目的探讨双水平无创正压通气(BiPAP)对重叠综合征(OS)患者的治疗效果。方法将30例OS患者依据呼吸机应用的不同分为观察组和对照组各15例,观察组采用BiPAP治疗、对照组采用持续正压通气(CPAP)治疗,观察两组患者的治疗效果。结果治疗后,两组患者的动脉血气指标和PSG监测指标均较治疗前有改善,其中两组的PaCO2、AHI、最长呼吸暂停时间等指标治疗前后比较有统计学差异(P<0.05),而且BiPAP组患者的pH、PaCO2、AHI和最长呼吸暂停时间等指标较CPAP组改善更为明显,差异均有统计学意义(P<0.05)。结论 BiPAP治疗OS患者效果良好,能明显改善患者的血气和肺功能指标。
Objective To investigate the therapeutic effect of bi-level noninvasive positive pressure ventilation (BiPAP) on patients with overlapping syndrome (OS). Methods Thirty patients with OS were divided into observation group (15 cases) and control group (15 cases) according to different ventilator application. The observation group was treated with BiPAP and the control group was treated with continuous positive pressure ventilation (CPAP). The therapeutic effect was observed in both groups. Results After treatment, arterial blood gas index and PSG monitoring index of both groups were improved compared with those before treatment. The PaCO2, AHI and the longest apnea time of the two groups had statistical significance (P <0.05) before and after treatment, Moreover, the indexes of pH, PaCO2, AHI and the longest apnea time in BiPAP group were more obvious than those in CPAP group (P <0.05). Conclusion BiPAP treatment of OS patients with good results, can significantly improve the patient’s blood gas and lung function indicators.
