COMPARISON BETWEEN THE CARDIAC INPUT MEASURED WITH A ROTAMETER AND OUTPUT DETERMINED BY THE DIRECT FICK METHOD IN OPEN-CHEST DOGS

Abstract
The cardiac input measured with a rota-meter agrees closely with the output determined by the direct Fick method. In calibrating the rotameter it is necessary that an adequate number of points be detd. with the temp. of the blood approx. the body temp. of the animal used because of the variability between flow and the meter reading at different flow rates with some bloods.
