title: Prediction of total body water from the early arterial disappearance curve of isotopic water.
abstract: 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.
