摘要
目的通过多导睡眠图监测探讨慢性阻塞性肺疾病（COPD）缓解期夜间低氧与肺功能轻重程度，有否合并睡眠呼吸暂停（重叠综合症）及肥胖的关系。方法26例COPD患者多导睡眠图监测7h，记录血氧饱合度（SaO2）低于90％时间；平均SaO2，夜间基础SaO2与最低值的差（△SaO2）；SaO2下降大于4％的总次数。结果COPD缓解期夜间低氧和肺功能轻重程度呈正相关，合并睡眠呼吸暂停者及肥胖者均夜间低氧明显。结论COPD缓解期要针对不同病情给予夜间氧疗等措施。
Objective To evaluate the relationship between sleep hypoxemia and mild or severe impairment of lung function. Complicated to study the relation of sleep apnea and obesity in chronic obstructive pulmonary disease (COPD) by polysomnography.Methods 26 cases with COPD at remission stage were observed for 7 hours, the time of blood oxygen saturation (SaO2) under 90%, average SaO2, the baseline SaO2 and the lowest value in night were recorded. Results The SaO, in COPD at sleep was positive and proportional with the mild or severe degree impairment of lung function. The value was lower in sleep apnea and in patients with obesity. Conclusion Oxygen threapy is very important during remission stage in COPD at night.
