１６９例肝性脑病４９８例次动脉血气和血电解质研究结果表明，运用呼碱和代碱预计代偿公式，可对肝性脑病呼碱并发混合型酸碱失衡作出正确的判断。凡符合实例正常可判断为呼碱并代酸；实测正常，可判断为呼碱并代碱；呼碱伴ＡＧ升高，实测正常，可判断为呼碱型三重酸碱失衡。呼碱ＰａＣＯ＿２＜４．６７ｋＰａ时，机体尽管发挥了最大的代偿能力，也不能使ｐＨ恢复正常。酸碱失衡预计代偿公式能对不同ＰａＣＯ＿２水平提供不同的判断结果。公式计算简单，便于临床应用。
169 cases of hepatic encephalopathy in 498 cases of arterial blood gas and blood electrolytes The results show that the use of alkaloids and alkaloids expected compensation formula can be used for simultaneous diagnosis of hepatic encephalopathy mixed acid-base imbalance to make the right judgments. Those who meet the normal cases can be judged as calline and acid; measured normal, can be judged as calline and alkali generation; call alkali with AG increased, measured normal, can be judged as the alkaloid triple acid-base imbalance. Calling PaCO_2 <4.67kPa, the body despite the maximum compensatory capacity, it can not make the pH back to normal. The estimated acid-base imbalance formula can provide different judgment results for different PaCO 2 levels. Formula calculation is simple, easy to clinical application.
