To determine the diagnostic yield of nocturnal oximetry versus polygraphy for the diagnosis and classification of sleep apnea hypopnea syndrome (SAHS). Methods. Prospective study conducted in a university hospital. Subjects with a clinical suspicion of SAHS were included. All of them underwent home polygraphy and oximetry on the same night. A correlation was made between the apnea-hypopnea index (AHI) and the oximetry variables. The variable with the highest diagnostic value was calculated using the area under the curve (AUC), and the best cut-off point for discriminating between patients with SAHS and severe SAHS was identified. Results. One hundred and four subjects were included; 73 were men (70%); mean age was 52\u2009\u00b1\u200910.1 years; body mass index was 30\u2009\u00b1\u20094.1, and AHI\u2009=\u200929\u2009\u00b1\u200923.2\/h. A correlation was observed between the AHI and oximetry variables, particularly ODI3 (r\u2009=\u20090.850; <jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>P<\/a:mi>\n                        <a:mo>&lt;<\/a:mo>\n                        <a:mn>0.001<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>) and ODI4 (r\u2009=\u20090.912; <jats:inline-formula>\n                     <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>P<\/c:mi>\n                        <c:mo>&lt;<\/c:mo>\n                        <c:mn>0.001<\/c:mn>\n                     <\/c:math>\n                  <\/jats:inline-formula>). For an AHI\u2009\u2265\u200910\/h, the ODI3 had an AUC\u2009=\u20090.941 (95% confidence interval (CI)\u2009=\u20090.899\u20130.982) and the ODI4, an AUC\u2009=\u20090.984 (95% CI\u2009=\u20090.964\u20131), with the ODI4 having the best cut-off point (5.4\/h). Similarly, for an AHI\u2009\u2265\u200930\/h, the ODI4 had an AUC\u2009=\u20090.922 (95% CI\u2009=\u20090.859\u20130.986), with the best cut-off point being 10.5\/h. Conclusion. Nocturnal oximetry is useful for diagnosing and evaluating the severity of SAHS. The ODI4 variable was most closely correlated with AHI for both diagnosis.<\/jats:p>","DOI":"10.1155\/2020\/1891285","type":"journal-article","created":{"date-parts":[[2020,11,12]],"date-time":"2020-11-12T08:57:15Z","timestamp":1605171435000},"page":"1-6","source":"Crossref","is-referenced-by-count":6,"title":["Usefulness of Home Overnight Pulse Oximetry in Patients with Suspected Sleep-Disordered Breathing"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8771-051X","authenticated-orcid":true,"given":"Cristina","family":"Esteban-Amarilla","sequence":"first","affiliation":[{"name":"Department of Respiratory Medicine, Pitie Salpetriere University Hospital, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7656-2542","authenticated-orcid":true,"given":"Silvia","family":"Martin-Bote","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, Infanta Leonor University Hospital, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2786-2941","authenticated-orcid":true,"given":"Antonio","family":"Jurado-Garcia","sequence":"additional","affiliation":[{"name":"Physiotherapy Unit, San Juan de Dios Hospital, Cordoba, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5927-9112","authenticated-orcid":true,"given":"Ana","family":"Palomares-Muriana","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, Hospital de Alta Resoluci\u00f3n, Puente Genil, Cordoba, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4439-4243","authenticated-orcid":true,"given":"Nuria","family":"Feu-Collado","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, Reina Sof\u00eda University Hospital, C\u00f3rdoba, Spain"},{"name":"Maim\u00f3nides Biomedical Research Institute of Cordoba (IMIBIC), C\u00f3rdoba, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1608-1795","authenticated-orcid":true,"given":"Bernabe","family":"Jurado-Gamez","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, Reina Sof\u00eda University Hospital, C\u00f3rdoba, Spain"},{"name":"Maim\u00f3nides Biomedical Research Institute of Cordoba (IMIBIC), C\u00f3rdoba, Spain"},{"name":"School of Medicine, University of C\u00f3rdoba, C\u00f3rdoba, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.163.3.2005065"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.5665\/sleep.4654"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/s0140-6736(05)71141-7"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.201311-2012oc"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2013.281250"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/s1579-2129(11)70034-9"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1136\/thx.2010.152272"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.201612-2497oc"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/s1579-2129(07)60137-2"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1378\/chest.120.2.625"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1136\/thx.54.11.968"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm\/147.1.50"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1007\/s11325-015-1251-6"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1053\/rmed.2003.1480"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.5664\/jcsm.6506"},{"key":"16","doi-asserted-by":"crossref","first-page":"737","DOI":"10.5664\/jcsm.27032","article-title":"Clinical guidelines for the use of unattended portable monitors in the diagnosis of obstructive sleep apnea in adult patients","volume":"3","author":"N.
