Plasma Volume Changes in the Neonate
Archives of Pediatrics & Adolescent Medicine, 1962The primary objective of this study was to demonstrate shifts of plasma between vascular and extravascular spaces during the first 2½ hours of life. Such shifts in plasma volume have been postulated by Marks et al. in order to account for the significant rise in packed cell volume that they demonstrated within the first 2½ hours of life.

Safety of Plasma Volume Expanders
The Journal of Clinical Pharmacology, 2011Hypovolemia from a range of etiologies can lead to severe morbidity and mortality unless blood volume and tissue perfusion are restored. The treatment of hypovolemia has included the improvement and restoration of blood volume loss by the intravenous infusion of plasma expanding therapeutic agents.

The Physics of Fluids, 1967
A formula is derived for the force exerted by charged particles on neutral particles in a gaseous discharge. It is shown that (a) the discussions of Langmuir and Druyvesteyn with respect to the reaction force on the neutral gas particles resulting from the net rate of momentum transfer by the charged particles to the wall of the discharge tube are ...

Plasma volume nomograms for use in therapeutic plasma exchange
Transfusion, 1983ABSTRACT: Nomograms have been developed for the convenient estimation of the plasma volumes of patients undergoing therapeutic plasma exchange (TPE), based on equations employing height, body weight, and hematocrit. These nomograms are offered as an aid to prescribing continuous‐flow TPE procedure exchange volumes.

Body Water, Plasma Volume, and Erythrocyte Volume in Sheep
American Journal of Veterinary Research, 1970SUMMARY Total body water, plasma volume, total circulating erythrocyte volume, venous packed cell volume (pcv), and total body pcv were measured in 40 sheep (mean body weight, 32.6 kg.). The mean fluid volumes were 647.0 ml. of water, 53.2 ml. of plasma, and 21.1 ml. of erythrocytes per kilogram of body weight.

JAMA: The Journal of the American Medical Association, 1941
To the Editor:— In studying the behavior of the plasma volume during diuresis it is apparent that changes in the plasma volume will depend for their magnitude on the intensity of the diuresis in proportion to the volume of the plasma. To illustrate the superiority of the edematous dog to the edematous cardiac patient for experimental purposes in this ...

Estimating plasma volume from red cell volume
Nuclear Medicine Communications, 1999Following the withdrawal of the only licensed supply of 125I-HSA in 1997, most UK centres now simply estimate plasma volume from a knowledge of the red cell volume and venous haematocrit. We compared measured and estimated plasma volume in 107 consecutive patients who had had red cell and plasma volume measured independently in the conventional way. In

Exercise stroke volume relative to plasma-volume expansion
Journal of Applied Physiology, 1988The effects of plasma-volume (PV) expansion on stroke volume (SV) (CO2 rebreathing) during submaximal exercise were determined. Intravenous infusion of 403 +/- 21 ml of a 6% dextran solution before exercise in the upright position increased SV 11% (i.e., 130 +/- 6 to 144 +/- 5 ml; P less than 0.05) in untrained males (n = 7). Further PV expansion (i.e.

DETERMINATION OF PLASMA VOLUME
Archives of Internal Medicine, 1931In the first paper 1 a method for the accurate evaluation of brilliant vital red in the plasma was described. If the measurement of the dye concentration is to serve as an index of the total plasma volume, the mixing of the injected dye with the plasma must be complete throughout the circulation before there is any appreciable loss of dye. Two problems,
