The Transport of Radioactive Inorganic Phosphate by the Pulmonary Circulation

Abstract

Radio-phosphorus in the form H₃P³²O₄, injected in aqueous solution, is found to give flow-dilution curves and values for cardiac output indistinguishable from those obtained with T-1824 in normal anesthetized dogs. The fairly rapid disappearance of the P³² from systemic blood is a technical advantage if the measurement of output is to be repeated at short intervals.
