Abstract
A vascular testing system includes a first pressure cuff assembly positionable about a limb of a patient and a controller. The first pressure cuff assembly includes a pressure bladder and a first array of acoustic sensors, the first array including a plurality of acoustic sensor elements arranged circumferentially relative to the pressure bladder. The controller is configured to concurrently sense vascular data at two or more discrete testing locations utilizing at least two different sets of the acoustic sensors of the first array each positioned at or near one of the discrete testing locations. Each set of the acoustic sensors includes one or more of the plurality of acoustic sensor elements.
