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.

Plasma volume late in pregnancy
American Journal of Obstetrics and Gynecology, 1950Abstract Plasma volume was determined by chromatographic extraction and spectrophotometric determination of Evans blue in pregnant women a month before delivery and at term, as well as in nonpregnant control subjects. The mean value at term was not significantly lower than that at the the thirty-sixth week.

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.

ALBUMIN‐CONTAINING PLASMA VOLUME EXPANDERS
Australian and New Zealand Journal of Surgery, 1977Human albumin‐containing solutions have been used as plasma volume expanders and in the management of severe hypoproteinaemia for over 30 years. Modern indications for their use are described in some detail. These include the management of shock, burns, adult respiratory distress syndrome, and priming of the cardio‐pulmonary bypass pump.

STATUS OF HUMAN PLASMA AS A PLASMA VOLUME EXPANDER
Plastic and Reconstructive Surgery, 1960Review of Plasma Studies Although transfusions of plasma were suggested, they were not tried as substitutes for blood transfusions during World War I. Numerous studies of plasma were made during the period between World War I and World War II, but most of them are not particularly relevant to this report. Wartime enthusiasm for the use of plasma began

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 ...

Neonatology, 1977
Two groups of 15 neonatal piglets underwent arteriovenous perfusion with the chest closed, at normothermia and without an oxygenator in the system until complete mixing of the blood and priming fluid was accomplished. The extracorporeal circuit was primed in one group with a warm (38 °C) buffered Ringer-lactate solution, and in the second group with an

Plasma volume changes after infusion of various plasma expanders
Resuscitation, 1976In the immediate post-operative period after moderate surgical procedures, 1 litre of a colloid solution or saline was given intravenously. The plasma volume expansion after infusion of dextran 70 (Macrodex), hydroxyethylstarch (Volex), polygelatin (Haemaccel), albumin and saline was found to be between 790 and 180 ml. The most efficent plasma expander

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.

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 ...
