International Federation of Clinical Chemistry (IFCC): Scientific Division,Committee on pH, Blood Gases and Electrolytes:Guidelines for Transcutaneouspo2andpco2Measurement

[摘要] This document provides guidelines for the terminology, methodology,and for the interpretation of data obtained from the use of skin(transcutaneous)po2andpco2electrodes. The transcutaneoustechnique has found special application in newborn infants. Thecauses of analytical bias with respect to arterial blood gas values,and imprecision obtained with transcutaneouspco2electrodes, are reviewed. Electrode temperatures above 44°C should not be usedroutinely, and, at a measuring temperature of 44°C, the measuringsite should be changed at least every 4 h to avoid skin burns.
