Abstract: 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 PSGAHI (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 between DAMICS-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.
