title: [Diagnostic value of portable monitor device in patients with potential obstructive sleep apnea hypopnea syndrome].
abstract: OBJECTIVE
  To evaluate the diagnostic value of portable monitor device (PMD) in potential obstructive sleep apnea hypopnea syndrome (OSAHS) patients.
  
  
  METHODS
  All patients met the inclusion criteria were asked to finish the questionniar and underwent anthropometric measurements, and then completed polysomnography (PSG) test and PMD test simultaneously. The correlation between AHI-PMD and AHI-PSG, between MinSaO2-PMD and MinSaO2-PSG were analyzed by Spearman analysis. T test was used to compare the correlation coefficient between the two groups; ROC analysis was used to evaluate the sensitivity and specificity of PMD in diagnosis of OSAHS, and got the Cut-off value between moderate and severe OSAHS and mild OSAHS.
  
  
  RESULTS
  Through PSG test, of all the 111 cases, including 4 simple snoring cases, accounting for 3.6%, OSAHS patients with 107 cases, accounting for 96.4% which including 11 patients (9.9%) with mild, 17 patients (15.3%) with moderate, 79 patients (71.2%) with severe. The correlation of AHI-PMD and AHI-PSG between moderate and severe OSAHS patients was stronger than simple snoring and mild OSAHS patients. The coefficient test between the two groups was statistically significant (P=0.026). The correlation of MinSaO2-PMD and MinSaO2-PSG was statistically significant (P<0.001), the correlation of MinSaO2-PMD and MinSaO2-PSG between moderate and severe OSAHS group and snoring and mild OSAHS group was not statistically significant (P=0.270). A statistically significant correlation between AHI-PMD and AHI-PSG was found (P<0.001). PMD had a sensitivity and specificity of 96.9% and 86.7%, respectively (AUC=0.990, 95%CI 0.970-1.000). The cut-off value between moderate and severe OSAHS and mild OSAHS was AHI-PMD≥12 times/h.
  
  
  CONCLUSIONS
  PMD had a satisfactory sensitivity and specificity for diagnosing and judging the severity of moderate and severe OSAHS.
