Objective To analyze the diagnostic value of digital area medicine information cybernetic system (DAMICS) in diagnosing obstructive sleep apnea hypopnea syndrome (OSAHS).Methods Seventy-six patients [male 64, female 12, with a mean age of (46.58±14.32)] with suspected OSAHS were monitored by DAMICS and polysomnography (PSG) for 7 h. The apnea hypopnea index (AHI) of PSG served as gold standard for the diagnosis of OASHS. The diagnostic value was evaluated by comparing PSG-AHI with DAMICS-AHI.Results There was no significant difference in mild patients according to groups of PSG-AHI (P>0.05). There was no significant difference in stertorous and mild patients according to groups of DAMICS-AHI (P>0.05). Significant positive correlation was found betweenDAMICS-AHI and PSG-AHI (r=0.967,P=0.000). With PSG-AHI≥5 as the diagnostic standard of OSAHS and PSG-AHI≥15 as diagnostic of severe OSAHS, receiver operating characteristic (ROC) curves were drawn. According to ROC curves, a cut-off point of 7.6 was identified as the best point for diagnosing OSAHS with sensitivity of 93.8% and specificity of 100%. Another cut-off point of 14.15 was identified as the best point for diagnosing severe OSAHS with sensitivity of 93.9% and specificity of 96.3%.Conclusion DAMICS is a valuable device with highly sensitivity and specificity in diagnosis of OSAHS.%目的：评价数字化全病区医学信息监测与控制系统(digital area medicine information cybernetic system，DAMICS)在睡眠呼吸暂停综合征(obstructive sleep apnea hypopnea syndrome，OSAHS)中的诊断价值。方法收集2014年9月-2015年4月在我院呼吸内科就诊的76例打鼾患者，男64例，女12例，年龄18~81(46.58±14.32)岁。对每名患者同时进行1次7 h的DAMICS监测和多导睡眠监测(polysomnography，PSG)，以PSG的呼吸暂停低通气指数(apnea hypopnea index，AHI)为诊断OSAHS的金标准，对PSG和DAMICS监测所得出的AHI做比较，评价其诊断价值。结果以PSG所测AHI分组， DAMICS-AHI和PSG-AHI在轻度组中的差异无统计学意义(P＞0.05)。以DAMICS所测AHI分组，两者在鼾症组和轻度组中的差异无统计学意义(P＞0.05)。DAMICS-AHI和PSG-AHI呈正相关(r=0.967，P=0.000)，以PSG-AHI≥5作为诊断金标准绘制ROC曲线，得出DAMICS-AHI≥7.6时，约登指数最大，灵敏度93.8%，特异度100%。以PSG-AHI≥15绘制ROC曲线，得出中重度患者DAMICS-AHI最佳诊断点为14.15，灵敏度93.9%，特异度96.3%。结论 DAMICS对OSAHS的诊断准确性高，有较大的临床应用价值。
