近十余年来,睡眠呼吸障碍受到人们的重视,它对血液动力学、心血管功能及生活质量均有很大影响。但对它的监测、诊断需要多种仪器,费用大,需时也多。因此,需要寻找发现率高。快速又经济的方法。近年来的研究表明,上气道梗阻是阻塞性睡眠呼吸障碍的重要因素。部分患者显示有固定性解剖学变化,例如扁桃体肿大等;但多数在局部检查时未见显著器质性病变。其梗阻部位可能为松弛的咽部组织或舌根。鉴于某些肺功能检查能发现上气道阻塞引起的气流阻塞。Sander和Haponic等经临床观察证明,流量-容积曲线(Flow-volume curve,F-VC)对阻塞性及混合性睡眠暂停综合征有一 For more than ten years, sleep-disordered breathing has drawn great attention. It has a great influence on hemodynamics, cardiovascular function and quality of life. However, its monitoring, diagnosis requires a variety of instruments, costly, takes more time. Therefore, we need to find the high rate of discovery. Fast and economical way. In recent years, studies have shown that upper airway obstruction is an important factor in obstructive sleep apnea syndrome. Some patients showed fixed anatomical changes, such as tonsil enlargement; but most of the local examination showed no significant organic disease. The obstruction site may be loose pharyngeal tissue or tongue base. In view of some pulmonary function tests can be found in upper airway obstruction caused by airflow obstruction. Sander and Haponic and other clinical evidence that flow-volume curve (Flow-volume curve, F-VC) on obstructive and mixed sleep apnea syndrome have a
