The Determination of Cardiac Output by a Continuous Recording System Utilizing Iodinated (I131) Human Serum Albumin
II. Clinical Studies
A method previously described for the determination of cardiac output by the injection of iodinated (I131) human serum albumin has been extended to a study of its application to patients. A technic suitable for clinical use has been described and values obtained have been compared with those simultaneously determined by cardiac catheterization. The average deviation from Fick principle values was ±8.3 per cent over a range from –8.4 per cent to +18.7 per cent. Certain precautions in technic necessary for accuracy have been stressed.
