AG200与PSG在OSAHS诊断中的应用

AG200 and polysomnography in patients with obstructive sleep apnea-hypopnea syndrome

目的:研究PSG及气道阻塞定位仪(AG200)评估OSAHS的临床应用价值。方法:67例经PSG确诊为OSAHS的患者,应用AG200进行整夜监测。对AHI、呼吸暂停指数(AI)、低通气指数(HI)、最低血氧饱和度(LSaO2)等参数进行比较。结果:PSG和AG200所测得的AI、AHI、LSaO2比较均差异有统计学意义(均P<0.01),HI差异无统计学意义(P>0.05)。PSG和AG200所测得的AHI、AI、HI、LSaO2均有较高相关性(r=0.870、0.743、0.374、0.716,均P<0.01)。结论:AG200对OSAHS患者可做出初步诊断,对判断OSAHS患者上气道阻塞部位有较好的参考价值。

Objective：To study the clinical value of polysomnography（PSG）and ApneaGraph（AG200）in the diagnosis evaluation of obstructive sleep apnea hypopnea syndrome（OSAHS）.Method：From January to December in 2012,67 OSAHS patients diagnosed by PSG were examined by AG200.The apnea hypopnea index（AHI）,hypopnea index（HI）,apnea index（AI）,the lowest oxygen saturation（LSaO2）was were detected and the results were analyzed statistically.Result：Significant differences were observed in AI,AHI,LSaO2 between AG200and PSG（P〈0.05,respectively）.No statistically significant difference was found in HI.The differences in HI between AG200 and PSG were not significant（P〉0.05）.AHI,HI and LSaO2 was were significantly correlated between AG200 and PSG（r=0.870,0.743,0.374,0.716,P〈0.01）.Conclusion：AG200could not replace PSG but could identify the level of upper airway obstruction.
