| ==Humans==
| |
| A typical adult has a blood volume of approximately between 4.7 and 5 litres, with females generally having less blood volume than males.<ref>{{cite web|url=http://hypertextbook.com/facts/1998/LanNaLee.shtml|title=Volume of Blood in a Human|work=The Physics Factbook|first=Lan Na|last=Lee|year=1998}}</ref> Blood volume is regulated by the [[kidney]]s.
| |
| | |
| Blood volume (BV) can be calculated given the [[hematocrit]] (HC; the fraction of blood that is [[red blood cell]]s) and plasma volume (PV):
| |
| :<math>BV = \frac{PV}{1-HC}</math>
| |
| | |
| Diagnostic technologies are commercially available to measure human blood volume. A recent radionucleotide study called BVA-100, Blood Volume Analysis is the only FDA approved instrument that provides a measure of Red Blood Cells and Plasma with 98% accuracy.
| |
| | |
| Blood volume measurement is indicated for the diagnosis and treatment patients suffering from [[Congestive Heart Failure]], [[Chronic hypertension]], [[Renal Failure]] and Critical Care.

The title of the writer is Numbers but it's not the most masucline title out there. Hiring is my occupation. Puerto Rico is where he and his spouse live. To gather cash is one of the issues I love most.
