The % sleep time spent under nCPAP was estimated on 3 consecutive days in 28 patients receiving long-term nCPAP, by comparing machine-use periods with sleep periods identified by home actigraphy.<\/jats:p><jats:p>The mean difference between pTST and aTST was 2.5\u2005min. The correlation coefficient between aTST and pTST was 0.90. Daily use of nCPAP over the 3 study days was 388\u00b1114\u2005min. nCPAP was used 41\u2013100% (82\u00b117% (mean\u00b1sd)) of sleep time detected by actigraphy. Some patients used nCPAP during nonsleep periods.<\/jats:p><jats:p>In conclusion, comparison of nasal continuous positive airway pressure use with sleep time estimated by home actigraphy shows marked individual differences in the % sleep time under nasal continuous positive airway pressure. These results suggest that actigraphic estimation of sleep time under nasal continuous positive airway pressure could provide a better index than simple daily use of the device to evaluate the impact of treatment in sleep apnoea.<\/jats:p>","DOI":"10.1183\/09031936.04.00089604","type":"journal-article","created":{"date-parts":[[2008,9,19]],"date-time":"2008-09-19T17:25:02Z","timestamp":1221845102000},"page":"891-895","source":"Crossref","is-referenced-by-count":25,"title":["Wrist-actigraphic estimation of sleep time under nCPAP treatment in sleep apnoea patients"],"prefix":"10.1183","volume":"23","author":[{"given":"F.","family":"Gagnadoux","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"X.L.","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Rakotonanahary","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Vidal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Fleury","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"81","published-online":{"date-parts":[[2004,6,1]]},"reference":[{"key":"2024101810504735000_23.6.891.1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199304293281704"},{"key":"2024101810504735000_23.6.891.2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199903183401104"},{"key":"2024101810504735000_23.6.891.3","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.164.11.2102028"},{"key":"2024101810504735000_23.6.891.4","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200005113421901"},{"key":"2024101810504735000_23.6.891.5","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.163.1.2001008"},{"key":"2024101810504735000_23.6.891.6","doi-asserted-by":"publisher","DOI":"10.1034\/j.1399-3003.1999.14a30.x"},{"key":"2024101810504735000_23.6.891.7","first-page":"862","volume":"1","year":"1981","journal-title":"Lancet"},{"key":"2024101810504735000_23.6.891.8","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(94)91522-9"},{"key":"2024101810504735000_23.6.891.9","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(98)10532-9"},{"key":"2024101810504735000_23.6.891.10","first-page":"204","volume":"359","year":"2001","journal-title":"Lancet"},{"key":"2024101810504735000_23.6.891.11","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000042706.47107.7A"},{"key":"2024101810504735000_23.6.891.12","doi-asserted-by":"publisher","DOI":"10.1378\/chest.107.2.375"},{"key":"2024101810504735000_23.6.891.13","doi-asserted-by":"publisher","DOI":"10.1378\/chest.119.2.460"},{"key":"2024101810504735000_23.6.891.14","first-page":"165","volume":"150","year":"1989","journal-title":"West J Med"},{"key":"2024101810504735000_23.6.891.15","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm\/147.4.887"},{"key":"2024101810504735000_23.6.891.16","doi-asserted-by":"crossref","first-page":"149","DOI":"10.1164\/ajrccm.149.1.8111574","volume":"149","year":"1994","journal-title":"Am J Respir Crit Care Med"},{"key":"2024101810504735000_23.6.891.17","doi-asserted-by":"publisher","DOI":"10.1136\/thx.49.3.263"},{"key":"2024101810504735000_23.6.891.18","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.160.4.9802027"},{"key":"2024101810504735000_23.6.891.19","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.96.09112356"},{"key":"2024101810504735000_23.6.891.20","doi-asserted-by":"crossref","first-page":"83","DOI":"10.1093\/sleep\/3.1.83","volume":"3","year":"1980","journal-title":"Sleep"},{"key":"2024101810504735000_23.6.891.21","doi-asserted-by":"crossref","first-page":"389","DOI":"10.1093\/sleep\/5.4.389","volume":"5","year":"1982","journal-title":"Sleep"},{"key":"2024101810504735000_23.6.891.22","doi-asserted-by":"crossref","first-page":"461","DOI":"10.1093\/sleep\/15.5.461","volume":"15","year":"1992","journal-title":"Sleep"},{"key":"2024101810504735000_23.6.891.23","doi-asserted-by":"crossref","first-page":"285","DOI":"10.1093\/sleep\/18.4.285","volume":"18","year":"1995","journal-title":"Sleep"},{"key":"2024101810504735000_23.6.891.24","unstructured":"Rechtschaffen A, Kales A, A manual of standardized terminology techniques and scoring system for sleep stages of human subjects.
