Organ blood flow rates and cardiac output of the BALB/c mouse

1. 1. The major organ blood flows and cardiac output were determined in the anesthetized BALB/c mouse by means of indicator fractionation of labelled butanol. 2. 2. Cardiac output per unit weight of animal was twice as high as observed for rat and six-fold that of man. 3. 3. Cerebral blood flow per unit weight of organ was twice as high as measured in the rat under similar anesthesia. 4. 4. Other organ blood flows corresponded well to flows measured in larger animals. 5. 5. It was argued that indicator fractionation for periods of time exceeding 10-20 sec in the mouse may be inaccurate.
