Prediction of total body water from the early arterial disappearance curve of isotopic water.
With the use of tritiated water, total body water was measured by isotope dilution in 17 normal dogs. Analysis of the plasma arterial disappearance curve up to 20 minutes by a computer program using a weighted least-squares technique makes it possible to predict the final volume of dilution, with acceptable precision from the early curve.
