International Federation of Clinical Chemistry (IFCC). Scientific Division. Committee on pH, Blood Gases and Electrolytes. Guidelines for transcutaneous pO2 and pCO2 measurement.

This document provides guidelines in the terminology, methodology, and in the interpretation of data obtained from the use of skin (transcutaneous) pO2 and pCO2 electrodes. The transcutaneous technique has found special application in newborn infants. The causes of analytical bias with respect to arterial blood gas values and imprecision obtained with transcutaneous pO2 and pCO2 electrodes are reviewed. Electrode temperatures above 44 degrees C should not be used routinely, and at a measuring temperature of 44 degrees C, the measuring site should be changed at least every 4 h to avoid skin burning.

IFCC document stage 3, draft 1, dated 1989 02 01. An approved IFCC recommendation. IFCC method (1988) for tonometry of blood: reference materials for pCO2 and pO2. International Federation of Clinical Chemistry Scientific Division. Committee on pH, Blood Gases and Electrolytes.

A reference method for tonometry of blood is described. The document covers the theory of tonometry, the materials and equipment needed, and essential aspects of the tonometry procedure for blood. The partial pressures of oxygen and carbon dioxide in tonometered blood are accurately known and therefore this blood is recommended for assessing the accuracy of blood gas analyzers. Tonometry of blood samples from patients may also be used in the determination of acid-base quantities and hemoglobin-oxygen affinity, e.g. p50.

Método IFCC (1988) para tonometria de sangre; materiales de referencia para Pco2 y Po2 / IFCC método (1988) from blood of tonometry; Pco2 and Po2 reference of material

Se describe un método de referencia para tonometría de la sangre. El documento abarca la teoria de la tonometría, los materiales y el equipo necesarios y los aspectos esenciales del procedimiento de tonometría para sangre. Las presiones parciales de oxígeno y dióxido de carbono en sangre tonometrada son conocidas exactamente y, por lo tanto, esta sangre se recomienda para evaluación de la exactitud de analizadores de gases sanguíneos. La tonometría de muestras de sangre de pacientes puede ser también usada en la determinación de cantidades ácido-base y de la afinidad hemoglobina-oxigeno e.g.Pso.
