Different arterial sampling increases indicator-dilution cardiac output error; leaves open whether site standardization reduces variability in practice or trials.
What is the reproducibility of the indicator-dilution technique for estimating cardiac output when sampling from different arterial sites?
The reproducibility of indicator-dilution cardiac output measurements is significantly affected by the choice of arterial sampling sites, suggesting nonuniform dye distribution.
