ABSTRACT:
A method of vascular testing includes inflating a cuff at a vascular location, controllably deflating the cuff, producing a pressure waveform while deflating the cuff, and producing an output representing a pressure at which blood flow returns, while deflating the cuff, based upon analysis of the pressure waveform. Further, a testing system for measuring vascular pressures according to the present invention includes a pressure applicator, a pressure sensor, and a diagnostic test unit. The pressure applicator is positionable along exterior portions of a human body for dynamically applying pressure to a desired vascular location. The pressure sensor is capable of detecting oscillations in a pressure at the pressure applicator. The testing system is capable of determining a peak pressure oscillation amplitude, and is also capable of determining, as a function of the peak pressure oscillation amplitude, a pressure of a return of flow at the desired vascular location as pressure applied to the desired vascular location by the pressure applicator is lessened.
