Breathing with air revealed that oxygen tension in arterioles practically does not depend on the diameter of vessels under study in rats. Whereas in breathing with oxygen, oxygen tension sharply decreased along the course of the microvessel bed. The above decrease seems to be due to exclusion of hemoglobin's dumping function and the effect of such factors as the ratio of arterioles surface's extension to the volume of their blood and the velocity of blood flow in pial arterioles.
用空气呼吸时发现，大鼠小动脉中的氧分压实际上并不取决于所研究血管的直径。而在用氧气呼吸时，氧分压沿微血管床的行程急剧下降。上述下降似乎是由于血红蛋白卸载功能的排除以及诸如小动脉表面积与其血液体积之比和软脑膜小动脉中血流速度等因素的影响。
