Successful titration was defined as the identification of the nCPAP level (effective nCPAP (<jats:italic>P<\/jats:italic><jats:sub>eff<\/jats:sub>)) required to eliminate respiratory events during all sleep stages. After 3\u2005months of therapy on nCPAP at<jats:italic>P<\/jats:italic><jats:sub>eff<\/jats:sub>, nCPAP utilization history was obtained and a group of patients underwent a repeat polysomnogram (PSG) and completed a follow-up Epworth Sleepiness Scale (ESS) score.<\/jats:p><jats:p>Initial titration was successful in 91% of daytime patients and 91% of overnight patients. The success of daytime titration was not related to diagnostic AHI or ESS score. Subjective nCPAP utilization was statistically similar in both groups. On the follow-up PSG, there were no significant differences between daytime (n=11) and overnight (n=11) patients in measures of sleep quality or respiratory disturbance. Both groups demonstrated similar and significant improvements in ESS score.<\/jats:p><jats:p>These findings suggest that the effective nasal continuous positive airway pressure can be accurately established during daytime titration in a substantial proportion of severe, symptomatic obstructive sleep apnoea patients.<\/jats:p>","DOI":"10.1183\/09031936.01.00065501","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T12:36:43Z","timestamp":1027773403000},"page":"535-541","source":"Crossref","is-referenced-by-count":19,"title":["Efficacy of daytime continuous positive airway pressure titration in severe obstructive sleep apnoea"],"prefix":"10.1183","volume":"18","author":[{"given":"J.C.","family":"Rudkowski","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Verschelden","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.J.","family":"Kimoff","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"81","published-online":{"date-parts":[[2001,9,1]]},"reference":[{"key":"2024101808550652000_18.3.535.1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199304293281704"},{"key":"2024101808550652000_18.3.535.2","doi-asserted-by":"crossref","first-page":"512","DOI":"10.1093\/sleep\/17.6.512","volume":"17","year":"1994","journal-title":"Sleep"},{"key":"2024101808550652000_18.3.535.3","doi-asserted-by":"crossref","first-page":"1169","DOI":"10.1164\/ajrccm\/147.5.1169","volume":"147","year":"1993","journal-title":"Am Rev Respir Dis"},{"key":"2024101808550652000_18.3.535.4","doi-asserted-by":"crossref","first-page":"S255","DOI":"10.1093\/sleep\/19.suppl_10.S255","volume":"19","year":"1996","journal-title":"Sleep"},{"key":"2024101808550652000_18.3.535.5","doi-asserted-by":"publisher","DOI":"10.1378\/chest.107.1.62"},{"key":"2024101808550652000_18.3.535.6","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1093\/sleep\/23.1.17","volume":"23","year":"2000","journal-title":"Sleep"},{"key":"2024101808550652000_18.3.535.7","first-page":"582","volume":"53","year":"1998","journal-title":"Monaldi Arch Chest Dis"},{"key":"2024101808550652000_18.3.535.8","doi-asserted-by":"crossref","first-page":"1755","DOI":"10.1164\/ajrccm.154.6.8970366","volume":"154","year":"1996","journal-title":"Am J Respir Crit Care Med"},{"key":"2024101808550652000_18.3.535.9","doi-asserted-by":"publisher","DOI":"10.1136\/thx.52.1.72"},{"key":"2024101808550652000_18.3.535.10","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.97.10092073"},{"key":"2024101808550652000_18.3.535.11","doi-asserted-by":"crossref","first-page":"359","DOI":"10.1164\/ajrccm.154.2.8756807","volume":"154","year":"1996","journal-title":"Am J Respir Crit Care Med"},{"key":"2024101808550652000_18.3.535.12","doi-asserted-by":"crossref","first-page":"198","DOI":"10.1093\/sleep\/21.2.198","volume":"21","year":"1998","journal-title":"Sleep"},{"key":"2024101808550652000_18.3.535.13","doi-asserted-by":"crossref","first-page":"1707","DOI":"10.1378\/chest.104.6.1707","volume":"104","year":"1993","journal-title":"Chest"},{"key":"2024101808550652000_18.3.535.14","doi-asserted-by":"crossref","first-page":"588","DOI":"10.7326\/0003-4819-127-8_Part_1-199710150-00002","volume":"127","year":"1997","journal-title":"Ann Intern Med"},{"key":"2024101808550652000_18.3.535.15","doi-asserted-by":"crossref","first-page":"947","DOI":"10.1164\/ajrccm\/143.5_Pt_1.947","volume":"143","year":"1991","journal-title":"Am Rev Respir Dis"},{"key":"2024101808550652000_18.3.535.16","doi-asserted-by":"crossref","first-page":"261","DOI":"10.1093\/sleep\/15.3.261","volume":"15","year":"1992","journal-title":"Sleep"},{"key":"2024101808550652000_18.3.535.17","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.46.2.159"},{"key":"2024101808550652000_18.3.535.18","doi-asserted-by":"publisher","DOI":"10.1378\/chest.114.4.1056"},{"key":"2024101808550652000_18.3.535.19","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.155.1.9001314"},{"key":"2024101808550652000_18.3.535.20","unstructured":"Rectschaffen A, Kales A.
