Preservation of blood volume during XXXX removal in @entity1985 subjects.

During the gradual removal of @entity4 with diuretics in 21 @entity4 @entity1 with the @entity1985 ( @entity1985 ) we monitored blood volume. For comparison, nine healthy subjects were studied after equilibration on diets containing 20, 200, and 1138 mEq @entity1372 . The initial extracellular fluid volume (ECFV) in the @entity1 exceeded the final ECFV by 63.4 +/- 8.4%. In 10 @entity1 with a very low plasma oncotic pressure (8.2 +/- 0.4 mm Hg, Group 1), the blood volume changed little. In Group 2 (plasma oncotic pressure 13.4 +/- 1.0 mm Hg), it was 11.0 +/- 2.5% higher at entry than after @entity4 withdrawal. In the normal volunteers, the highest @entity1372 intake raised the ECFV by 21.4 +/- 4.1%. The accompanying rise in blood volume, 11.2 +/- 3.0%, was larger than in the @entity1 of Group 1 (2.4 +/- 1.9%, P less than 0.04), but not of Group 2 (8.1 +/- 1.9%, @entity1985 ) at similar degrees of expansion. There was no difference in blood volume between the @entity4 -free @entity1 and the normal subjects at low- @entity1372 diet. The course of blood pressure and @entity1011 clearance during @entity4 removal gave no evidence that functional @entity3485 was induced, but the plasma @entity916 activity was higher than in the normal subjects at similar degrees of expansion. We conclude that the blood volume to ECFV relationship curve is flattened in the presence of @entity4988 . Thus, the increase in blood volume that normally follows ECFV expansion is less in @entity1 with the @entity1985 , but a drop below normal upon removal of @entity4 is absent also.
