Abstract
Objective In order to analyze the clinical characteristics and the characteristics of polysomnograpgy in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) at night.Methods 289 OSAHS patients were grouped according to the condition of lowest oxygen saturation,of which 69 cases of mild group,lowest oxygen saturation at 85%~90%,moderate group in 73 cases,lowest oxygen saturation at 80%~85%,147 cases of severe group,lowest oxygen saturation at <80%.Clinical characteristics of different lowest oxygen saturation in patients with OSAHS including age, body mass index (BMI), neck circumference,Epworth sleep scale(ESS),oxygen desaturation index (ODI),apnea hypopnea index (AHI),total apnea time,the longest apnea time and total hypopnea time and the longest hypopnea time,non-rapid eye movements(NREM) stage 1,NREM stage 2,NREM stage 3 and rapid eye movements(REM) sleep the percentage of total sleep time period was analyzed.Results The 3 groups in age,ESS score,total hypopnea time and the longest hypopnea time,REM and NREM stage 1 during the between BMI and ODI,AHI,total apnea time, the longest apnea time,NREM stage 2 and NREM stage 3 there are obvious differences, performance was significantly higher than that of mild group and moderate group in severe group were BMI, ODI, AHI, neck circumference, total apnea time,the longest apnea time between the three groups were significantly different in severe group NREM stage 2 higher than in the mild group, severe group and mild group in a period of less than NREM stage 3.Conclusion The patients with BMI,neck circumference affects patients with the lowest blood oxygen saturation;hypoxia degree of patients with more severe patients,oxygen desaturation index and apnea index is higher,total apnea time,longest apnea time,NREM stage 2 longer,while the patients with deep sleep NREM stage 3 sleep time is short.关键词
