Its polygraphic features involve progressive increases in esophageal pressure (Pes), terminated by arousal (AR) as defined by the American Sleep Disorders Association (ASDA). With the arousal there is an abrupt decrease in Pes, called Pes reversal. However, Pes reversal can be seen without the presence of an AR. We performed spectral analysis on electroencephalographic data from a central lead for both AR and nonarousal (N-AR) events obtained from 15 UARS patients (eight men and seven women). Delta band activity was increased before and surrounding Pes reversal regardless of the presence or absence of AR. In the period after Pes reversal, alpha, sigma, and beta activity showed a greater increase in AR events than in N-AR events. The Pes measures were identical leading up to the point of reversal, but showed a longer-lasting and significantly greater decrease in respiratory effort after an AR. The data indicate that substantial electroencephalographic changes can be identified in association with Pes events, even when ARs cannot be detected according to standard criteria; however, visually identifiable electroencephalographic arousals clearly have a greater impact on ongoing inspiratory effort.<\/jats:p>","DOI":"10.1164\/ajrccm.162.2.9901026","type":"journal-article","created":{"date-parts":[[2013,4,4]],"date-time":"2013-04-04T14:23:08Z","timestamp":1365085388000},"page":"406-411","source":"Crossref","is-referenced-by-count":87,"title":["Upper Airway Resistance Syndrome"],"prefix":"10.1093","volume":"162","author":[{"given":"JED E.","family":"BLACK","sequence":"first","affiliation":[{"name":"Stanford University Sleep Disorders Clinic, Stanford, California; and Department of Psychology, University of Melbourne, Melbourne, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"CHRISTIAN","family":"GUILLEMINAULT","sequence":"additional","affiliation":[{"name":"Stanford University Sleep Disorders Clinic, Stanford, California; and Department of Psychology, University of Melbourne, Melbourne, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"IAN M.","family":"COLRAIN","sequence":"additional","affiliation":[{"name":"Stanford University Sleep Disorders Clinic, Stanford, California; and Department of Psychology, University of Melbourne, Melbourne, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"OSCAR","family":"CARRILLO","sequence":"additional","affiliation":[{"name":"Stanford University Sleep Disorders Clinic, Stanford, California; and Department of Psychology, University of Melbourne, Melbourne, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2000,8,1]]},"reference":[{"key":"2026032708225555900_B1","doi-asserted-by":"crossref","first-page":"781","DOI":"10.1378\/chest.104.3.781","article-title":"A cause of excessive daytime sleepiness: the upper airway resistance syndrome.","volume":"104","author":"Guilleminault","year":"1993","journal-title":"Chest"},{"key":"2026032708225555900_B2","first-page":"S13","article-title":"From obstructive sleep apnea syndrome to upper airway resistance syndrome: consistency of daytime sleepiness.","volume":"15","author":"Guilleminault","year":"1992","journal-title":"Sleep"},{"key":"2026032708225555900_B3","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1016\/S1042-3699(20)30822-0","article-title":"Upper airway resistance syndrome.","volume":"7","author":"Guilleminault","year":"1995","journal-title":"Oral Maxillafac.
