65例慢性肺心病呼吸衰竭患者的血气分析及其预后探讨

Analysis of arterial blood gases in 65 Cases of chronic pulmonary heart disease with respiratory failure

对65例慢性肺心病呼吸衰竭患者血气结果和酸碱失调与其预后关系的分析,结果表明好转组和死亡组之间,PaCO_2、HCO_3^-、SaO_2、P(A-a)O_2的存在显著差异(P<0.001),这些指标与呼吸衰竭预后密切相关。严重的混合性酸碱失调和P(A-a)O_2的升高提示患者的预后不良。

To analyse 65 cases respiratory failure Patients of Chronic Pulmonary Heart Disease on arterial blood gases rresults and acid - base abnormality for their Prognosis relation, the results demonstrated that there are significant changes in PaCO_2、 HCO_3- , SaO_2、 P (A - a)O_2 between remittent groups and dead groups (P< 0.001). These indices are very associate with respiratory failure prognosis. Serious mix acid - base abnormality and P(A - a) O_2 on the increase indicated had for the grognosis of patient.
