血气分析和酸硷测定是临床急诊中的重要内容,近来逐渐普及,认识也逐渐深入。下面介绍这方面的一些进展。一、对酸硷测定项目的认识酸硷测定项目中,血液的酸硷度(PH)和血液中的酸或硷的积聚(PCO_2和 AB)都是基本的,两者关系密切,但在概念上不能混淆。酸硷度异常,造成酸血症或硷血症;酸或硷的积聚异常,称为酸中毒或硷中毒。血液的酸硷度正常,可出现在三种情况,即:正常、代偿性酸中毒或硷中毒、复合性酸硷失衡;后两种状态常有临床重要性,因
Blood gas analysis and pH determination is an important part of clinical emergency, has gradually gained popularity, and awareness has gradually deepened. Here are some of the progress in this area. First, the understanding of the pH of the project Determination of pH in the project, the blood pH (pH) and the accumulation of acid or alkali in the blood (PCO_2 and AB) are basic, closely related, but the concept Can not be confused. Abnormal acidity, causing acidosis or acidemia; acid or alkaline accumulation abnormalities, known as acidosis or alkalosis. Normal blood pH, can occur in three situations, namely: normal, compensatory acidosis or alkalosis, complex acid-base imbalance; the latter two states are often clinically important, due to
