摘　　要：目的:探讨脉搏传导时间(pulse transit time,PTT)技术在诊断阻塞性睡眠呼吸暂停低通气综合征(obstructivesleep apnea hypopnea syndrome,OSAHS)中的应用和价值。方法:29例鼾症患者行PTT监测,判断呼吸暂停及低通气事件,并区分阻塞性和中枢性呼吸事件,对所记录数据进行统计学分析。结果:29例PTT监测患者中,诊断为正常1例(3.4%),诊断为轻度OSAHS者3例(10.4%),诊断为中度OSAHS者10例(34.5%),诊断为重度OSAHS者14例(48.3%),诊断为中枢性OSAHS者1例(3.4%)。PTT监测所得最长阻塞呼吸暂停时间(85.00±51.80 s)、最长中枢呼吸暂停时间(52.03±20.74 s)和最低血氧饱和度(82%±16%)在男女之间差异有统计学意义(P<0.05)。结论:PTT监测仪可用于OSAHS的临床诊断,其操作简便,易被患者接受,费用经济,临床应用价值较大。Objective： To study the value of a new portable sleep respiratory recording device （Hypno PTT） on the diagnosis of obstructive sleep apnea hypopnea syndrome （OSAHS）. Methods： Overnight PTT was recorded in 29 patients being investigated for OSAHS. The apnea events and hypopnea events were determined by nasal/mouth airflow. The obstructive and central events were differentiated by the changes of PTT and nasal/mouth airflow. All recording data were analyzed by statistical methods. Results： All the patients underwent all-night PTT monitoring. The diagnosis of normal in 1 case （ 3.4% ）, mild OSAHS in 3 cases （10.4%） ,moderate OSAHS in 10 cases （34. 5% ）, severe OSAHS in 14 （48.3%）, central OSAHS in 1 （ 3.4% ）. Significant difference was found among maximum obstructive apnea duration, maximum central apnea duration and minimum Sp02 in male and female （P 〈 0.05 ）. Conclusion： Hypno PTT was an easy-handled,inexpensive and feasible portal device to diagnose OSAHS with highly value in clinical application.
