The plasma volume, red cell volume, or both were measured in 170 normal, anemic, or polycythemic subjects. For anemic subjects without a serum protein abnormality or splenomegaly, the relationship between hematocrit and red cell volume was linear and predictable. In patients with a serum monoclonal globulin on electrophoresis, the plasma voluem was significantly increased for the hematocrit in ...

Pulmonary blood volume was determined by the radiocardiographic technique in 49 patients coming to cardiac catheterization. Since this method has not been directly compared with the more commonly used double injection of dye. 25 comparisons were carried out in 13 patients of the series. Agreement was good over a range of 4.5-21.1 heart cycles since there was no statistically significant differe...

Eight normotensive and eight essential hypertensive humans were studied when on high and low sodium intake. Total 24-hr exchangeable body sodium, blood volume, serum sodium concentration, hematocrit, body weight, and mean arterial pressures, when the subjects were supine and upright, were measured. Plasma and nonplasma sodium fractions, nonplasma weight, and plasma, cell, and whole blood volume...
