Six patients of each treatment group were classified as having sleep stage- and body position-dependent obstructive breathing abnormalities according to the results of the baseline sleep study.<\/jats:p>\n                  <jats:p>After 3 weeks of treatment, the Epworth sleepiness score tended to be higher (p=0.08) and the ability to stay awake lower (p=0.02) in patients with dependent breathing abnormalities treated with fixed CPAP, than in the other patients. The effective pressure\/time index was significantly lower in sleep stage- and body position-dependent patients treated with fixed CPAP, than in the other patients (p=0.02). The number of hours the machine was turned on and a positive pressure applied, tended to be smaller in dependent patients treated with fixed CPAP than in independent patients of this treatment group and in patients treated with auto-CPAP. A night-to-night variability index (VI) of positive pressure changes was obtained in the auto-CPAP group. This index significantly decreased with time in the dependent patients while it remained unchanged in the independent group.<\/jats:p>\n                  <jats:p>It is concluded that auto-continuous positive airway pressure may have specific indications in a subset of obstructive sleep apnoea patients with sleep stage- and body position dependent nocturnal breathing abnormalities.<\/jats:p>","DOI":"10.1183\/09031936.01.98103501","type":"journal-article","created":{"date-parts":[[2002,10,11]],"date-time":"2002-10-11T14:37:23Z","timestamp":1034347043000},"page":"170-175","source":"Crossref","is-referenced-by-count":42,"title":["Importance of sleep stage- and body position-dependence of sleep apnoea in determining benefits to auto-CPAP therapy"],"prefix":"10.1183","volume":"18","author":[{"given":"F.","family":"S\u00e9ri\u00e8s","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"Marc","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"81","published-online":{"date-parts":[[2001,7,1]]},"reference":[{"key":"2024101808500416000_18.1.170.1","doi-asserted-by":"crossref","first-page":"520","DOI":"10.1152\/jappl.1984.57.2.520","volume":"57","year":"1984","journal-title":"J Appl Physiol"},{"key":"2024101808500416000_18.1.170.2","doi-asserted-by":"crossref","first-page":"2084","DOI":"10.1152\/jappl.1993.75.5.2084","volume":"75","year":"1993","journal-title":"J Appl Physiol"},{"key":"2024101808500416000_18.1.170.3","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm\/141.6.1569"},{"key":"2024101808500416000_18.1.170.4","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.153.1.8542125"},{"key":"2024101808500416000_18.1.170.5","doi-asserted-by":"crossref","first-page":"475","DOI":"10.1164\/ajrccm.150.2.8049832","volume":"150","year":"1994","journal-title":"Am J Respir Crit Care Med"},{"key":"2024101808500416000_18.1.170.6","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.94.07101776"},{"key":"2024101808500416000_18.1.170.7","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm\/144.3_Pt_1.494"},{"key":"2024101808500416000_18.1.170.8","doi-asserted-by":"crossref","first-page":"491","DOI":"10.1093\/sleep\/19.6.491","volume":"19","year":"1996","journal-title":"Sleep"},{"key":"2024101808500416000_18.1.170.9","doi-asserted-by":"crossref","first-page":"497","DOI":"10.1093\/sleep\/19.6.497","volume":"19","year":"1996","journal-title":"Sleep"},{"key":"2024101808500416000_18.1.170.10","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.96.09091795"},{"key":"2024101808500416000_18.1.170.11","doi-asserted-by":"crossref","unstructured":"Berthon-Jones M, Lawrence S, Sullivan CE, Grunstein R.
