The OPT system is composed of a bedside console, a polymer mouthpiece, and a flexible tube connecting the mouthpiece to the console. The console contains a pump that creates vacuum intended to pull the soft palate anteriorly and stabilize the tongue to reduce obstruction during sleep. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> Fifty-four men and 17 women, aged 53.2 \u00b1 11.5 years (mean \u00b1 SD) had a baseline apnea\u2013hypopnea index (AHI) greater than 5 events per hour. OPT was generally well tolerated with no serious adverse events. OPT significantly decreased AHI from 34.4 \u00b1 28.9 events per hour (mean \u00b1 SD) at baseline to 20.7 \u00b1 23.3 ( p &lt; 0.001). Treatment produced an AHI less than 10 in 48% of the subjects. OPT significantly improved oxygen desaturation index ( p &lt; 0.001) and increased the percentage of the night with oxygen saturation of 90% or greater ( p = 0.028). Stage-N1 sleep shifts, total sleep-stage shifts, awakenings and the percentage of sleep time spent in N1 sleep were significantly reduced with treatment. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> This proof-of-concept study suggests that OPT can produce clinically relevant relief of OSA in certain subjects who are readily identified by PSG during trial use of the noninvasive system. OPT shows promise as a new treatment option for OSA in appropriate patients. <\/jats:p><\/jats:sec>","DOI":"10.1177\/1753465812468043","type":"journal-article","created":{"date-parts":[[2012,11,27]],"date-time":"2012-11-27T03:20:58Z","timestamp":1353986458000},"page":"3-12","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":15,"title":["A feasibility evaluation of oral pressure therapy for the treatment of obstructive sleep apnea"],"prefix":"10.1177","volume":"7","author":[{"given":"Mehran","family":"Farid-Moayer","sequence":"first","affiliation":[{"name":"Peninsula Sleep Center, Suite 707, 1828 El Camino Real, Burlingame, CA 94010, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lawrence C.","family":"Siegel","sequence":"additional","affiliation":[{"name":"Stanford University School of Medicine and ApniCure, Inc., Palo Alto, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jed","family":"Black","sequence":"additional","affiliation":[{"name":"Stanford Center for Sleep Research and Medicine, Stanford University School of Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2012,11,26]]},"reference":[{"key":"bibr1-1753465812468043","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.163.7.2004014"},{"key":"bibr2-1753465812468043","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/34.1.111"},{"key":"bibr3-1753465812468043","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200311-1571OC"},{"key":"bibr4-1753465812468043","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000042706.47107.7A"},{"key":"bibr5-1753465812468043","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1843.2012.02147.x"},{"key":"bibr6-1753465812468043","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00.00014401"},{"key":"bibr7-1753465812468043","doi-asserted-by":"publisher","DOI":"10.1378\/chest.109.6.1477"},{"key":"bibr8-1753465812468043","doi-asserted-by":"publisher","DOI":"10.5664\/jcsm.27277"},{"key":"bibr9-1753465812468043","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.2109023"},{"key":"bibr10-1753465812468043","unstructured":"FDA (2004) Ear, Nose, and Throat Devices and Dental Products Joint Advisory Panel Meeting Open Session, 6 October 2004.
