Definitions

1. Plasma volume was determined as the volume of distribution of albumin. (Web site)
2. The plasma volume (ml) is calculated by the activity concentration of the injection divided by the activity of the plasma sample obtained by extrapolation. (Web site)
3. To measure plasma volume, a substance must be used that does not readily penetrate capillary membranes but remains in the vascular system after injection.

Clrvol

1. ClrVol is the cleared plasma volume, calculated according to Eq (17). (Web site)

Pregnancy

1. Although red blood cell mass increases during pregnancy, plasma volume increases more, resulting in a relative anemia. (Web site)

Expansion

1. There is expansion of plasma volume without increase in interstitial water content.
2. This suggests the possibility that postexercise hypotension is an important mechanism in at least the initial stages of plasma volume recovery and expansion. (Web site)

Determination

1. Jeanatope is iodinated I-125 human serum albumin, typically injected to aid in the determination of total blood and plasma volume.

Red Blood Cells

1. The ratio of the red cell volume to the plasma volume can be decreased by lysing the red blood cells using a detergent or sonication.

Blood Plasma

1. Human serum albumin is one well known blood plasma protein that is used to expand plasma volume. (Web site)

Blood Volume

1. The plasma volume has a direct effect on the total blood volume, which has a direct effect on your blood pressure. (Web site)
2. In practicing subject methods, the plasma volume and the cell volume of anticoagulated are determined by the blood volume and the blood hematocrit. (Web site)

Changes

1. Because there is regulation of vessel radius by the endothelium it is hypothesized that hematocrit may be regulated near optimal by changes in plasma volume.
2. Data are presented which indicate that regulation of optimal hematocrit normally occurs through changes in plasma volume.
3. These values should be interpreted cautiously because they are concentrations affected by changes in plasma volume.

Sum

1. It is the sum of the plasma volume and erythrocyte volume. (Web site)

Rbcs

1. This occurs because although the production of RBCs does not change greatly, the plasma volume increases, i.e., the RBCs are "diluted". (Web site)

Red Cell Mass

1. The major components of blood are the red cell mass and plasma volume.

Water

1. These hormones, called natriuretic hormones, increase the excretion of water and electrolytes by the kidney, thus reducing the plasma volume to normal. (Web site)

Dehydration

1. For example, dehydration elevates these values, and increased plasma volume in pregnancy can diminish them without affecting the RBC mass.

Blood

1. Mannitol cranks up blood plasma volume by pulling interstitial fluid into the blood for an increase in plasma volume.
2. Blood plasma volume may be expanded by or drained to extravascular fluid when there are changes in Starling forces across capillary walls.
3. The use of glycerol acts to prolong fluid retention and thus have water available for sweating, cell hydration, and maintenance of blood plasma volume. (Web site)

Measurement

1. Recommended methods for measurement of red-cell and plasma volume. (Web site)
2. Measurement of plasma volume and red blood cell volume may provide a more accurate guide for blood transfusion requirements. (Web site)

Hypotension

1. For hypotension unresponsive to measures taken to increase plasma volume, dopamine or dobutamine i.v.

Postural Hypotension

1. Postural hypotension caused by chronic constriction of the arterial and venous beds leads to a reduction in plasma volume.

Rbc

1. As the initial salvo of phlebotomies are performed, the red blood cell (RBC) mass and plasma volume are reduced to normal levels.

Volume

1. In contrast, the volume of distribution was equivalent for the three molecules and approximately equal to the plasma volume (data not shown).

Albumin

1. Effect of therapeutic paracentesis on plasma volume and transvascular escape rate of albumin in patients with cirrhosis.
2. These substances as well as albumin are employedprincipally to expand plasma volume, carry oxygen, or enhance oxygen transport. (Web site)

Analyte

1. In practice of subject methods, the analyte may be viewed as being distributed between the cell volume and the plasma volume of anticoagulated blood. (Web site)

Hematocrit

1. In relative polycythemia, the hematocrit rises because of a loss of plasma volume without a corresponding decrease in red cells.
2. The hematocrit rises when the number of red blood cells increases or when the plasma volume is reduced, as in dehydration. (Web site)
3. Therapy with PROCRIT® results in an increase in hematocrit and a decrease in plasma volume which could affect dialysis efficiency.

Plasma Volume

1. The hypothetical analyte volume in anticoagulated blood is established as the sum of the plasma volume and 29% of the cell volume. (Web site)
2. The Vh is assumed to be the sum of the plasma volume and a fraction of the cell volume of anticoagulated blood. (Web site)
3. In preferred practice of the invention, the model for Vh is the sum of the plasma volume and a fraction of the blood cell volume of anticoagulated blood. (Web site)
