title: Van Beaumont's formula is valid during haemodialysis. Spectrophotometric determination of body circulating haemoglobin.
abstract: Van Beaumont's formula is a convenient method to calculate changes in plasma volume from changes in haematocrit. The calculation is based on the assumption of a constant body red-cell volume. In order to evaluate the validity of this assumption during isovolaemic haemodialysis, we measured body circulating haemoglobin, blood volume and plasma volume by carbon monoxide dilution. No change in body circulating haemoglobin or plasma volume occurred by either method. Therefore, we conclude that van Beaumont's formula is valid during isovolaemic haemodialysis.
