摘要

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(SaO₂)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SaO₂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SaO₂的下降程度、氧降速率、持续时间都要极显著大于N-SRE组(P<0.01),SRE组SaO₂的下降最低值极显著小于N-SRE组(P<0.01)。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SaO₂的相关指标的变化,且SaO₂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 explore the relationship between variation of hemoglobin saturation and related respiratory events in patients with obstructive sleep apnea and hypopnea syndrome(OSAHS).Method:According to the SaO₂,the respiratory events were divided into two groups,followed or not followed the second events (SRE and N-SRE). Four features were extracted from SaO₂ and compared within groups under SRE versus N-SRE, and comparisons were also developed between moderate patients and severe patients.Result:ΔSaO₂,max,the duration and Dvmax was significantly higher in SRE than N-SRE(P<0.01),while Nadir was significantly lower in SRE than N-SRE(P<0.01).There was also significant difference in the blood oxygen index between moderate and severe patients.Conclusion:The change of SaO₂ is correlated with the ventilation restoration. The results also suggest that the severity of the patient's condition will affect the change of SaO₂ related indicators.This study provides information on the further study of ventilation restoration. Moreover, this study may provide a possible solution for the treatment of OSAHS.
