OSAHS多平面诊断的发展现状

The development of multi-level diagnosis of obstructive sleep apnea hypopnea syndrome

OSAHS患者通常伴有打鼾、睡眠结构紊乱，频繁发生血氧饱和度下降、白天嗜睡、注意力不集中等症状，并可能导致高血压、冠心病、糖尿病Ⅱ型等多器官多系统损害。患者于睡眠期间引起呼吸暂停和低通气的上气道阻塞不但涉及解剖及生理学等诸因素，而且往往并不局限于单一层面，

The obstruction of OSAHS patient is not limited to a single level. These blockages of multiple sites trend to influence each other and participate in a complex process. To date, the determination of obstruction is often depends on empirical judgment of clinician. However, it is a key issue to find out which level of obstruction is most significant. The article will focus on the commonly used values in laboratory examinations and their relationship with AHI. Based on the existing work, we decide to make a comprehensive analysis of their predictive value.
