  • Title: [The distribution of oxygen pressure in the pial arterioles of the rat under normobaric hyperoxia].
    Author: Vovenko EP, Sokolova IB.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1992 Mar; 78(3):65-72. PubMed ID: 1330751.
    Abstract:
    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.
