There may be limited ability to provide NIV titration for these complex patients, and ventilatory requirements and upper airway support needs may change over time. Therefore, an automatically adjusting expiratory positive airway pressure (AutoEPAP) algorithm may offer advantages over manually adjusted EPAP for treating these patients. This study compared 4% oxygen desaturation index (ODI4%) values during the use of an AutoEPAP algorithm versus manual EPAP titration with the intelligent volume\u2010assured pressure support (iVAPS) algorithm.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This prospective, single\u2010blind, randomized, crossover study was conducted at six US sites. Patients with chronic respiratory failure (neuromuscular disease, chronic obstructive pulmonary disease, obesity hypoventilation and other aetiologies) and an apnoea\u2013hypopnoea index of &gt;5\/h who were already established NIV users underwent a single night of NIV with the iVAPS manual EPAP and iVAPS AutoEPAP in the sleep laboratory in random order.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 38 patients constituted the study population. Mean ODI4% was statistically non\u2010inferior with AutoEPAP versus manual EPAP (<jats:italic>P<\/jats:italic> &lt; 0.0001). There was no difference in the effect on ODI4% across respiratory failure subgroups. Ventilation parameters and gas exchange were similar with either NIV mode, indicating equally effective treatment of respiratory failure. Sleep parameters were improved during AutoEPAP versus manual EPAP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A single night of NIV using the iVAPS with AutoEPAP algorithm was non\u2010inferior to a single night of iVAPS with manual EPAP titration in patients with respiratory failure.Clinical Trial Registration: NCT02683772 at <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"http:\/\/clinicaltrials.gov\">clinicaltrials.gov<\/jats:ext-link><\/jats:p><\/jats:sec>","DOI":"10.1111\/resp.13546","type":"journal-article","created":{"date-parts":[[2019,4,23]],"date-time":"2019-04-23T00:00:21Z","timestamp":1555977621000},"page":"1204-1211","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Automatic EPAP intelligent volume\u2010assured pressure support is effective in patients with chronic respiratory failure: A randomized trial"],"prefix":"10.1111","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4498-5337","authenticated-orcid":false,"given":"Jeremy E.","family":"Orr","sequence":"first","affiliation":[{"name":"Department of Medicine, University of California, San Diego  La Jolla CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Coleman","sequence":"additional","affiliation":[{"name":"Department of Medicine and Neurology, Northwestern Medical Hospital  Chicago IL USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerard J.","family":"Criner","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, Lewis Katz School of Medicine at Temple University  Philadelphia PA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krishna M.","family":"Sundar","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of Utah  Salt Lake City UT USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheila C.","family":"Tsai","sequence":"additional","affiliation":[{"name":"National Jewish Health  Denver CO USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam V.","family":"Benjafield","sequence":"additional","affiliation":[{"name":"ResMed Science Center  San Diego CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maureen E.","family":"Crocker","sequence":"additional","affiliation":[{"name":"ResMed Science Center  San Diego CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leslee","family":"Willes","sequence":"additional","affiliation":[{"name":"Willes Consulting Group  San Diego CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7021-9302","authenticated-orcid":false,"given":"Atul","family":"Malhotra","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of California, San Diego  La Jolla CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6515-6204","authenticated-orcid":false,"given":"Robert L.","family":"Owens","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of California, San Diego  La Jolla CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa F.","family":"Wolfe","sequence":"additional","affiliation":[{"name":"Department of Medicine and Neurology, Northwestern Medical Hospital  Chicago IL USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,4,22]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rppneu.2014.03.009"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200406-694OC"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200607-927OC"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00018808"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/thx.2008.109728"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1159\/000364946"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1136\/thoraxjnl-2011-201081"},{"key":"e_1_2_9_9_1","first-page":"1139","article-title":"Respiratory pattern and tidal volumes differ for pressure support and volume\u2010assured pressure support in amyotrophic lateral sclerosis","volume":"14","author":"Nicholson TT","year":"2017","journal-title":"Ann.
