Continuous positive airway pressure (CPAP) is currently the treatment of choice for the majority of patients with obstructive sleep apnea (OSA). After a CPAP trial, the initial acceptance rate is 70-80%. Patients who derive no subjective benefit from such a trial are poor candidates for home treatment with CPAP because they are likely to exhibit lower adherence and compliance rates. About 90% of OSA patients provided with CPAP apparatus will adhere to long-term CPAP treatment. Patients abandoning CPAP do so during the first few months of home therapy, a period during which close monitoring and support is warranted. Because of the strong correlation between the machine run time and effective pressure delivered at the nasal mask (90-95%), the time-counter of the CPAP device is sufficient to monitor compliance in clinical practice, allowing for early intervention in cases of suboptimal use. Longterm acceptors of CPAP display a satisfactory compliance (5-6.5 h of average daily use) which compares favourably with compliance with treatment in other chronic diseases. Lower acceptance and compliance rates have been reported in North America as compared to Europe. This could be related to cultural differences or different routines of prescription and follow-up.

阻塞性睡眠呼吸暂停患者对鼻腔CPAP的依从性。

持续气道正压通气（CPAP）是目前大多数阻塞性睡眠呼吸暂停（OSA）患者的治疗选择。经过CPAP试验后，初始接受率为70-80％。从该试验中未获得主观益处的患者是CPAP家庭治疗的较差候选人，因为他们可能表现出较低的依从性和依从率。配备CPAP装置的OSA患者中约有90％将坚持长期CPAP治疗。放弃CPAP的患者会在家庭治疗的前几个月这样做，在此期间需要密切监视和支持。由于机器运行时间与鼻罩上传递的有效压力（90-95％）之间有很强的相关性，因此CPAP设备的时间计数器足以监视临床实践中的依从性，在使用不佳的情况下允许早期干预。CPAP的长期接受者表现出令人满意的依从性（平均每天使用5-6.5小时），与其他慢性病中的治疗依从性相比具有优势。据报道，与欧洲相比，北美的接受度和合规率更低。这可能与文化差异或处方和随访的常规不同有关。
