Abstract

The acid-base status of intensive care patients is monitored on the basis of three quantities. The graphical representation which may be of help for the monitoring task is therefore cumbersome. The classical Siggaard-Andersen acid-base chart is such a representation, but it is only suited for evaluating one acid-base status at a time and not for representing acid-base paths. A new representation, obtained after a principal components transformation is presented. It is shown that the representation is characteristic for the laboratory instrument used. Its most attractive feature is that it is distortionless with respect to the three-dimensional configuration.

摘要

重症监护患者的酸碱状态基于三个量进行监测。因此，可能有助于监测任务的图形表示很繁琐。经典的西格gaard - 安德森酸碱图就是这样一种表示，但它仅适用于一次评估一种酸碱状态，而不适用于表示酸碱路径。本文提出了一种经过主成分变换后得到的新表示方法。结果表明，这种表示对于所使用的实验室仪器具有特征性。其最吸引人的特点是，它在三维配置方面是无失真的。
