oa South African Medical Journal - Exercises with a blood gas analyser



In a study to assess the accuracy of p02 and pC02 electrodes as used for blood determinations, it was found that the error, using the p02 electrode, was 1,53 � 1,82%, and that for the pe02 electrode was 1,315 � 1,12%. Studies were also carried out on the diffusion of O2 and CO2 through plastic syringes; it was found that such syringes are quite suitable for the storage of arterial blood for blood gas analysis if they are kept at 2�' - 5� C.
