Abstract

Objective: To explore the differences of polysomnography parameters of obstructive sleep apnea hypopnea syndrome(OSAHS) between children and adults.Methods: The sleep of 37 pediatric OSAHS and 35 adult OSAHS patients was monitored.Several parameters,including the apnea index(AI),hypopnea index(HI),apnea hypopnea index(AHI),the lowest oxygen saturation(LSaO_2) and the longest apnea time were counted,and the percent of stages of NREM and REM,including the microarousal index was calculated.Results: Many parameters,such as AI,HI,AHI,LSaO_2 and the longest apnea time were significantly different between the two groups.The sleep structure of pediatric OSAHS was similar with that of normal children,but different from that of the adult group.Conclusion: The difference of PSG parameters is significant between pediatric OSAHS and adult OSAHS.The standard of adult PSG does not fit for child PSG.
