Determination of Blood Volume in Nephrotic Patients

American Journal of Nephrology, 1989
We assessed blood volume (BV) in 20 edematous patients with nephrotic syndrome and in 32 subjects without renal or other disease liable to induce BV variation. Two methods were chosen, one using 131I-albumin and the other 51Cr red blood cells. Among the 20 patients, 11 presented minimal-change lesions, and 9 had histological glomerular impairment.

Blood volume determination with sodium fluorescein and radioactive chromium--a clinical comparison of methods.

Infusionstherapie und Transfusionsmedizin, 1994

Blood volume determination by the carbon monoxide method using a new delivery system: accuracy in critically ill humans and precision in an animal model.

Critical Care Medicine, 1999
OBJECTIVE To evaluate accuracy and repeatability of blood volume determinations made by the carbon monoxide method, using a ventilator-driven administration system.

Blood volume determination in the ringed seal, Phoca hispida.

Canadian Journal of Zoology, 1978
Red cell, plasma, and total blood volumes were determined in three ringed seals, Phoca hispida, through simultaneous labelling of both red cells and plasma. Total blood volumes were 139, 140, and 158 ml/kg of whole body weight ( ml/kg).

Blood volume determination as a function of hematocrit and mass in three preservative solutions and saline.

American Journal of Clinical Pathology, 1994
Accurate blood volume determination is useful both clinically and in research. In many instances, however, direct measurement of blood volume is impractical due to the risk of bacterial contamination.

TRANSFUSION THERAPY GUIDED BY BLOOD VOLUME DETERMINATIONS

Survey of Anesthesiology, 1962
Abstract Data are presented to demonstrate the accuracy and convenience of a new instrument for rapid, semiautomatic blood volume determination by radioactive tracer dilution and the usefulness of such determinations for guiding transfusion therapy in surgical patients.

The Determination of the Blood Volume of Insect Larvæ.

Annals of the Entomological Society of America, 1931
In physiological and toxicological studies of insects it is often desirable to know the volume occupied by the blood. Dry weight determinations of the whole insect furnish information upon the total quantity of body water, but tell nothing of its distribution, i.e., the quantity present in the blood and that held in the tissues.

Whole Blood Volume Determinations

Archives of Internal Medicine, 1974
To the Editor. —The work of Valeri and Cooper ( Arch Intern Med 132: 534-538, 1973) shows well the problem of measuring plasma volume accurately with sodium chromate Cr 51 serum albumin. But the authors come to the unwarranted conclusion that the best method of determining whole blood volume is to measure only red blood cell (RBC) mass.

Errors of the backextrapolation method in determination of the blood volume

Physics in Medicine and Biology, 1999
Backextrapolation is an empirical method to calculate the central volume of distribution (for example the blood volume). It is based on the compartment model, which says that after an injection the substance is distributed instantaneously in the central volume with no time delay. The occurrence of recirculation is not taken into account.
