-title":"Physiologist"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003081-197512000-00003"},{"key":"e_1_2_1_4_1","first-page":"142","article-title":"A study of fetal heart rate acceleration patterns","volume":"45","author":"Lee Di C.Y.","year":"1975","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-197404000-00007"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(74)90627-9"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(64)90511-3"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-196709000-00026"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(65)90589-2"},{"key":"e_1_2_1_10_1","first-page":"383","volume-title":"Scientific Foundation of Obstetrics and Gynaecology, 2nd ed","author":"Phillipp Barnes E.E.J.","year":"1977"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-197404000-00008"},{"key":"e_1_2_1_12_1","first-page":"456","article-title":"Fetal heart rate response to amniocentesis in cases of decreased fetal movements","volume":"48","author":"Ron Yaffe M.H.","year":"1976","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(71)90840-4"}],"container-title":["Acta Obstetricia et Gynecologica Scandinavica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.3109%2F00016348209156557","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.3109\/00016348209156557","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,8]],"date-time":"2023-11-08T21:03:17Z","timestamp":1699477397000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.3109\/00016348209156557"}},"subtitle":["A preliminary Report"],"short-title":[],"issued":{"date-parts":[[1982,1]]},"references-count":12,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1982,1]]}},"alternative-id":["10.3109\/00016348209156557"],"URL":"https:\/\/doi.org\/10.3109\/00016348209156557","archive":["Portico"],"relation":{},"ISSN":["0001-6349","1600-0412"],"issn-type":[{"value":"0001-6349","type":"print"},{"value":"1600-0412","type":"electronic"}],"subject":[],"published":{"date-parts":[[1982,1]]},"assertion":[{"value":"2011-01-11","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
