Circulating blood volume (CBV) was prospectively measured in patients with almost solely smoke inhalation injury (Group I: 10 patients) and in patients with severe cutaneous burn (Group B: 6 patients) consecutively until 96 hours after injury, to assess the effect of either injury on intravascular volume status by the pulse dye-densitometry method. All participants were treated by an ordinary f...

H UMAN PERIPHERAL BLOOD polymorphonuclear leukocytes (PMNs) possess surface receptors for a variety of ligands which, if bound, lead to its activation.’ Upon binding the ligand, PMNs will undergo membrane potential changes,6 reduce molecular oxygen,7 aggregate,8’9 release granule contents,7 adhere to certain surfaces,’#{176} phagocytize,” and move or chemotax.’2 Recently, the data that these re...

Among the earliest recorded experiments on the tion of the blood volume are those of Bischoff (1856, 1858) and Weicker (1858), who by exsanguinationm directly the amount of blood obtained from the bodies of executed criminals. Since that time much genuity has been xrcised in devising methods of esimating blood volume which would conbine accuracy with ease of application to the living human subj...

Cardiovascular system One of the major alterations to the cardiovascular system seen in the pregnant patient is that of blood volume. During pregnancy, an increase is seen in plasma volume (up to 50%), red blood cell volume (up to 20%) and total blood volume (up to 35%). Healthy women in a normal first pregnancy increase their plasma volume from a nonpregnant level by approximately 1250 ml. In ...
