Intravascular inhomogeneous distribution of oxygen in arterioles of rat cremaster muscle.
Previously, cross-sectional oxygen distribution in microvessels was assumed to be homogeneous. The oxygen profile in the arterioles of rat cremaster muscle was measured using microspectrophotometry and a PO(2) microelectrode, showing a drop in SO(2) as well as PO(2) close to the vascular wall with a flat PO(2) profile in the perivascular tissue.
