Bed Rest Standard Measures: Plasma Volume (BRSMPV)
Research Area:
Cardiovascular physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

The objective of this test was to measure plasma volume to aid in the proper assessment of hemodynamic parameters, vascular responses, and cardiac size and function. The investigators hypothesized that plasma volume losses will be similar to those following space flight. They expected to see changes in blood volume for subjects following extended periods of bed rest.
