【摘要】：目的:探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者睡眠过程中的血氧(SaO_2)变化与事件恢复情况的相关关系。方法:将呼吸事件按照恢复通气情况的不同分为伴随第二事件(SRE,未恢复正常通气)和不伴随第二事件(N-SRE,恢复正常通气)两类,以提取事件后SaO_2变化段的4个特征值作为指标,比较不同病情的患者各血氧指标的差异性,以及个体内归一化后SRE血氧变化组和N-SRE血氧变化组各指标的对比。结果:SRE血氧变化组和N-SRE血氧变化组成对t检验的结果显示,SRE组SaO_2的下降程度、氧降速率、持续时间都要极显著大于N-SRE组(P0.01),SRE组SaO_2的下降最低值极显著小于N-SRE组(P0.01)。中度和重度患者的血氧指标对比均具有显著性差异。结论:OSAHS患者的不同病情会影响SaO_2的相关指标的变化,且SaO_2的相关指标和事件恢复情况存在相关关系。本研究为呼吸事件恢复的进一步研究提供更多的依据,了解如何能从呼吸事件中较快恢复正常通气为治疗OSAHS提供可能的方案。
[Abstract]:Objective: to investigate the relationship between the changes of SAO _ 2 during sleep and the recovery of events in patients with obstructive sleep apnea hypopnea syndrome (OSAHS).Methods: respiratory events were divided into two groups according to the different conditions of restored ventilation: the second event (no normal ventilation) and the second event (N-SRE). The four characteristic values of the SaO_2 changes after the event were extracted as indicators.To compare the differences of blood oxygen indexes in patients with different conditions, and to compare the indexes of SRE and N-SRE after normalization in vivo.There was significant difference in blood oxygen index between moderate and severe patients.Conclusion the changes of relative indexes of SaO_2 may be affected by the different condition of the patients with SaO_2, and there is a correlation between the related indexes of SaO_2 and the recovery of events.This study provides more evidence for further research on the recovery of respiratory events and how to recover normal ventilation quickly from respiratory events to provide a possible regimen for the treatment of OSAHS.
