In this study we investigated the possibility of obtaining accurate values of arterial Po(2) from specimens of capillary blood stored in glass capillary tubes and measured in an oxygen microelectrode. It has been shown that Po(2) measurements made on the Radiometer oxygen microelectrode are as accurate as those made on the macroelectrode and that the storage of blood is as satisfactory in glass capillary tubes as in glass syringes. The important feature in obtaining accurate values for arterial… CONTINUE READING
