Impedance plethysmography is used to measure venous blood volume changes in the extremities. Electrodes and a pressure cuff are attached to an extremity. As the pressure cuff is inflated and electrical resistance increases, the quality of venous blood flow can be demonstrated. This non-invasive test does not use dye, does not require walking on a treadmill, nor is it uncomforta-ble.
