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.
由于肝素稀释导致的二氧化碳张力测量中的伪像，可通过使用采用结晶肝素的采样装置来消除。没有活塞且填充阻力低，使得可以使用小口径的23号或25号针头，从而减少动脉穿刺时的疼痛和血肿形成。
