The Relationship

Abstract Measurements of red cell volume and plasma volume in eight normal women confirm that, in relation to body weight, red cell volume is distinctly lower in women than in men and plasma volume only slightly lower. The relationship between body hematocrit and venous hematocrit (0.90) was found not to be significantly different from that of men.

The Relationship

Abstract 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 30%, and the total blood volume was increased in 45%. The frequency of an elevated plasma volume was higher in patients with a markedly increased level of monoclonal protein. Reductions of abnormal proteins with chemotherapy were associated with declines in plasma volume. For a specific concentration, the serum viscosity was highest in patients with IgM proteins and lowest in patients with IgG globulins. Marked elevations in viscosity were noted only in sera with macroglobulinemia or with more than 5 g/dl of IgG or IgA globulins.

Red Cell Volume

On six subjects plasma volume (Evans blue space) was determined before and 1 hr after an 85-km race in cross-country skiing. The total water loss during the 5- to 9.5-hr competition was estimated to be 5.9 liters, and at the time of measuring the reduction in body weight was 3.9 kg or 5.5% of the weight. The plasma volume was increased 0.41 or 11% (0.01 > P > 0.001). A similar study was undertaken with measurements of red cell volume (Cr51) on five subjects. The decrease in red cell volume was 0.081 or 3.2%. These findings are discussed in light of the small reduction in aerobic work capacity in combination with a marked decrease in total work output after the race. In five workers in a steel mill (three at a hot bank and two at a smelting furnace) the total water loss during an 8-hr shift in a hot environment was 3.9 liters and the reduction in body weight was 1.1 kg or 1.9% of the weight. The blood volume (I131) was increased by 0.23 liters or 3.5%. dehydration; blood volume Submitted on October 16, 1963

Volume Measurements

When estimated by the dilution of 51Cr-labeled red blood cells under nearly basal conditions, immature splenectomized pigs (n = 20) had a circulating red cell volume of 17.8 +/- 1.64 (SD) ml/kg. At an assumed body-to-large vessel hematocrit (BH:LH) ratio of 0.9, plasma volume was 49.6 +/- 3.12 ml/kg and blood volume 67.3 +/- 3.67 ml/kg. Sham-operated pigs (n = 20) had a circulating red cell volume of 16.2 +/- 1.39 ml/kg, a plasma volume of 51.1 +/- 3.42 ml/kg, and blood volume of 67.2 +/- 4.12 ml/kg. Kinetic analysis of early 51Cr loss from the circulating blood of the sham-operated pigs indicated a splenic red cell sequestration of 4.5 +/- 0.89 ml/kg and a t1/2 of 9.76 +/- 1.93 min for splenic red cell turnover. Epinephrine injection (n = 6) and physical restraint (n = 8) caused rapid mobilization of splenic red blood cells in sham-operated pigs. Volume estimates in splenectomized pigs (n = 7) based on simultaneous dilutions of 51Cr-labeled red blood cells and 125I-labeled bovine albumin gave circulating red cell, plasma, and blood volumes of 18.4 +/- 2.46, 60.7 +/- 4.01, and 79.0 +/- 3.51 ml/kg, respectively, and a BH:LH ratio of 0.756 +/- 0.029. The latter value may have reflected an overestimation of plasma volume by the 125I-labeled albumin procedure.

The Common

A method for simultaneous estimation of plasma volume, red cell volume and thiocyanate space in unanesthetized rats utilizing a polyethylene catheter in the common carotid artery with T-1824, P32-tagged red cells, and NaSCN was perfected and determinations were performed on 77 male albino rats. Determinations of plasma volume using T-1824 or I131-serum albumin in the same animal gave essentially identical results. Total blood volume was calculated as the sum of P32-red cell volume and T-1824-plasma volume and was found to be 5.75 ml/100 gm body weight in normal rats and 5.61 ml/100 gm in splenectomized rats. There was a wide variation in the Fcell values of normal rats but little in splenectomized rats. This difference was highly significant and was attributed to the presence of the spleen. The average thiocyanate space was found to be 33.0 ml and 35.8 ml/100 gm in normal and splenectomized rats, respectively.

Tourniquet Shock

The distribution of radioiodinated plasma and radioiron-labeled red blood cells between the liver, intestine and spleen were determined during the induction and development of tourniquet shock in mice. The data obtained indicate that plasma and red blood cells are distributed differentially throughout the splanchnic vasculature such that plasma volume of liver, intestine and spleen remain depressed for the entire shock interval, as does splenic red cell volume. After an early decline, the red cell volume of liver and intestine become elevated to a level above control. This differential distribution of plasma and red cells in liver and intestine is attributed to alterations in peripherovascular tone and suggests that a venous component becomes prominent late in shock and may act to pool blood out of active circulation.

Venous Resistance

The application of occluding tourniquets to both hind legs of unanesthetized mice produced widespread changes in the distribution of plasma and red cells throughout the peripheral circulation. Following tourniquet application the plasma volume within all tissues declined except for lung which remained unaltered and muscle which exhibited an increase. The red cell volume changed variably, declining in liver and spleen, rising in kidney and muscle and remaining unchanged in the other tissues analyzed. These changes were suggestive of a somewhat generalized increase in peripherovascular constrictor activity which included venous resistance vessels in addition to arterioles.
