1. Study Purpose

   The purpose of this study was to determine the effects of collecting arterial rather than venous blood, syringe type, and delayed analysis on blood gas, pH and base excess in heparinized blood specimens. Plastic syringes were modified to be self-filling. Arterial blood was collected directly into syringes, but venous blood was transferred through a stopcock after collection.

   Summary of Findings:

   There were no significant differences in pO2, pCO2, pH or base excess between arterial and venous blood specimens or between specimens collected in plastic rather than glass syringes. Further, storing the blood for 5 min in the modified plastic syringe had no effects on pO2, pCO2, pH or base excess.
