肺心病酸碱失衡血气值与SaO2偏移度的临床分析

目的：探讨肺心病不同类型酸碱失衡的SaO2偏移度及其临床意义。方法：为78例肺心病患者测定动脉血气，根据酸碱失衡的不同类型分为9组，应用氧离曲线方程计算出标准SaO2，再用血气实测SaO2-标准SaO2，得出SaO2偏移度，对各血气值及SaO2偏移度进行统计学处理，计算各值的均数及标准差。结果：呼酸，代酸，呼酸并代酸，代酸并呼碱时SaO2偏移度为负值；呼碱，代碱，呼碱并代酸时SaO2偏移度为正值，结论：临床上计算酸碱失衡紊乱时肺心病患者的SaO2偏移度，判定氧离曲线的偏移状，可正确评估重要脏器的真实氧供情况，为临床治疗提供帮助。

Clinical Analysis for Acid-base Unbalance and SaO2 Deviation Scale of Cor Pulmonal

Objective: The research was designed to study the deviation scale of SaO 2 of the different types of acid-base unbalance in cor pulmonal and its clinical significance. Method: The arterial blood gas analysis of 78 cases with cor pulmonal was performed. They were divided into 9 groups according to the different types of acid-base unbalance. To calculate the standard SaO 2 with oxygen equilibrium curve equation. Statistically calculated the two kinds of data above to get the average and standard deviation. Results: The deviation curve was negative when the blood gas analysis showed respiratory acidosis, metabolic acidosis, respiratory acidosis and metabolic acidosis; the deviation curve was positive when the blood gas analysis showed respiratory alkalosis, metabolic alkalosis, respiratory alkalosis and metabolic acidosis. Conclusion: Through the clinical calculation of SaO 2 deviation curve of acid-base unbalance in the cor pulmonal patients and the determination of deviation of oxygen equilibrium curve, we can evaluate correctly the actual oxygen supply for the important organs and provide assistance for the clinical treatment.
