Venoconstrictive Thigh Cuffs Impede Fluid Shifts During Simulated Microgravity
The microgravity environment associated with spaceflight has a number of significant effects on the human body, one of with is a net shift of fluid into the thoracocephalic compartment. The purpose of this study was to investigate the effects of venoconstrictive cuffs on the body's fluid distri...

| description | The microgravity environment associated with spaceflight has a number of significant effects on the human body, one of with is a net shift of fluid into the thoracocephalic compartment. The purpose of this study was to investigate the effects of venoconstrictive cuffs on the body's fluid distribution during simulated microgravity. This study was designed to test the following hypothesis: venoconstrictive thigh cuffs, inflated to 50 mmHg during simulated microgravity as modeled by 12 degree head down tilt (HDT), will impede venous flow resulting in increased leg blood volumes and thereby changing the whole body fluid distribution. |
