目的:探讨阻塞性睡眠呼吸暂停综合征患者的临床特征及评价疗效。方法:回顾分析70例阻塞性睡眠呼吸暂停综合征患者PSG监测数据。结果:随着呼吸紊乱指数的增加,年龄、体重指数、最长呼吸暂停时间、最低SaO_2%、平均SaO_2%下降等指标在轻度与中、重度SAS之间差异显著;70例患者中伴有高血压52.9%、糖尿病5.7%、冠心病21.4%。结论:OSAS是一种具有潜在危险的疾痛,对OSAS早期诊断治疗是预防发生严重并发症的关键。 Objective: To investigate the clinical characteristics and evaluation of patients with obstructive sleep apnea syndrome. Methods: A retrospective analysis of 70 patients with obstructive sleep apnea syndrome PSG monitoring data. Results: The indexes of age, body mass index, the longest apnea time, the lowest SaO_2% and the average SaO_2% decreased with the increase of respiratory disorder index. There were significant differences between mild and moderate and severe SAS in 70 patients Hypertension was 52.9%, diabetes 5.7% and coronary heart disease 21.4%. CONCLUSIONS: OSAS is a potentially dangerous pain and the key to early diagnosis and treatment of OSAS is to prevent serious complications.
