In all children, blood gas analysis and chest X-rays were performed within 12 h following admission to the emergency department. <i>Results:<\/i> In 55 children (68.75%) chest X-rays demonstrated lung opacities. Subjects with normal X-rays had paO<sub>2<\/sub> and SaO<sub>2<\/sub> higher than subjects with lung opacities (p < 0.0001 and p = 0.0001, respectively). Children with lung opacities almost always presented paO<sub>2<\/sub> <80 mm Hg. Sensitivity and specificity for the presence of lung opacities of paO<sub>2<\/sub> <80 mm Hg were 81 and 90%, respectively, while sensitivity and specificity of SaO<sub>2<\/sub> <95% were 92 and 40%, respectively. paO<sub>2<\/sub> <80\u00a0mm Hg in association with SaO<sub>2<\/sub> <95% had a positive predictive value for the diagnosis of pneumonia of 90.9%. <i>Conclusions:<\/i> Our study suggests that blood gas analysis, particularly paO<sub>2<\/sub>, may help in predicting the presence of lung opacities in patients aged less than 2 years. However, chest X-rays may still be needed to define the actual extension of opacities as well as the possible concomitant presence of complications.<\/jats:p>","DOI":"10.1159\/000084049","type":"journal-article","created":{"date-parts":[[2005,4,11]],"date-time":"2005-04-11T10:44:07Z","timestamp":1113216247000},"page":"176-181","source":"Crossref","is-referenced-by-count":3,"title":["Blood Gas Analysis and Chest X-Ray Findings in Infants and Preschool Children with Acute Airway Obstruction"],"prefix":"10.1159","volume":"72","author":[{"given":"Massimo","family":"Pifferi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Davide","family":"Caramella","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Angelo","family":"Pietrobelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincenzo","family":"Ragazzo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Attilio L.","family":"Boner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2005,4,12]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3109%2F02770909909068225"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097%2F00006565-199210000-00003"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1136%2Fadc.71.4.323"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2FS0022-3476%2805%2983040-9"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1159%2F000056314"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1136%2Fthx.44.4.258"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1159%2F000050490"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1159%2F000074197"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1177%2F000992288202101205"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016%2FS0140-6736%2888%2990683-6"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016%2FS0140-6736%2888%2990213-9"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016%2FS0140-6736%2889%2991308-1"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1001%2Fjama.279.4.308"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.82.3.315"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1056%2FNEJM198308113090603"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1136%2Fthx.49.4.364"}],"container-title":["Respiration"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/84049","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/84049","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T03:39:49Z","timestamp":1745465989000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000084049"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2005]]},"references-count":16,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2005,4,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000084049","archive":["Portico"],"relation":{},"ISSN":["0025-7931","1423-0356"],"issn-type":[{"type":"print","value":"0025-7931"},{"type":"electronic","value":"1423-0356"}],"subject":[],"published":{"date-parts":[[2005]]}}}
