title: [Analysis of monitoring results of Mattress-type of sleep monitoring system in elderly patients with OSAHS].
abstract: OBJECTIVE
  To investigate the sleep monitoring feature of the MSMS in elderly patients with OSAHS.
  
  
  METHODS
  One hundred and ninety patients diagnosed with OSAHS were divided into elderly group and non elderly group according to age, then the results of MSMS were analyzed.
  
  
  RESULTS
  Majority elderly patients were with mild to moderate OSAHS. The nocturnal mean blood oxygen and the lowest oxygen were higher than non elderly group, coupled with higher percentage of the total oxygen saturation < 90% monitoring time (TS90). There was no significant difference in sleep structure between two groups, but the total sleep time of elderly group is lower than the non elderly group, the difference is statistically significant.
  
  
  CONCLUSIONS
  The elderly patients with OSAHS were less severe in nature, but the nocturnal hypoxia last longer in the elderly group. There is no significant difference in the sleep structure between the two groups. But the total sleep time decrease in elderly group. With smaller interference, the MSMS is closer to the natural sleep stustus of the subjects.
