title: Measurement of rat lung blood flow with labelled microspheres.
abstract: A modification of the usual microsphere injection method is presented which is appropriate for rat lung blood flow measurement. The injection of microspheres into the abdominal cava vein, together with the sampling of a reference flow from the right ventricle, allowed to calculate pulmonary blood flows in the same range than the cardiac output. The differences between the two figures (about 30%) are attributed to arterio-venous shunts. The tissue distribution of the microspheres bypassing the lung capillary beds agree with this interpretation.
