The aim of this study was to evaluate manual nasal continuous positive airway pressure (nCPAP) titration during daytime polysomnography compared with conventional overnight titration for @entity1 with @entity27 . Thirty-two @entity1 who underwent daytime titration were retrospectively matched (for age, sex, body mass index and apnoea/hypopnoea index (AHI)) to a group titrated overnight during the same period. Successful titration was defined as the identification of the nCPAP level (effective nCPAP (Peff)) required to eliminate respiratory events during all sleep stages. After 3 months of therapy on nCPAP at Peff, nCPAP utilization history was obtained and a group of @entity1 underwent a repeat polysomnogram (PSG) and completed a follow-up @entity25 ( @entity25 ) score. Initial titration was successful in 91% of daytime @entity1 and 91% of overnight @entity1 . The success of daytime titration was not related to diagnostic AHI or @entity25 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) @entity1 in measures of @entity25 or respiratory disturbance. Both groups demonstrated similar and significant improvements in @entity25 score. 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 @entity27 @entity1 .
