Lower body negative pressure chamber for MRI
FBE, Flinders Biomedical Engineering, have developed a lower body negative pressure (LBNP) chamber specifically for use in an MRI. It will be used to monitor cardiac effectiveness by simulating the process of standing upright. Negative pressure, or external decompression, is applied to the lower body using a vacuum of 30 millimeters of mercury. LBNP can be used to study orthostatic intolerance (e.g. fainting when standing), to assess cardiovascular function and to simulate severe hemorrhage.
