A study was undertaken to determine the blood gas effects of incompletely purging heparinized saline flush solution from an indwelling arterial catheter and pressure tubing. Hematocrit and blood gases were measured after withdrawing 0, 2, 4, 6, 8, and 10 ml of flush-blood solutions before sampling from a 20-ga radial artery catheter and 7-ft pressure tubing and stopcock. The pH and hematocrit were nearly unchanged between purging volumes of 8 and 10 ml. The PaO2 had a 2.4% error, while the PaCO2 had a 4.4% error. Because there is no standard arterial line setup, it is recommended that each ICU undertake a similar study to determine the optimal volume of aspirated flush-blood solution before blood gas sampling, in order to achieve accurate blood gas results and minimize blood waste.
