目的探讨自动调节持续气道正压通气(auto-CPAP)对阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的治疗效果。结果不同严重程度的OSAHS患者经过auto-CPAP治疗后临床症状明显改善,血氧饱和度(SPO2)明显升高,睡眠呼吸紊乱指数(AHl)明显降低,觉醒次数明显减少,呼吸暂停时间明显缩短,所占呼吸事件次数比例下降;低通气时间亦有明显缩短。治疗前后监测主要指标有极显著差异(P<0.01)。结论对于中重度OSAHS患者经过auto-CPAP治疗后症状好转,各项监测指标明显改善,持续气道正压通气(CPAP)是治疗阻塞性睡眠呼吸暂停低通气综合征的有效方法。 Objective To investigate the effect of auto-adjusting continuous auto-CPAP on obstructive sleep apnea-hypopnea syndrome (OSAHS). Results The symptoms of OSAHS patients with different severity were significantly improved after the auto-CPAP treatment. The oxygen saturation (SPO2) was significantly increased, the index of sleep-disordered breathing (AHl) was significantly decreased, the number of awakening was significantly reduced, the apnea time was significantly shortened, The proportion of the number of respiratory events decreased; hypoventilation time was significantly shortened. The main indicators before and after treatment were significantly different (P <0.01). Conclusions The symptoms of patients with moderate-severe OSAHS improved after auto-CPAP treatment, and the monitoring indicators improved significantly. Continuous positive airway pressure (CPAP) is an effective treatment for obstructive sleep apnea-hypopnea syndrome.
