Blood Volume Studies in Healthy Children

Blood volume studies in healthy children.

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...

Plasma and blood volume studies in malnourished iraqi children.

I . The plasma and blood volumes of twenty-eight Iraqi children were measured. Twentyfour of them were malnourished in varying degrees and four were normal children who acted as controls. None of the children was anaemic. 2. Therc was an increase in the plasma and blood volumes per unit body-weight correlating with the degree of malnourishment (P < 0.001). 3. There was little variation in the v...

Blood Volume in Normal Infants and Children.

Blood volume and circulation time in children.

By means of these two methods there is determined only that portion of the total blood volume which is in rapid circulation, the other part, the so-called stored or depot blood, which is moving slowly or is almost stationary, being neglected. The organs which may act as blood depots are the spleen, the liver, the intestines, the sub-papillary plexus of the skin and possibly the muscles. The gre...

Ultrasonographic assessment of global cerebral blood volume in healthy adults.

The authors describe a new ultrasonographic method for analysis of global cerebral blood volume (CBV) and its application under controlled hyperventilation. CBV was determined as the product of global cerebral blood flow volume (CBF) and global cerebral circulation time. CBF was measured by duplex sonography and calculated as the sum of flow volumes in both internal carotid arteries and vertebr...
