A micromethod for the determination of pH and PCO2 in human cerebrospinal fluid

Abstract

With the Astrup apparatus which is used for the microdetermination of pH and Pco₂ in whole blood we have determined the pH and Pco₂ of cerebrospinal fluid (CSF). The CSF was obtained from patients with different neurological diseases but without respiratory alterations. As all other chemical tests showed no abnormalities, the acid-base composition of the samples may also be considered as normal.
