SYNTHETIZED CONTROL STANDARD LIQUID TO BE USED FOR QUALITY CONTROL OF BLOOD GAS INSTRUMENTATION SYSTEM AND PRODUCTION THEREOF

摘要

There is disclosed a synthetic liquid control standard for use in the quality assurance of blood gas instrumentation systems which comprises an aqueous solution of a dye buffered to a pH of from about 7.1 to about 7.7 and containing sufficient bicarbonate ion to provide a pCO2 of from about 20 to about 80, ethylene glycol to provide a viscosity of from about 3 to about 9 centipoises and gaseous oxygen to provide a pO2 of from about 50 to about 400 retained in a sealed receptacle.
