title: A new device for arterial blood gas sampling.
abstract: Artifacts in CO2 tension measurements owing to heparin dilution are eliminated by use of a sampling device employing crystalline heparin. The absence of a plunger and the low resistance to filling allows the use of small, 23- or 25-guage needles, thus reducing pain during arterial puncture and hematoma formation.
