May simplify radioisotope cardiac output assessment; leaves open prospective validation before clinical adoption.
This methodological paper describes a technique for measuring cardiac output using radioisotopes without the need for arterial sampling.
MacIntyre et al. (1958) studied this question. Radioisotope determination of cardiac output without arterial sampling was evaluated. A method for the radioisotope determination of cardiac output without arterial sampling was developed to be independent of critical placement or patient variability.
