An indwelling arterial line or arterial punctures are necessary to obtain PaO<sub>2<\/sub> for the calculation of OI. Oxygenation can be continuously and noninvasively assessed using pulse oximetry. The use of the oxygen saturation index (OSI = MAP \u00d7 FiO<sub>2<\/sub> \u00d7 100 : SpO<sub>2<\/sub>) can be an alternate method of assessing the severity of HRF. <b><i>Objective:<\/i><\/b> To evaluate the correlation between OSI and OI in the following: (1) neonates with HRF and (2) a lamb model of meconium aspiration syndrome. <b><i>Methods:<\/i><\/b> Human neonates: a retrospective chart review of 74 ventilated late preterm\/term neonates with indwelling arterial access and SpO<sub>2<\/sub> values in the first 24 h of life was conducted. OSI and OI were calculated and correlated. Lamb model: arterial blood gases were drawn and preductal SpO<sub>2<\/sub> was documented in 40 term newborn lambs with asphyxia and meconium aspiration. OI and OSI were calculated and correlated with pulmonary vascular resistance (PVR). <b><i>Results:<\/i><\/b> Mean values of OSI and OI showed a correlation coefficient of 0.952 in neonates (mean value of 308 observations in 74 neonates) and 0.948 in lambs (mean value of 743 observations in 40 lambs). In lambs, with increasing PVR, there was a decrease in OI and OSI. <b><i>Conclusion:<\/i><\/b> OSI correlates significantly with OI in infants with HRF. This noninvasive measure may be used to assess the severity of HRF and PPHN in neonates without arterial access.<\/jats:p>","DOI":"10.1159\/000369774","type":"journal-article","created":{"date-parts":[[2015,1,13]],"date-time":"2015-01-13T03:13:37Z","timestamp":1421118817000},"page":"161-166","source":"Crossref","is-referenced-by-count":99,"title":["Oxygen Saturation Index and Severity of Hypoxic Respiratory Failure"],"prefix":"10.1159","volume":"107","author":[{"given":"Munmun","family":"Rawat","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Praveen K.","family":"Chandrasekharan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashley","family":"Williams","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sylvia","family":"Gugino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmon","family":"Koenigsknecht","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Swartz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang Xing","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bobby","family":"Mathew","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jayasree","family":"Nair","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satyan","family":"Lakshminrusimha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2015,1,13]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097\/PCC.0b013e3181b0653d"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199702273360901"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200002173420704"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinthera.2010.04.023"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1542\/peds.113.3.559"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1378\/chest.08-2239"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1203\/PDR.0b013e3180db29fe"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1203\/PDR.0b013e3181bab0c7"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1038\/pr.2014.186"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1002\/bimj.200510192"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1542\/peds.99.5.681"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/369774","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/369774","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T14:05:39Z","timestamp":1745417139000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000369774"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":11,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2015,3,1]]},"published-print":{"date-parts":[[2015,3,26]]}},"URL":"https:\/\/doi.org\/10.1159\/000369774","archive":["Portico"],"relation":{},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"value":"1661-7800","type":"print"},{"value":"1661-7819","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015]]}}}
