Chronic instrumentation for right heart cardiovascular studies in a human surrogate model

The Laboratory for Aerospace Cardiovascular Research (LACR) is a center for studying the effects of micro-and high (9Gz) gravitational forces on the cardiovascular system. Prior research efforts focused on determining pressure-volume-flow relationships of the left heart for altered G-environmcnts. This paper will describe the current right/left heart model that features less traumatic chronic implantation. This model has enabled LACR to evaluate right/left heart cardiovascular function in chronically instrumented non-human surrogate model during static rotational tilt, NASA KC-135 micro-G parabolas, and high G centrifugation.
