Electromagnetic Determination of Carotid Blood Flow in the Anesthetized Rat

The paper describes the design and performance of the smallest iron core electromagnetic flow transducer built so far. The design is miniaturized as to the total volume of the device as well as to the size of the artery it accommodates. The use of this transducer for recording of blood flow in the smallest species of animal employed until now in blood flow research is described. Illustrations of pharmacological observations in anesthetized rats are presented.
