目的:探讨睡眠呼吸暂停(SAS)患者低氧血症与高血压的关系。方法:65例疑似SAS就诊患者按不同程度呼吸紊乱指数(RDI)分组,比较各组需氧饱和度(SaO2)与血压的变化情况。结果:与正常组相比较,重度组夜间收缩压、中重度组夜间舒张压P<0.01;中重度组白昼收缩压P<0.05。夜间收缩压及舒张压与最低血氧饱和度呈负相关。结论:SAS患者夜间低氧血症是导致SAS合并高血压的因素之一。
Objective: To investigate the relationship between hypoxemia and hypertension in patients with sleep apnea (SAS). Methods: Sixty-five cases of suspected SAS patients were divided into different groups according to the degree of respiratory disorder (RDI). The changes of blood oxygen saturation (SaO2) and blood pressure were compared between groups. Results: Compared with the normal group, the nighttime systolic blood pressure in the severe group and the nighttime diastolic blood pressure in the moderate and severe groups were P <0.01; the systolic blood pressure in the moderate and severe groups was P <0.05. Nighttime systolic and diastolic blood pressure and the lowest oxygen saturation was negatively correlated. Conclusion: Nocturnal hypoxemia in SAS patients is one of the factors leading to SAS complicated with hypertension.
