Evaluation of the sampling technique and storage of blood using the B 109 Arterial Blood Sampler syringe

To evaluate the B 109 Arterial Blood Sampler (Radiometer), 10 different samples were analyzed for Pco2, Po2, and pH. The aerobic sampling technique, followed by storage for 2 h in water at 1 degrees C, induced small, but clinically insignificant, changes in the measured values.
