171 Effect of Liquid Heparin Cn Pc02 Measurement in Micro Blood Samples

Abstract

Anticoagulation of micro blood samples with large volumes of liquid Na heparin (LSH) affects the accuracy of PCO2 measurement. To estimate the magnitude of this effect we measured PCO2, varying the CO2 level, sample size and type of heparin. Whole blood was equilibrated to three levels of CO2 concentration: 7% (PCO2≅50 torr), 5% (≅35 torr) 2% (≅16 torr… (More)
