  • Automated Non-Invasive Arterial Pressure Device in Normals and in Patients with Peripheral Arterial Disease Rochester, Minn.

    The purpose of this study is to determine the accuracy of an automated non-invasive arterial pressure device when assessing people with peripheral arterial disease.   The arterial pressure from each limb and calculated ABI’s from standard non-invasive arterial vascular testing verses automated non-invasive arterial device will be compared.

  • Ultrasound Imaging of the Internal Jugular Vein Using a Novel Approach (Parotid Window) Rochester, Minn.

    Ultrasound imaging has the potential to greatly expand our ability to study venous blood flow (or obstruction) in the neck, particularly when the obstruction is caused by positional extrinsic compression of the vein.  This study will determine the feasibility of performing ultrasound assessment of the IJV in a general population.  In addition, if ultrasound proves feasible for this purpose we will simultaneously determine “normal” values for certain baseline characteristics of the IJV such as size, flow, flow velocity, etc.
