双水平正压呼吸机治疗慢性肺源性心脏病急性加重期的疗效

目的　观察双水平正压呼吸机治疗慢性肺源性心脏病的临床疗效。方法　将 134例慢性肺源性心脏病急性加重期的住院患者随机分为两组 ,在原有常规综合治疗的基础上 ,治疗组 6 4例采用无创面罩双水平正压呼吸机通气治疗 ;观察双水平正压呼吸机对慢性肺源性心脏病患者临床症状、无创氧饱和度 (SaO2 )、第 1秒钟用力呼气容积(FEV1)的影响。结果　治疗组、对照组治疗后临床有效率、SaO2 、FEV1均有提高及改善 (P <0 .0 5 ) ,但治疗组治疗后上述指标提高更显著 ,两组治疗前上述参数差异无统计学意义 (P >0 .0 5 ) ,而治疗后大多数参数差异有统计学意义 (P <0 .0 5 )。结论　双水平正压呼吸机通气治疗慢性肺源性心脏病具有临床价值

Clinic effect of bilevel positive pressure ventilator on chronic pulmonary heart disease

Objective To observe the clinic effect of bilevel positive pressure ventilator on the chronic pulmonary heart disease.Methods One hundred and thirty-four patients associated with chronic pulmonary heart disease in acute exacerbation period were randomly divided into two groups.On the basis of conventional therapy,64 cases in treatment group adopted bilevel positive-pressure ventilator.Clinic curative effect,oxygen saturation(SaO 2),first second forced expiratory volume(FEV 1) were observed.Results Both groups improved the clinic curative effeiciency,SaO 2 and FEV 1(P< 0.05),but the above-mentioned indexes of the treatment group improved more distinctly.During the conventional therapy period,the indexes before the treatment showed no significant meaning between the two groups(P> 0.05).But after the treatment,most indexes showed significance through the statistic disposal(P< 0.05).Conclusion Bilevel positive-pressure ventilator on the treatment of chronic pulmonary heart disease proves clinic value.
