Apparatus and Method For Assessing Vascular Health
First Claim
1. A method of determining a vascular condition of an individual, comprising:
- performing a first conductivity measurement of an extremity of the individual at a first elevation;
elevating the extremity of the individual to a second elevation;
performing a second conductivity measurement of the extremity at the second elevation;
comparing the first conductivity measurement and the second conductivity measurement to determine a conductivity displacement Δ
σ
of the extremity responsive to the elevation change of the extremity.

Abstract
Apparatus and methods for utilizing conductivity measurements to assess vascular health or to diagnose vascular conditions are disclosed. An exemplary method includes performing a first conductivity measurement of an extremity at a first elevation; elevating the extremity to a second elevation; performing a second conductivity measurement at the second elevation; and comparing the first conductivity measurement and the second conductivity measurement to determine a conductivity displacement Δσ. Another exemplary method includes maintaining a conductivity sensor adjacent to an individual for a period of time; performing a series of conductivity measurements; using the series of conductivity measurements to determine the transient behavior of the conductivity over the period of time; and using the transient behavior of the conductivity to assess the vascular health of the individual. A conductivity sensor and platform unit for performing conductivity measurements are also disclosed.
