Relationship between T90% and common comorbidities in patients with obstructive sleep apnea hypopnea syndrome
2020
阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome,OSAHS)是一种常见的睡眠呼吸疾病,其睡眠中发生的慢性间歇低氧(chronic intermittent hypoxia,CIH)常对全身多个系统造成损害。T90%是PSG数据中的常见指标,指整夜睡眠过程中血氧饱和度(SpO2)<90%的时间占总监测时间的百分比,与呼吸暂停低通气指数(apnea hypopnea index, AHI)和最低血氧饱和度(minSpO2)相比,能更准确、更直观地反映OSAHS患者整个睡眠期低氧的情况。多项研究表明T90%与OSAHS相关合并症密切相关。本文就T90%与OSAHS常见相关合并症的关系加以综述,有助于全面而准确地评估OSAHS患者病情的严重程度,对OSAHS合并症做到早期发现、早期诊断、早期治疗,降低合并症的风险、减少合并症的危害。
