  • Title: [Evaluation of the parietal factor interfering in the measurement of cardiac output by external detection with the aid of 99mTc labelled red cells (author's transl)].

    Abstract:
    The results of a radioisotopic exploration are not independant of the physical characteristics of the tracer used. Thus in the measurement of cardiac output index by external detection, the substitution of 131I fastened on the human serum albumine by 99mTc fastened on red cells introduces a systematic average error of +20% whose origin is double. Because of the plasma or red cell kind of the tracer, the average error done on the volume is, in 130 measurements, 26% whereas that which results from the difference of photon energy is -6%. Only this last error affects the measurement of the cardiac output and, by that time, it is demonstrated that a direct determination of the cardiac output index by STEWART-HAMILTON'S relation is impossible.
