经鼻持续气道正压通气 (NCPAP) 可改善阻塞性睡眠呼吸暂停 (OSA) 的困倦和预后。我们的目标是记录 NCPAP 合规性以及显示可消除 95% 阻塞性呼吸暂停和呼吸不足的有效压力维持的时间百分比。我们在 47 名 OSA 患者的 NCPAP 病房中建造并秘密安装了经过计时器和面罩压力传感器记录仪。在 6 个月内，每隔 2 至 8 周对受试者进行一次检查。该组平均年龄为 51 岁； 38名男性，平均体重指数为42；所有人都抱怨白天嗜睡。最初的整晚多导睡眠图显示平均呼吸暂停低通气指数 (AHI) 为 58 +/- 2.6 SEM（范围为 10 至 115）。 9 名受试者因各种原因在 3 个月内停止治疗。其余受试者 (n = 38) 的实际平均每晚使用时间为 4.7 小时，占规定总睡眠时间（依从性）的 68%。然而，有效平均使用时间为 4.3 小时，占面罩维持规定有效压力的时间的 91%。 AHI 与依从性无关，但与有效使用相关（R = 0.27048，p = 0.0006）。白天嗜睡的主观初始抱怨仅与第一次就诊期间的依从性相关（R = 0.38590，p = 0.05）。没有发现依从性的预测因素。
Nasal continuous positive airway pressure (NCPAP) improves sleepiness and prognosis in obstructive sleep apnea (OSA). Our objective was to document NCPAP compliance and the percentage of time that the effective pressure shown to eliminate 95% of the obstructive apneas and hypopneas was maintained. We built and covertly installed an elapsed timer and mask pressure transducer recorder in NCPAP units of 47 OSA patients. Subjects were seen at 2- to 8-wk intervals over 6 months. Group mean age was 51 yr; 38 males, with mean body mass index of 42; all complained of daytime sleepiness. Initial full night polysomnography demonstrated a mean apnea-hypopnea index (AHI) of 58 +/- 2.6 SEM (range, 10 to 115). Nine subjects discontinued therapy within 3 months for various reasons. In the remaining subjects (n = 38) the actual mean nightly hours of use was 4.7 which represents 68% of the stated total sleep time (compliance). However, effective mean hours of use was 4.3 which represents 91% of the time that prescribed effective pressure was maintained at the mask. The AHI did not correlate with compliance, but did correlate with effective use (R = 0.27048, p = 0.0006). Subjective initial complaints of daytime sleepiness correlated with compliance only during the first visit (R = 0.38590, p = 0.05). No predictors for compliance were found.
