Microgravity (μG) induced orthostatic intolerance (OI) in astronauts is characterized by a marked decrease in cardiac output (CO) in response to an orthostatic stress. Since CO is highly dependent on venous return, alterations in the resistance to venous return (RVR) may be important in contributing to OI. The RVR is directly dependent on arterial compliance (Ca), where aortic compliance (Cao) contributes up to 60% of Ca. We tested the hypothesis that μG induced changes in Ca may represent a… CONTINUE READING
