title: [Compare the differences between automatic analysis and manual analysis of apnea events in polysomnogram].
abstract: OBJECTIVE
  To investigate whether there are differences on the diagnose of sleep apnea hypopnea syndrome between automatic analysis and manual analysis of respiration events in polysomnogram.
  
  
  METHODS
  Sixty snoring human was selected randomly and monitored separately by sleep monitor in seven hour at night, sleep monitor would produce a poly sonogram, firstly polysomnogram was analysis by the software of sleep monitor and then by the manual operation. Finally data were processed by statistical analysis.
  
  
  RESULTS
  There were significant differences between automatic analysis and manual analysis of polysomnogram on apnea hypopnea index,apnea index, hypopnea index and long apnea. Data of manual analysis were more consistent with clinic symptoms of patients than automatic analysis.
  
  
  CONCLUSIONS
  The result of automatic analysis of polysomnogram had a deviation to the diagnosis of pathogenetic, in order to improve the accuracy of clinic diagnosis, polysomnogram should be analysis by manual operation generally.
