Se obtuvo registro continuo de SpO2 post-ductal y de FC desde el minuto 1 al 10 post-natal, y luego a los 15, 30 y 60 minutos. La SpO2 y FC se midieron con un ox\u00edmetro de pulso Nellcor. Para el an\u00e1lisis estad\u00edstico se utiliz\u00f3 programa Stata v.14.Resultados: Se enrolaron 324 RNT sanos, que cumplieron criterios de inclusi\u00f3n, de los cuales 160 nacieron por v\u00eda vaginal y 164 por ces\u00e1rea. La SpO2 aument\u00f3 progresivamente desde el minuto 1 (58,7%) hasta el minuto 10 (94,5%). Los RN por v\u00eda vaginal presentaron una SpO2 significativamente mayor hasta el minuto 10 post-natal respecto a los nacidos por ces\u00e1rea (p &lt; 0,001). En los neonatos nacidos por v\u00eda vaginal, la FC fue significativamente mayor en los 2 primeros minutos post-natales, y luego desde el minuto 10 al 60 (p &lt; 0,003). No se encontraron diferencias por g\u00e9nero en SpO2 y FC.Conclusi\u00f3n: En RNT la SpO2 post-natal aumenta progresivamente, siendo mayor en los primeros 10 minutos en los nacidos por v\u00eda vaginal. En los RN por v\u00eda vaginal se observ\u00f3 tambi\u00e9n una FC mayor en los primeros y \u00faltimos minutos evaluados.dos.<\/jats:p>","DOI":"10.32641\/rchped.v90i4.964","type":"journal-article","created":{"date-parts":[[2019,11,20]],"date-time":"2019-11-20T20:09:33Z","timestamp":1574280573000},"page":"384","source":"Crossref","is-referenced-by-count":7,"title":["Saturaci\u00f3n arterial de ox\u00edgeno y frecuencia card\u00edaca en reci\u00e9n nacidos de t\u00e9rmino sanos durante la primera hora post nacimiento"],"prefix":"10.32641","volume":"90","author":[{"given":"Aldo","family":"Bancalari","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heriberto","family":"Araneda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia","family":"Echeverria","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e9s","family":"Marinovic","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Camilo","family":"Manriquez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"17639","published-online":{"date-parts":[[2019,8,14]]},"container-title":["Revista Chilena de Pediatr\u00eda"],"original-title":[],"link":[{"URL":"http:\/\/www.revistachilenadepediatria.cl\/index.php\/rchped\/article\/viewFile\/964\/1193","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/www.revistachilenadepediatria.cl\/index.php\/rchped\/article\/viewFile\/964\/1245","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/www.revistachilenadepediatria.cl\/index.php\/rchped\/article\/viewFile\/964\/1245","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,4,12]],"date-time":"2021-04-12T18:27:56Z","timestamp":1618252076000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.revistachilenadepediatria.cl\/index.php\/rchped\/article\/view\/964"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,8,14]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2019,8,14]]}},"URL":"https:\/\/doi.org\/10.32641\/rchped.v90i4.964","relation":{},"ISSN":["0370-4106","0370-4106"],"issn-type":[{"value":"0370-4106","type":"electronic"},{"value":"0370-4106","type":"print"}],"subject":[],"published":{"date-parts":[[2019,8,14]]}}}
