目的探讨患者白天嗜睡等症状的原因,评估经鼻持续气道内正压通气(nCRAP)治疗对阻塞性睡眠呼吸暂停患者睡眠结构的影响。方法选择2001-2004年广东省佛山市第一人民医院呼吸科34例OSAS病人在睡眠多导生理记录仪监测下,进行nCPAP治疗,观察治疗前后呼吸紊乱指数、血氧饱和度和睡眠结构的变化。结果治疗后呼吸紊乱指数下降,最低血氧饱和度上升,睡眠结构明显改善。结论nCRAP能有效地改善OSAS病人的睡眠结构和呼吸紊乱。
Objective To investigate the causes of daytime drowsiness and other symptoms in patients with nasal continuous positive airway pressure (nCRAP) treatment of sleep apnea patients with obstructive sleep disturbance. Methods From 2001 to 2004, 34 patients with OSAS in Department of Respiratory Medicine, First People ’s Hospital of Foshan City, Guangdong Province were enrolled in this study. NCPAP was monitored under sleep polysomnography recorder. The changes of respiratory disorder index, oxygen saturation and sleep architecture were observed before and after treatment . Results After treatment, the index of respiratory disorder decreased, the minimum oxygen saturation increased, and the sleep structure improved significantly. Conclusion nCRAP can effectively improve sleep architecture and respiratory disturbance in OSAS patients.
